@ -0,0 +1,242 @@
+v1.4.0 30-May-2017
+------------------
+
+- extended toString() method of all model node classes to print its
+  complete submodel tree.
+
+- merged all projects openiec61850, jositransport, josistack,
+  openiec61850-clientgui, and openiec61850-sample into a single
+  project "openiec61850".
+
+- removed all slf4j logging for client part. Thus if library is only
+  used on client side slf4j is no longer needed.
+
+- replaced sample client and server by console applications
+
+- fixed setting functional constraint correctly for all BRCB
+  elements. Thanks to Stefan Goldmann.
+
+- fixed client side processing of reports when inclusion bit string is
+  not padded with zeros, thanks to Thomas Schönle from Bachmann
+
+- fixed ServerSAP.stop() to close timer threads correctly
+
+- made several imports in OSGi MANIFEST file optional because they are
+  not necessarily required
+
+- library now depends on jASN1 1.8.0
+
+
+v1.3.3 09-Mar-2017
+------------------
+
+- fixes bug introduced in 1.3.2: report control block instance names
+  should start at 01 instead of 00
+
+- library now depends on jASN1 1.7.1
+
+v1.3.2 01-Mar-2017
+------------------
+
+- fixes object reference of child attributes of array elements: old:
+  LD/LN.DO.Array(1)child, new LD/LN.DO.Array(1).child
+
+- fixes setting of RptEna DA in server to true when reports are enabled.
+
+- fixes reading report control blocks with "max" attribute greater 1
+  from SCL file
+
+- added check whether received BitString has correct size before setting it
+  in model
+
+v1.3.1 24-Feb-2017
+------------------
+
+- fixed TapCommand data attribute default value
+
+- types based on BdaBitString now check in setValue(byte[] value)
+  whether passed byte array has correct length
+
+
+v1.3.0 17-Jan-2017
+------------------
+
+- fixed bug that urcb reservation was not canceled after connection
+  was closed
+
+- fixed support for reserving buffered report control blocks on the
+  client side thanks to Bo Orsted Andresen
+
+- fixed support for receiving buffered and unbuffered reports when the
+  data set reference is not part of the report thanks to Bo Orsted
+  Andresen
+
+- fixed bug in parsing scl file, in some cases predefined values were
+  not set, thanks to Wu Yongming
+
+- added support for parsing ObjRef in SCL file
+
+- added support for multiple report control block instances by
+  specifying RptEnabled max attribute in SCL file
+
+v1.2.0 20-Mar-2016
+------------------
+- changed license from LGPL to Apache 2.0
+- added methods to ServerModel class to retrieve BRCBs on the client
+  side, thanks to Thomas Saabye from EURISCO
+- added support for parsing "Val" elements inside "DA" elements of SCL
+  file
+- several minor bug fixes
+
+v1.1.1 11-Dec-2014
+------------------
+- set default max TPDU size to 1024
+- fix: server stops sending reports when client closed association
+- fix in sample model to enable general interrogation
+
+v1.1.0 17-Oct-2014
+------------------
+- fixed ServerSap.stop()
+- added possibility change more settings in ClientSap
+- setDataSetValues will now only call a single call back function of a
+  server application. The syntax of the call back function had to be
+  changed for that.
+- fixed doclint errors and warnings. doclint is used by Java8
+
+v1.0 31-Jul-2014
+----------------
+- added support for reporting on server side.
+- minor bug fixes
+- improvements to logging messages
+- added maxtpdu size to all Transport Layer Connection Requests
+  (thanks to Michael Volz)
+- client can now receive reports via callback method
+- improved documentation
+- fixed build file for newest gradle
+- improved documentation
+
+v0.17.1 27-Jan-2014
+-------------------
+- extracted jOSIStack lib from openiec61850 lib so it can be used
+  separately (e.g. for the TASE.2 protocol)
+- fixed bugs in client Report functionality
+- readded ClientReportingSample application
+- fixed copying of arrays
+- support for decoding authentication value, though the authentication
+  value is NOT being checked at the moment
+- added full server side support for nonpersistent DataSets
+- fixed bug in runSampleServer.bat script
+- jars are now uploaded to the central maven repository
+
+v0.16.0 03-Sep-2013
+-------------------
+- renamed many functions and classes
+- added Client GUI project to easily browse the device model of an IEC
+  61850 IED.
+- openiec61850-client, -server, -common and jmms where combined into a
+  single openiec61850 library. The split was of no real use and caused
+  split package problems in OSGi environments.
+- client ACSI functions now throw two types of exceptions: IOException
+  (fatal exception, client needs to reconnect to server) and
+  ServiceError for Errors that did not affect the active
+  assocition/connection.
+- The way the server library works was completely changed: DataSources
+  no longer exist and there is no need for property files anymore. The
+  readValue() callback method in the DataSource is no longer needed
+  because GetDataValues requests are handled by the server library
+  without consulting the server application. Instead the server
+  application now has to fill the internal model of the server library
+  with up to date values. This change was necessary in order to be
+  able to efficiently implement reporting and controling services in
+  the future.
+- Basic control services are now part of the library and no longer
+  have to be handled by the server application.
+- Several bug fixes in the SCL-parser
+- fix so that FunctionalConstraints such as GS that are not supported
+  by openIEC61850 yet do not cause a null pointer exception when they
+  are part of a DataSet
+
+v0.14.4 30-Oct-2012
+-------------------
+- fixed another bug when decoding Float64 
+- getDataDefinition of all kinds of DataObjects and DataAttributes now
+  possible
+- modified toString() function of most DataAttributes to print more
+  valuable information
+
+v0.14.3 18-Sep-2012
+-------------------
+- fixed decoding of Float32 and Float64 
+- fixed getChildren(fc) Function in LogicalNode
+
+v0.14.2 23-Aug-2012
+-------------------
+- major refactoring to make code more efficient and easier to
+  maintain. Many classes have been renamed and/or relocated.
+- the ability to use different SCSM was completely removed because
+  only one mapping existed so far: the MMS mapping. No other Mapping
+  seems to have a chance against MMS simply because MMS is already in
+  use and works.
+- note that the syntax of the properties file for the StandaloneServer
+  changed a little, see the sampeServer for details
+
+v0.12.0 31-Jul-2012
+-------------------
+- changed from LGPLv3 to LGPLv2.1
+- replaced OCTET_STRING64, OCTET_STRING8 and so on with a general
+  OCTET_STRING class
+- the same was done for UNICODE_STRING and VISIBLE_STRING
+- client no longer hangs when receiving ApplError Reports
+
+v0.11.0 02-Jul-2012
+-------------------
+- new jASN1 version that can decode empty Object Identifiers
+- added mms authentication capability
+- fixed multi thread issues in TSAPConnection of MMS mapping
+- added FLOAT64 from IEC61400-2
+- added SampleReportClient to demonstrate how to use reporting with the client
+- some improvements to client receiver thread
+- some other small bug fixes
+
+v0.10.0 14-Mai-2012
+-------------------
+- restructuring: code moved to src folder
+- new jASN1 version which fixes bug in decoding empty bitstrings
+- receving "Check" data does not cause errors anymore
+- ASN.1 buffers are automatically resized in the client
+
+v0.9.9 29-Mar-2012
+------------------
+- added DataSet Services for client and server
+- added getReport methods and processReport for the client -> they
+  will get a report from the queue and return a report object with the
+  updated data
+- fixed getDataValues for array structures 
+- disabled sending SpecificationWithResult in read request because
+  some clients cannot cope with it
+- fixed bug in RFC 1006 part
+- added receiver thread in client so that reports can be received at any time
+- added VisibleString65 to be compatible with some version1.0 servers
+- avoid srcRef == 0 because some servers cannot cope with it 
+
+v0.9.8 22-Feb-2012
+------------------
+- fixed path in runSampleServer.sh and runSampleClient.sh
+
+0.9.7 21-Feb-2012
+-----------------
+- small bug fix in T-Sel encoding/decoding in TConnection.java -
+  thanks to Johannes Schmidt from University of Leipzig
+
+v0.9.6 20-Feb-2012
+------------------
+- when importing Eclipse projects: GRADLE_HOME was replaced by GRADLE_USER_HOME
+- removed duplicate entries from tar distribution file
+- Remote TSAPs can now be addressed using a T-Selector. The client can
+  set the T-Selector like this:
+  MmsScsmClientSAP clientSAP = new MmsScsmClientSAP();
+  clientSAP.acseSAP.tSAP.tSelRemote = new byte[] { 0, 1 };
+
+v0.9.5 06-Feb-2012
+------------------
+- first version

+
+      "You" (or "Your") shall mean an individual or Legal Entity

+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+

+  complete submodel tree.
+
+- merged all projects openiec61850, jositransport, josistack,
+  openiec61850-clientgui, and openiec61850-sample into a single
+  project "openiec61850".
+

+  used on client side slf4j is no longer needed.
+
+- replaced sample client and server by console applications

+  not necessarily required
+
+- library now depends on jASN1 1.8.0
+
+
+v1.3.3 09-Mar-2017
+------------------
+
+- fixes bug introduced in 1.3.2: report control block instance names
+  should start at 01 instead of 00

+
+- fixes setting of RptEna DA in server to true when reports are enabled.
+
+- fixes reading report control blocks with "max" attribute greater 1
+  from SCL file
+
+- added check whether received BitString has correct size before setting it
+  in model
+
+v1.3.1 24-Feb-2017
+------------------
+
+- fixed TapCommand data attribute default value
+
+- types based on BdaBitString now check in setValue(byte[] value)
+  whether passed byte array has correct length
+
+
+v1.3.0 17-Jan-2017
+------------------
+
+- fixed bug that urcb reservation was not canceled after connection
+  was closed
+
+- fixed support for reserving buffered report control blocks on the
+  client side thanks to Bo Orsted Andresen
+
+- fixed support for receiving buffered and unbuffered reports when the
+  data set reference is not part of the report thanks to Bo Orsted
+  Andresen
+
+- fixed bug in parsing scl file, in some cases predefined values were
+  not set, thanks to Wu Yongming
+
+- added support for parsing ObjRef in SCL file
+
+- added support for multiple report control block instances by
+  specifying RptEnabled max attribute in SCL file
+
+v1.2.0 20-Mar-2016
+------------------
+- changed license from LGPL to Apache 2.0
+- added methods to ServerModel class to retrieve BRCBs on the client
+  side, thanks to Thomas Saabye from EURISCO
+- added support for parsing "Val" elements inside "DA" elements of SCL
+  file
+- several minor bug fixes
+
+v1.1.1 11-Dec-2014
+------------------
+- set default max TPDU size to 1024
+- fix: server stops sending reports when client closed association
+- fix in sample model to enable general interrogation
+
+v1.1.0 17-Oct-2014
+------------------
+- fixed ServerSap.stop()
+- added possibility change more settings in ClientSap
+- setDataSetValues will now only call a single call back function of a
+  server application. The syntax of the call back function had to be
+  changed for that.
+- fixed doclint errors and warnings. doclint is used by Java8
+
+v1.0 31-Jul-2014
+----------------
+- added support for reporting on server side.
+- minor bug fixes
+- improvements to logging messages
+- added maxtpdu size to all Transport Layer Connection Requests
+  (thanks to Michael Volz)
+- client can now receive reports via callback method
+- improved documentation
+- fixed build file for newest gradle
+- improved documentation
+
+v0.17.1 27-Jan-2014
+-------------------
+- extracted jOSIStack lib from openiec61850 lib so it can be used
+  separately (e.g. for the TASE.2 protocol)
+- fixed bugs in client Report functionality
+- readded ClientReportingSample application
+- fixed copying of arrays
+- support for decoding authentication value, though the authentication
+  value is NOT being checked at the moment
+- added full server side support for nonpersistent DataSets
+- fixed bug in runSampleServer.bat script
+- jars are now uploaded to the central maven repository
+
+v0.16.0 03-Sep-2013
+-------------------
+- renamed many functions and classes
+- added Client GUI project to easily browse the device model of an IEC
+  61850 IED.
+- openiec61850-client, -server, -common and jmms where combined into a
+  single openiec61850 library. The split was of no real use and caused
+  split package problems in OSGi environments.
+- client ACSI functions now throw two types of exceptions: IOException
+  (fatal exception, client needs to reconnect to server) and
+  ServiceError for Errors that did not affect the active
+  assocition/connection.
+- The way the server library works was completely changed: DataSources
+  no longer exist and there is no need for property files anymore. The
+  readValue() callback method in the DataSource is no longer needed
+  because GetDataValues requests are handled by the server library
+  without consulting the server application. Instead the server
+  application now has to fill the internal model of the server library
+  with up to date values. This change was necessary in order to be
+  able to efficiently implement reporting and controling services in
+  the future.
+- Basic control services are now part of the library and no longer
+  have to be handled by the server application.
+- Several bug fixes in the SCL-parser
+- fix so that FunctionalConstraints such as GS that are not supported
+  by openIEC61850 yet do not cause a null pointer exception when they
+  are part of a DataSet
+
+v0.14.4 30-Oct-2012
+-------------------
+- fixed another bug when decoding Float64 
+- getDataDefinition of all kinds of DataObjects and DataAttributes now
+  possible
+- modified toString() function of most DataAttributes to print more
+  valuable information
+
+v0.14.3 18-Sep-2012
+-------------------
+- fixed decoding of Float32 and Float64 
+- fixed getChildren(fc) Function in LogicalNode
+
+v0.14.2 23-Aug-2012
+-------------------
+- major refactoring to make code more efficient and easier to
+  maintain. Many classes have been renamed and/or relocated.
+- the ability to use different SCSM was completely removed because
+  only one mapping existed so far: the MMS mapping. No other Mapping
+  seems to have a chance against MMS simply because MMS is already in
+  use and works.
+- note that the syntax of the properties file for the StandaloneServer
+  changed a little, see the sampeServer for details
+
+v0.12.0 31-Jul-2012
+-------------------
+- changed from LGPLv3 to LGPLv2.1
+- replaced OCTET_STRING64, OCTET_STRING8 and so on with a general
+  OCTET_STRING class
+- the same was done for UNICODE_STRING and VISIBLE_STRING
+- client no longer hangs when receiving ApplError Reports
+
+v0.11.0 02-Jul-2012
+-------------------
+- new jASN1 version that can decode empty Object Identifiers
+- added mms authentication capability
+- fixed multi thread issues in TSAPConnection of MMS mapping
+- added FLOAT64 from IEC61400-2
+- added SampleReportClient to demonstrate how to use reporting with the client
+- some improvements to client receiver thread
+- some other small bug fixes
+
+v0.10.0 14-Mai-2012
+-------------------
+- restructuring: code moved to src folder
+- new jASN1 version which fixes bug in decoding empty bitstrings
+- receving "Check" data does not cause errors anymore
+- ASN.1 buffers are automatically resized in the client
+
+v0.9.9 29-Mar-2012
+------------------
+- added DataSet Services for client and server
+- added getReport methods and processReport for the client -> they
+  will get a report from the queue and return a report object with the
+  updated data
+- fixed getDataValues for array structures 
+- disabled sending SpecificationWithResult in read request because
+  some clients cannot cope with it
+- fixed bug in RFC 1006 part
+- added receiver thread in client so that reports can be received at any time
+- added VisibleString65 to be compatible with some version1.0 servers
+- avoid srcRef == 0 because some servers cannot cope with it 
+
+v0.9.8 22-Feb-2012
+------------------
+- fixed path in runSampleServer.sh and runSampleClient.sh
+
+0.9.7 21-Feb-2012
+-----------------
+- small bug fix in T-Sel encoding/decoding in TConnection.java -
+  thanks to Johannes Schmidt from University of Leipzig
+
+v0.9.6 20-Feb-2012
+------------------
+- when importing Eclipse projects: GRADLE_HOME was replaced by GRADLE_USER_HOME
+- removed duplicate entries from tar distribution file
+- Remote TSAPs can now be addressed using a T-Selector. The client can
+  set the T-Selector like this:
+  MmsScsmClientSAP clientSAP = new MmsScsmClientSAP();
+  clientSAP.acseSAP.tSAP.tSelRemote = new byte[] { 0, 1 };
+
+v0.9.5 06-Feb-2012
+------------------
+- first version

+
+== Intro
+
+OpenIEC61850 is a library implementing the IEC 61850 standard based on
+the MMS mapping for client and server communication. It is licensed
+under the Apache 2.0 license. OpenIEC61850 includes a console client
+and server as well as a gui client.
+    
+=== Distribution
+
+After extracting the distribution tar file the OpenIEC61850 library
+can be found in the build/libs-all folder. For license information
+check the _license_ directory in the distribution.
+
+==== Dependencies
+
+Besides the OpenIEC61850 library the folder _build/libs-all/_ contains the
+following external libraries:
+
+* *jasn1* - a library from the jASN1 project doing BER
+   encoding/decoding, Copyright 2011-17 Fraunhofer ISE, Author: Stefan

+
+* *slf4j-api* - a popular logging API. It is only needed if
+   openiec61850 is used to implement a server. The client part does
+   not log anything.  License: MIT, http://www.slf4j.org
+
+* *logback-core/logback-classic* - an actual logger implementation of
+   the slf4-api. It is used by the console server application to
+   output log information. It can be replaced by a logger of your
+   choice that supports the slf4j API. Like slf4j it is only needed
+   for server implementations. License: EPLv1.0 and LGPLv2.1,
+   http://logback.qos.ch
+
+* *jcalendar* - a calendar library needed by the client GUI. You don't
+   need this dependency if you don't use the client gui.  (C)

+
+    
+=== Console & GUI Applications
+
+You can execute the console client and server through the scripts
+found in the folder _run-scripts_.  Executing the scripts without any
+parameters will print help information to the screen. Note that under
+Unix/Linux you need root privilages if you want the server to listen
+on any port lower than 1000.
+
+Instead of running the applications from the terminal you can create
+Eclipse project files as explained in our
+link:https://www.openmuc.org/faq/gradle_getting_started/[FAQs] and run
+them from within Eclipse.
+
+    
+=== OSI Stack
+
+The OpenIEC61850 library includes an OSI stack implementation as it is
+needed by the IEC 61850 MMS mapping. The API of the OSI stack and the
+OSI transport layers are made public so that they can be used by other
+projects.
+
+* *josistack* - implements the Application Control Service Element
+   (ACSE) protocol as defined by ISO 8650 or ITU X.217/X.227, the
+   lower ISO Presentation Layer as defined by ISO 8823/ITU X226, and
+   the ISO Session Layer as defined by 8327/ITU X.225.
+
+* *jositransport* - implements RFC 1006 and the OSI Transport Service
+   Layer.
+
+
+== Using OpenIEC61850
+
+The easiest way to learn how OpenIEC61850 works is by running and
+analyzing the console client and server applications. You might want
+to look at the source code of the console applications to get an
+understanding of how they work. They can be used as a basis for you to
+code your individual client or server applications.
+
+An IEC 61850 device that is to be controlled or monitored is called an
+IEC 61850 server. An IEC 61850 server normally listens on port 102 for
+incoming connection requests by IEC 61850 clients.
+        
+=== Client
+
+If you want to connect to an IEC 61850 server, you should first create
+an instance of ClientSap (SAP = Service Access Point) and configure it
+to your needs. Then you build up the association to the server using
+the associate() method.
+    
+=== Server
+
+First get a List of ServerSaps using the method
+ServerSap.getSapsFromSclFile(). This method reads in the SAP from the
+given ICD file. Take the ServerSap you want to run and configure it to
+your needs (e.g. set the port to listen on). The ServerSap includes
+the complete device model defined in the ICD file. Retrieve a copy of
+it using the method getModelCopy(). Tell the ServerSap to start
+to listen on the configured port using startListening(). This is a
+non-blocking function.
+
+=== Data Model
+
+An IEC 61850 server contains a treelike data model that contains at
+its leafs the data (integers, boolean, strings etc) that can be
+accessed by clients. Clients can also retrieve the whole data model
+from the server.
+
+The upper most model node ist called "server". In OpenIEC61850 it is
+an object of type ServerModel. The server node contains 1..n logical
+devices (LD). A logical device may contain 1..n logical nodes (LN). A
+logical node may contain 1..n data objects. In OpenIEC61850 the
+logical nodes do not contain complete data objects but instead contain
+so called functionally constraint data objects (FCDO). An FCDO is a
+data object that is split up by functional constraint. An FCDO can
+contain a combination of other FCDOs, arrays, constructed data
+attributes and/or basic data attributes.
+
+All nodes of the server model in OpenIEC61850 are of one of the
+following seven types: 
+
+* ServerModel
+* LogicalDevice
+* LogicalNode
+* FcDataObject
+* Array
+* ConstructedDataAttribute
+* BasicDataAttribute
+
+They all implement the ModelNode interface. The nodes FcDataObject,
+Array, ConstructedDataAttribute and BasicDataAttribute also implement
+the interface called FcModelNode because they are considered
+functionally constraint data in the standard. Many of the services of
+IEC 61850 can only be applied to functionally constraint data
+(e.g. GetDataValues and SetDataValues).
+
+When programming a client you get a copy of the server model either
+through ClientAssociation.retrieveModel() or
+ClientAssociation.getModelFromSclFile(). When programming a server you
+get a copy of the server model through the ServerSap.getModelCopy()
+function.
+
+You can then navigate through the model using several functions:
+
+* ServerModel.findModelNode(ObjectReference objectReference, Fc fc)
+  will search for the subnode with the given reference and functional
+  constraint.
+
+* ModelNode.getChild(String name, Fc fc) will return the child node
+  with the given name and functional constraint.
+
+* ModelNode.getBasicDataAttributes() will return a list of all leaf
+  nodes (basic data attributes) of the model node.
+
+    
+    
+== Modifying and Compiling OpenIEC61850
+
+We use the Gradle build automation tool. The distribution contains a
+fully functional gradle build file (_build.gradle_). Thus if you
+changed code and want to rebuild a library you can do it easily with
+Gradle. Also if you want to import our software into Eclipse you can
+easily create Eclipse project files using Gradle. Just follow the
+instructions on our
+link:https://www.openmuc.org/faq/gradle_getting_started/[FAQ site].
+
+== IEC 61850 Concepts    
+    
+=== Data Sets
+
+Data sets (DS) form a group/set of data. Data sets can be used to read
+or write several data objects/data attributes at once using a single
+request/response message exchange. The service used for this are
+GetDataSetValues and SetDataSetValues. Besides the data set
+services the reporting, logging, GOOSE and sampled value services also
+use the data set concept.
+
+The data attributes or data objects that are part of a data set are
+called the members of a data set. Only functionally constraint data
+may be a member of a data set.
+
+The IEC 61850 standard defines five ASCI services related to data sets:
+
+* *GetDataSetValues* to get the value of all members of the data set.
+
+* *SetDataSetValues* to set the value of all members of the data set.
+
+* *CreateDataSet* to create a new data set dynamically.
+
+* *DeleteDataSet* to delete a data set that was created.
+
+* *GetDataSetDirectory* to get the list of all existing data sets in
+   the server
+
+Two types of data sets exist:
+
+* *Persistent data sets* - they have a reference of the format
+   LDName/LNName.DataSetName . They are visible to all
+   clients. Persistent data sets can be preconfigured in the SCL
+   file. In this case they cannot be deleted. Persistent data sets can
+   also be dynamicall created by clients. In this case they may be
+   deleted again later. Dynamically created data sets will be
+   automatically deleted once the server stops.
+
+* *Non-persistent data sets* - they have a reference of the format
+   @datasetname . They are only visible to the client that created it
+   through the CreateDataSet service. These data sets only exist as
+   long as the association is open.
+
+
+=== Reporting
+
+Reporting allows a server to send data based on events and without
+explict request by the client. What data is sent and the events that
+cause reports are configured through so called report control blocks
+(RCB).
+
+The standard distinguishes between two types of reporting: buffered
+reporting and unbuffered reporting. With buffered reporting reports
+are buffered by the server in case a connection to the client is
+interrupted. This way reports can be sent after the client has
+connected again. Buffered reporting is configured through buffered
+report control blocks (BRCB). Unbuffered reporting is configured
+through unbuffered report control blocks (URCB).
+
+RCBs are located within logical nodes of the server's data model
+(i.e. the server's ICD/SCL file). They are fixed and cannot be deleted
+or added at runtime. An RCB is blocked once a client has registered to
+receive reports (by enabling it). That means a single RCB cannot send
+reports to several clients in parallel.
+
+RCBs are always associated with a specific <<_data_sets,data set>>
+that must be located in the same logical node as the RCB. A subset of
+the data set's members will be reported if any of the configured
+events occures. The associated data set of the RCB can be
+dynamically changed by a client at run-time.
+
+RCBs are located in logical nodes in the server's model tree. Therefor
+the reference of an RCB is of the form
+LogicalDeviceName/LogicalNodeName.RCBName . Even though RCBs can only
+reference data sets located in the same logical node as the RCB
+itself, they can still monitor data from other logical nodes because
+the data set's members can be located in other logical nodes.
+
+The following events can cause a server to send a report:
+
+. The client issues a general interrogation. 
+
+. A data attribute that is part of the associated data set changes or
+is updated.
+
+. Periodic sending of reports has been enabled by setting the
+integrity period of an RCB.
+
+Whether one of these events really causes a report to be sent is
+configured through the RCB.
+
+A report control block contains the following fields:
+
+* Configuration fields. They can only be written if the RCB has not
+  been enabled nor reserved by another client:
+
+** *RptID* - The report ID identifies the RCB. If not set, it equals
+   the RCB reference. The RptID will be sent with every report so that
+   the client can identify the RCB responsible for the report.
+
+** *DatSet* - The reference of the data set associated with this RCB. It
+   must be located in the same logical node as the RCB. Members of
+   this data set will be reported whenever the configured events
+   occure.
+
+** *OptFlds* - A bitstring where each bit indicates whether an
+   optional field is included in the reports caused by this RCB. The
+   following optional fields exist: sequence-number, report-
+   timestamp, reason-for-inclusion, data-set-name, data-reference,
+   buffer-overflow, entryID, segmentation, and conf-revision. For
+   URCBs the values of buffer-overflow and entryID are ignored.
+
+** *BufTm* - In case of an event that causes a report the server will
+    wait for _BufTm_ ms for other events. All data that is to be
+    reported because of events in this time span is sent in a single
+    report.
+
+** *TrgOps* - Specifies which events will trigger reports. Possible
+    events are:
+
+*** data change (dchg)
+
+*** quality change (qchg)
+
+*** data update (dupd)
+
+*** integrity - if enabled the server will send periodic integrity
+    reports to the client. Integrity reports will contain the current
+    values of all members of the referenced data set.
+
+*** general interrogation (GI).
+
+** *IntgPd* - The integrity period specifies an interval in ms for the
+    periodic sending of intergrity reports. 
+
+** *PurgeBuf* (only part of BRCBs not URCBs) - 
+
+** *EntryID* (only part of BRCBs not URCBs) - 
+
+* Information fields: can only be read:
+
+** *SqNum* - the current sequence number of the RCB. After sending a
+   report the RCB will increment the sequence number by one.
+
+** *ConfRev* - The configuration revision is a counter representing the number of
+   times the referenced data set was changed.
+
+** *Owner* - Shall be equal to the IP of the client that reserved the
+    RCB. Shall be NULL (i.e. the empty string) if the RCB is not
+    reserved.
+
+** *TimeOfEntry* (only part of BRCBs not URCBs) 
+
+* Functional fields: The following fields of the RCB can be read or
+written to execute functions:
+
+** *Resv* (only part of URCBs not BRCBs) - Before doing anything with
+    an RCB a client should reserve it by setting this field to
+    true. If the setting was successful the RCB will be reserved
+    exclusively for this client. Enabling an RCB that has not been
+    reserved implicitly reserves it.
+
+** *ResvTms* (only part of BRCBs not URCBs) - This attribute of BRCBs
+    is optional. If not present the control block is reserved by
+    simply enabling it. A ResvTms value of -1 indicates that the
+    control block was reserved by configuration for a certain set of
+    clients. A value of 0 indicates that the BRCB is not reserved. A
+    client can reserve the control block by writing a value largen
+    than 0. The value represents the number of seconds that the
+    reservation shall be maintained after the association was closed
+    or interrupted.
+
+** *RptEna* - By setting this variable to true reporting will be
+    enabled. Note that changing/writing and configuration fields of
+    the RCB will fail as long as reporting is enabled.
+
+** *GI* - General Interrogation. Setting this parameter to true will
+    initiate a report to be sent to the client. This report will
+    contain all the data of the associated data set. The GI parameter
+    will be reset to false automatically by the server once the report
+    has been sent.
+
+
+A report always contains the following information fields:
+
+* *RptID* - The report ID identifies the RCB that has caused the
+   generation of the report. It equals the RptID field of the RCB.
+
+* *OptFlds* - It is equal to the OptFlds field of the corresponding
+   RCB.
+
+* *SqNum* (optional, included if OptFlds.SequenceNumber is true) - The
+   sequence number of the report. It is equal to the SqNum field of
+   the corresponding RCB by the time it was sent.
+
+* *TimeOfEntry* (optional, included if OptFlds.report-timestamp is
+   true) - specifies the time when the Entry ID was created.
+
+* *DatSet* (optional, included if OptFlds.dataset-name is true) - The
+   reference of the data set whose data is sent in this report.
+
+* *BufOvfl* (optional, only included if it is a buffered report and
+   OptFlds.buffer-overflow is true) - Indicates the server lost report
+   entries due to a buffer overflow. Only applies to buffered
+   reporting.
+
+* *EntryID* (optional, only included if it is a buffered report and
+   OptFlds.entryID is true) - Entry identification ToDo
+
+* *ConfRev* (optional, only included if OptFlds.conf-rev is true) - It
+   is equal to the ConfRev field of the corresponding RCB.
+
+* *SubSqNum* (optional, included if OptFlds.segmentation is true) - In
+   case that a long report does not fit into one message, a single
+   report shall be divided into subreports.  Each subreport shall have
+   the same sequence number and a unique SubSqNum.
+
+* *MoreSegmentsFollow* (optional, included if OptFlds.segmentation is
+   true) - indicates that more subreports with the same SqNum follow.
+
+* *Inclusion Bitstring* - A bit string whose length equals the number
+   of data members of the referenced data set. Each bit indicates
+   whether the corresponding data member is included in the report or
+   not.
+
+* *Data-references* (optional, included if OptFlds.data-reference is
+   true) - The references of the reported data set members.
+
+* *Values* - The values of the reported data set members.
+
+* *Reason Codes* (optional, included if OptFlds.reason-for-inclusion
+   is true) - The reason codes indicate for each reported value, the
+   reason why it was reported. Possible reasons are data change,
+   quality change, data update, integrity, general interrogation,
+   and application trigger. Several reasons can be true for a single
+   reported value.
+
+A client that wants to receive reports from a certain RCB would
+usually first attempt to reserve the RCB. If successful he would then
+configure the RCB as he wishes. Finally he would enable reporting.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
