3.1.0

TopBraid Composer - Free Edition (and above)

- Feature: First release of the Free Edition

- Feature: Added spl:InferDefaultValue to SPIN Module Library - this can
           be used to infer default values in the absence of any other values

- Feature: Support for sp:ReversePath in constructed SPIN constraints

- Feature: Classes marked with "spin:abstract" are more difficult to
           instantiate directly, i.e. several dialogs block creating them
           to avoid common errors
           
- Feature: New SPARQL property functions:
           - tops:files for traversing files in the workspace
           - tops:split for extracting sub-strings from a (larger) string

- Feature: Improved handling of spl:defaultValue in SPIN template dialog

- Feature: SPARQL text editor now highlights unknown URI resources with a gray underline

- Feature: Added "Delete all" to context menu of property widgets

- Feature: SPIN RDF syntax now supports sub-queries
           
- Bugfix: Yellow context helper windows were sometimes outside of the visible area

- Bugfix: SPIN renderer sometimes abbreviated rdf:type with "a" in wrong places.
          
- Bugfix: Errors during species checking were not reported to the user

- Bugfix: SPARQL editor did unnecessary inferencing after each keystroke (or even
          crashed) if inferencing was turned on

- Bugfix: Better support for user-defined datatypes (instances of rdfs:Datatype or
          owl:DataRange)

- Bugfix: SPINx functions did not tolerate null arguments 

- Change: The form layout option to use rdfs:labels where possible has been removed
          because this is better handled using the global option of human-readable
          labels (in the main toolbar).
          
- Change: Default name of many wizards changed from owl-ontologies.com to example.org


TopBraid Composer - Standard Edition (and above)

- Feature: Moved to Jena 2.6 (Note: Plugin developers need to make sure that their
           extensions compile against Jena 2.6).

- Feature: Added support for Jena SDB databases - an efficient RDF database mode
           that operates on relational databases such as Oracle and MySQL. 

- Feature: Form Layout editor now indicates which type of customized form exists if no
           layout has been defined in the currently active mode.
           
- Feature: N3 writer now also orders prefixes alphabetically

- Feature: Files ending with .ttl (turtle) can also be edited directly

- Feature: Added support for spin:imports property in constraint checking.
           This property can link a file with another file that contains
           constraints, such as http://topbraid.org/spin/spinowl for OWL
           constraint checking, without having to import all of SPIN etc.
           
- Feature: Added Select... button to create restriction dialog  

- Bugfix: The export to spreadsheet features of Instances and SPARQL views did not
          consider the column sorting
          
- Bugfix: Removed unused OWL/inverse options from D2RQ import wizard 
          
- Bugfix: Workspace now uses the default namespace to guess a base URI if no xml:base
          is present in RDF/XML files
          
- Bugfix: When TDB has been activated, the NT reader stopped working

- Bugfix: Newly created nodes of the Associations view did sometimes not show up,
          unless the tree was already expanded
          
- Bugfix: The UML importer sometimes did not create owl:imports statements

- Bugfix: Adding graph edges via drag and drop did not work for union ranges

- Bugfix: Major performance improvement of browsing classes with database projects 

- Bugfix: The spreadsheet importer did not correctly import rows that had less columns, 
because they "ended" before the last column.

- Change: TopBraid Composer no longer uses customized "EditForms" - only TBE does.

- Change: Library imports now uses the official location of the D2RQ namespace

- Change: Upgraded to TDB 0.8.1 - note: existing TDBs might have to be regenerated
          as TDB has changed its internal storage format


TopBraid Composer - Maestro Edition

- Bugfix: SPARQLMotion TrackChanges module was operating on reified triples, leading
          to some very weird SPARQL interactions.
          
- Bugfix: Some SPARQLMotion modules were using default values specified for other
          properties, e.g. sml:ImportRDFFromWorkspace, leading to strange errors
          
- Bugfix: sml:ExportToRDFFile did not use URI string insertion strategy, possibly
          leading to invalid baseURIs if a string template was used.
          Furthermore, the resulting files did not contain an owl:Ontology instance
          with that base URI.
          
- Bugfix: sml:PerformUpdate sometimes failed to pre-bind incoming variables

- Bugfix: sml:ConvertXMLByXSLT couldn't convert some Unicode characters.
          
- Feature: Added an RDF comparsion/diff tool (see help How to > Compare RDF Models)

- Feature: Added two new Semantic JSP tags (see Help for details):
           - <sparql:eval expression="expr" />
           - <sparql:let var="varName" expression="expr" />

- Feature: SPARQLMotion graphs now use custom images specified using sm:icon

- Feature: SPARQLMotion scripts can now contain calls to sub-scripts.  The
           sub-scripts need to be declared as SPIN function, i.e. they can take
           arguments.  The return node of the sub-script must be encoded using
           sm:returnModule, i.e. this is the same mechanism as for SM web services.
            
- Feature: Added sml:ignoreImports flag to sml:ImportRDFFromWorkspace

- Feature: New SPARQLMotion modules
           - sml:CollectGarbage to trigger "unloading" certain files from memory
           - sml:Diff to run the (new) diff engine
           - sml:ExportToSDB to write to a Jena SDB database
           - sml:FilterByFilterGraph to suppress some triples that were previously added
           - sml:ImportSDB to read from a Jena SDB database
           - sml:PostRequest to issue POST requests to a web server
           - sml:SerializeSPARQLResults to render SPARQL results to a string
           
- Feature: Added sml:hidden option for SM web service call arguments. This will suppress
           having to enter them and instead declare them as constants (defaultValue).
          
- Feature: Added tracing support to SPARQLMotion, so that you can have the system
           print out the variable bindings whenever dedicated modules are executed
           
- Feature: The input graph to sml:TrackChanges now also contains change:graph properties
           for each statement to indicate the origin graph's URI of the change
