Protégé-2000 1.9 Release Notes

Release date: August 8, 2003
Download URL: http://protege.cim3.net/download/old-releases/1.9/

Release Highlights

Protégé now requires JDK 1.4.
The standard Protégé installation no longer comes with the Xerces 1.4 XML parser. We now use the Java API for XML Processing (JAXP) specification and Crimson parser implementation that are bundled with JDK 1.4. If you install version 1.9 without without uninstalling older versions, you should delete the xerces.jar file from your plugins subdirectory to avoid XML parser conflicts. If you want to use a plug-in that requires a different XML parser, there are a couple of steps to perform to avoid parser conflicts. In the jre/lib directory of your JDK 1.4 installation, create a new subdirectory called endorsed. Move your XML parser JAR file from the Protégé-2000/plugins directory to the jre/lib/endorsed directory. If you are curious, this rather strange procedure is explained in more detail by Sun.
The diagram widget is read-only in this release and will be removed entirely in the next release. Please update your projects to use the graph widget. General documentation for the graph widget, as well as conversion instructions are available on our Web site.
We removed the RDF back-end from the standard Protégé installation. It is now available for download from our plug-ins library

Enhancements:

Added a Remove ("-") button to the graph widget to allow removal of nodes.
Updated the graph widget to allow user-defined colors for nodes, node text, and connectors.
Added the ability to hide label text on simple connectors in the graph widget.
Added the ability to create reified relations outside of the graph widget and then have them show up in the graph.
Added a method to the GraphDocument class called "getNodeRectangle()" that allows programmatic access to node position in the graph widget.
Deleting simple connectors in the graph widget using the Delete button/key updates the list of own slot values on the source node's connector slot.
Projects can now be loaded from a JAR file.
Added a "copy" button to the direct instances list on the Instances tab. You can make either shallow or deep copies. (Contributed by Vsevolod Ilyushchenko).
Added capability to create a new instance from the template slots value and default value widgets.
Added a hook to AbstractSlotWidget to allow a user to catch calls to "showInstance" (the "V" view button) and do something special with them.
Added a property to the Protege-2000.lax file called "UMLSTab.dbyear" that allows users to specify the release number of Metathesaurus data to query in the UMLS Tab.

Bug Fixes

For HTML generation, removed links to instances from class HTML page when instance HTML pages are not generated. (Contributed by Samson Tu).
For HTML generation, removed the phrase "Class slot documentation: " from slot documentations. (Contributed by Samson Tu).
For HTML generation, gave class documentation appropriate heading. (Contributed by Samson Tu).
Fixed various javadoc warnings.
Fixed problem that caused the CLIPS backend to not save slot constraint constraints.
On Mac OS X, Protege now launches with the correct version of the VM (which is 1.4 and above).
Fixed HTML generation to write out the correct encoding (usually UTF-8).
Fixed RDF backend to write out the correct encoding.
Fixed a problem with highlighting of nodes and connectors in some circumstances in the graph widget.
Fixed a problem on the slots form that caused buttons on the default-values and template-slot-values widgets to be disabled inappropriately at times.
Incorporated a fix for a problem with recursive inclusion not being detected in some situations. Thanks go to Thiru Vidai for sending us this fix.
Fixed Graph Widget bug so that text editing on node and reified relations labels when the :NAME slot is the form browser key now works.
Fixed Graph Widget bug so that the Remove ("-") button is no longer enabled on instances of the Graph Widget in included projects.
Fixed a problem that caused the system not to be able to load a file based project after loading a project from a jar.
Fixed graph widget bug so that text of reified relations is now updated when users change this value via an instance form.
Fixed a problem with window positioning on systems with virtual screen capabilities.
Fixed a problem that occurred when a slot has both template value and default value specified. Now the template values "win".
Fixed a problem that caused a stack dump when a change to a template slot value was canceled.
Fixed a problem that made it impossible to override the allowed-classes in some situations.
Fixed a problem that caused the system to only recognize projects in jar files when they are passed in on the command line (and not, when passed in programmatically through a call to "new Project()").
Fixed graph widget so that adding an own slot value to a node's connector slot via an instance form now updates the graph's display.
Fixed graph widget so that removing an own slot value from a node's connector slot via an instance form now updates the graph's display.
Fixed a problem which caused the application to crash if you included a project in itself.
Worked around JDK 1.4 problem that caused tabs to get "shown" events when the project is closed.
Fixed problem with PAL constraints in the Newspaper example.
Fixed problem with overriding class-type template slots so that only "narrowing" operations are now permitted.
Fixed a problem with the template slot value and default values widget not allowing a value to be entered in some situations involving overriding.
Fixed problem with generated HTML documentation slot.
Fixed a problem with KnowledgeBase.hasDirectlyOverriddenTemplateSlot().
Fixed some problems with the return values from several of the facet override testing methods on knowledge base.
Fixed a problem with cardinality single slot widgets displaying template slot values in some cases.
Fixed a problem which caused the template and default values slot widgets on overridden slots to allow incorrect values.
Fixed a problem that sometimes caused text own slot values to not get updated in the KB after they were changed on a widget.
Fixed a problem with "create slot using metaclass" menu item not allowing a user to select a metaslot.
Fixed a problem that caused the Graph Widget to fail when slot overrides exist at the class level.
The template slots widget now pays attention to the facets on the template-slots slot.
The widget for overriding allowed classes now just allows you to narrow the selected class.
The Frame.setName() call now generates an OWN_SLOT_VALUE_CHANGED event for the :NAME slot.
Long slot widget labels no longer appear on top of the buttons for the widget.
