Forwarded in case anyone's interested - Protege is an ontology tool backed by RDF (or RDBMS). It's pretty sophisticated (though lacked support for Bags last time I looked), and can be extended with plugins - the GraphViz plugin is a must. --- Danny Ayers <stuff> http://www.isacat.net </stuff> We are pleased to announce the release of Protege-2000, version 1.7. See below for a complete list of enhancements and bug fixes included in our latest release. Navigate here for the latest version: http://protege.stanford.edu/download/release/install.htm Navigate here to download and try out a number of interesting new plug-ins in our plug-ins library: http://protege.stanford.edu/plugins.html Best Regards, The Protege Team Enhancements: ---------------------- 1). A new "Welcome Dialog" is available when you launch Protege. Users can quickly open a new project, reopen a project from a most recently used list, or click one of several help buttons to access our User's Guide, FAQ, and tutorials. You can turn off the "Welcome Dialog" if so desired on the Project->Configure...->Options tab. 2). The Project menu contains a new menu item called "Open Recent" which displays a list of the most recently used projects. 3). You can now run Protege from the command line using the command: java -jar protege.jar. 4). Form customizations of a class are now automatically "inherited" by subclasses. Previously you had to do a manual "customize subclasses" step with the consequence that your .pprj file could become quite large. This is no longer necessary. Instead the "customize subclass" right mouse item has been replaced with "remove subclass customizations". 5). The RDF backend now supports user defined facets as well as preserving "yellow stickies" and pal constraints. 6). For the JDBC backend there is now a way to specify the string used to create the LONGVARCHAR data type. Previously the system queried the driver and used the data type name in a CREATE TABLE call. Some systems (DB2) require a size for this parameter and the only way to get protege to work with these databases was to recompile the source. Now the entire datatype name can now be specified as the value for a java property "SimpleJdbcDatabaseManager.longvarcharname". The best way to set this variable is by setting the corresponding value in the protege.lax file. Note that you do not need to use this for most database systems. 7). The template slots widget now sorts template slots differently. Previously all slots on a class appeared alphabetically. Now the direct slots appear first and inherited slots follow, grouped by class, as you walk up the class hierarchy. Slots are no longer sorted alphabetically, even within a group. The template slots widget can be customized to display arrow buttons that allow you to change the order of slots. 8). The Help menu in Protege is now much more helpful. Updated the Help -> FAQ menu item to point to the FAQ on our Web site rather than a page that said "to be written". Also changed the text to "Frequently Asked Questions" for the purpose of clarity. Deleted the Help -> Shortcuts menu item which displayed an HTML page that said "to be written". 9). Updated installer to now include a step which allows you to select the VM that you want to use. This is of use to those who download the "without VM" versions of Protege. 10). You can now pass a URL for a project into Protege on the command line. 11). Generate HTML now can optionally produce HTML documentation for instances. (Special thanks goes to Robert Voorn for contributing this code). 12). Modified javadoc generation so that it links back to the JDK API documentation on the javasoft web site. Added javadoc documentation to the obscure model.ValueType class methods and some of the more obscure KB methods. 14). Changed some Query tab default sizes so the default layout is nicer on small screens. 15). There is a new method on ProjectManager that allows you to keep the VM from exiting when you close the Protege application. 16). The browser text for slots is now used more consistently in the UI in place of the slot name. 17). The "About box" now credits Protege Affiliates and funding agencies. 18). The Clips backend now supports class names that contain an internal single quote character. (Names may not start with such a character however). 19). Users can now set the slot maximum cardinality to zero. Note that the API method KnowledgeBase.getMaximumCardinality() now returns -1 if the maximum cardinality is not set (previously it returned 0). 20). The value-type widget no longer accepts symbol allowed-values with spaces. These were never legal values but the widget previously allowed them. 21). Set the "contextClassLoader" in the SystemUtilities static initializer to be the class loader that knows how to load from the plugins directory. This will usually result in the "main" thread having its contextClassLoader set to this value. 22). Added a method SystemUtilities.getDefaultClassLoader() method to return the plugins directory classloader. 23). Added index on JDBC backend database table for Oracle in order to improve performance of case-insensitive search. Plug-in Enhancements: --------------------------------- 1). Removed built-in XML parser from rdf-api.jar and configured the system to use the Xerces XML parser (version 1.4.4). 2). Modified the XML DTD and XML Schema backends in the plug-ins library so that they both use the same version of the Xerces XML parser. Repackaged these XML backends so that Xerces is an external JAR rather than included in the backend JAR. 3). Added some missing class to the PAL distribution. PAL now comes as two jar files that need to go into the plugins directory: pal.jar and antlr.jar. 4). Added hook to several widgets to enable tab widgets to capture the "double click" operation. Bug Fixes: --------------- Removed references to missing tabs at project load time. This also results in only "real" tabs showing up in the Project | Configure dialog. Fixed incorrect error message in "Warnings" panel on InstanceRowWidget. InstanceTableWidget and InstanceRowWidget no longer allow you to delete instances from included projects. Fixed a long standing problem that caused the database back-end to sometimes print out "duplicate frame id" error messages after the user creates frames. Thanks go to Daniel Rubin for providing a reproducible test case for this problem. Fixed a performance problem in the database back-end when talking specifically to Oracle RDBMS. Incorporated a fix from Michael Sintek for the RDF back-end concerning references to slots in included projects. Fixed problem that caused FormsTab to not update when forms are changed programmatically. Fixed a regression in the clips parser that caused exceptions when double quote characters were encountered in frame names. The "standard text" (clips) backend now accepts unicode escape sequences. This change addresses the problem that caused load-time failures with error messages that look like Lexical error at line N, column M. Encountered: "\u2019" ... Fixed bug that caused the clips backend to incorrectly handle strings which terminate in a "\". Fixed a bug that allowed a user to change the override of facets on included classes. Fixed a bug that caused hidden classes from included projects to behave incorrectly. Fixed a bug that caused cardinality multiple template slot values to multiply like rabbits in instances. Removed dead code that supported a very old version of the RDF backend. The database backend now works correctly with MS Access again. The Windows "Look and Feel" now displays included classes in the classes tree more clearly. The Welcome Dialog now remembers the opened project if you exit Protege by closing the console window. The "New" button on the "Welcome Dialog" now works correctly. Removed some unused menu items and tool bar buttons. Fixed the "Project | Include" menu item which did not result in included projects being set up correctly. (This wasn't a problem for previously included projects, just new ones.) Fixed a problem wherein the project files grew without bound with each save. Fixed a problem wherein setting a template slot value for a slot would cause existing own slot values for that slot to not be displayed anymore. ------------------------------------------------------------------- --- To unsubscribe, send email to majordomo@smi.stanford.edu with "unsubscribe protege-users" in the message body (no quotes).
