Most common problem - The plug-in's JAR file was improperly constructed. JavaSoft's "jar" command can be confusing so it's relatively easy to produce a bad JAR file. Since JAR files are packaged using the ZIP file format, you can examine them with any utility that allows you to view ZIP files. On the Windows platform, for example, you can use the WinZip utiltity. Look at the relative pathname entries for your plug-in's classes. If your class FancyWidget is in a package called "edu.

Yes, the Mayo Clinic has done this. They have instructions on their Web site about how to embed Protégé within Eclipse.

Protégé is an extensible, platform-independent environment for creating and editing ontologies and knowledge bases. In the overview section of our Web site, you'll find screenshots of various sections of the User Interface, a more detailed description of the functionality offered, and example projects that run inside of a Web browser.

The primary reason for a mentoring relationship is to help the protégé with his or her personal and/or professional development. The Protégé Development Plan is the main document to formalize the specific objectives of the relationship. (Source: The Complete Guide to Mentoring and Coaching) Ingage uses the Protégé Development Plan as a working document between the mentor and protégé.

The matching of the mentor and protégé is initiated by the protégé. The protégé first reviews a selection of mentor profiles on the Ingage web site, and then chooses the mentor they believe will best help them to reach their personal and professional development goals.

HHS is currently evaluating the feasibility of implementing a Mentor/Protégé Program. We do not currently have a program in place. Should the framework of the program be established, a notice would be issued in the Federal Register and FedBizOpps to inform the public and obtain comments

Pellet comes with a DIG server that you can use with Protégé. You can start the DIG server by running pellet-dig.bat on Windows systems and by running pellet-dig.sh on Unix-like systems. You need to make sure that the port number used by Pellet and Protégé is the same. When Pellet DIG server start you will see a message like the following: In Protégé, go to "OWL" menu and select "Preferences".

If they are at a participating campus, please direct them to our web site. In addition, you could forward to them a 'Call to Students' email message, which we have posted on our web site so you can copy and paste it directly into an email message. Please feel free to forward this message to students or place the message on a distribution list of students who are eligible and might be interested in applying as a protégé.

See the documentation section of the Protégé Web site for available documentation. Among other things, you'll find the Protégé User's Guide, a "getting started" tutorial, and information on ontology development.

Protégé supports knowledge base entry in any language or character set but the tool itself is only offered in English.

Yes, Protégé can be run as an applet. We provide examples of this in the overview section of our Web site. Go to the Project | Configure... menu. On the "Tab Widgets" panel, check the box next to the name of the tab widget plug-in you'd like to see in your project.

See the documentation section of our Web site for some (minimal) design documentation. Of interest is the section entitled "Design Rationale" on our user documentation page that describes the design decisions most often asked about. Developers may also be interested in the documentation of the Protégé Programming Development Kit on our developer documentation page.

You don't need to sign anything to download, use, or redistribute Protégé. This includes academic, government, and commercial users.

The Protégé-OWL editor is bundled with the "full" installation of Protégé. If you are only interested in creating OWL ontologies, you may choose the "Basic + OWL" option during the install process. Choosing this option will install the core Protégé system, the Protégé-OWL editor, and only those plug-ins that work with OWL ontologies, e.g. OWLViz, OWLDoc, etc.

What the mentoring would involve would be to take you through this whole process step-by-step. A business development manager would give you instructions/assignments/worksheets. For instance the third module is about developing a solution that solves your niche market's compelling problems. From the online research you will have done into your market you will already know the compelling problems faced in that industry ..

Everyone has something to offer as a mentor. Do you have a field that you specialize in or an area that you have excelled in? As long as you have a sincere want and willingness to give back and to foster the personal and professional growth of others, we will provide you the training necessary to become an excellent mentor. We train and certify all of our mentors through our Ingage Mentor Training program.

MentorNet was developed to leverage electronic communications in order to connect people who are in different locations and who abide by different schedules. So, frequently mentors and protégés will never meet face-to-face, yet can develop effective mentoring relationships.

Protégés are recruited through our campus representatives who get the word out through email, by putting up posters or flyers, by visiting meetings of students chapters of professional societies, and by encouraging faculty to let students know about the opportunity. Protégés also learn about MentorNet through alternative means, such as school newspapers, Internet articles, and current or previous MentorNet participants.

Bugs that are specific to the Protégé-OWL editor should be reported on the protege-owl mailing list. All other bugs should be reported on the protege-discussion mailing list. You can view the current bug list and feature request list in Bugzilla.

Yes. There are PDF versions of both the User's Guide and the Getting Started tutorial in the documentation section of our Web site.

You may use the following, simple procedure to subscribe to any of the four Protégé mailing lists: Go the the list information page for the list that you would like to join (links to list information pages: protege-users, protege-owl, protege-discussion, protege-beta). Important: After you click the Subscribe button, you will receive an email asking you to confirm that you really want to subscribe to the list.

Protégé runs on pretty much any platform that supports JDK version 1.4. This includes all modern versions of MS Windows (NT/2000/XP), the common versions of Unix including Linux, Solaris, AIX, and HP-UX, and on the Mac OS X.

If you launch Protégé from somewhere other than the installation directory, you must specify the Java property "protege.dir". For example, if you installed Protégé in "C:\Program Files\Protege_3.1", you would type the following on the command line: java -Dprotege.dir="C:\Program Files\Protege_3.1" -jar "C:\Program Files\Protege_3.1\protege.jar"

Protégé doesn't provide direct support for this, but it can easily be done. Web Protégé is an example of how to do this via Servlets.

Protégé does not have built in support for synonyms. One way to represent synonyms is through the use of metaclasses. Create a metaclass with a slot called "synonym" and then create instances of this metaclass. You can find more information about using metaclasses in our User's Guide. There are also two pages on the Protégé Wiki that may be of interest to those researching support for synonyms:

A team at SRI International released an alpha version of a DAML+OIL back-end for Protégé-Frames.

Protégé supports any database that has a JDBC 1.0 driver. In practice, this means most relational databases. We have direct experience working with Oracle, MySQL, Microsoft SQL Server, and Microsoft Access. We provide information in our User's Guide about saving projects to a database. There's also an explanation of our database structure in the documentation section of our Web site.

Yes. You can use the OKBC Tab plug-in to import and export Ontolingua ontolgies in Protégé. You need to append the string ";SelectMethod=cursor" (without the quotes) to the end of the JDBC URL. Thanks go to Neil Earnst for providing this information and a more detailed description on the CHISEL Web site. The schema was not designed to be usable by external applications. It is more or less optimized for Protégé's internal purposes.

The Protégé API is only available in Java. You can access Java APIs from C and C++ using the Java Native Interface (JNI). The JavaSoft website and most intermediate/advanced Java programming books provide usage examples.
