Protégé Programming Development Kit (PDK)

The Protégé Programming Development Kit (PDK) is a set of documentation and examples that describes and illustrates how to develop and install plug-in extensions for Protégé, and how to work directly with the Protégé APIs. Plug-ins can be used to change and extend the behavior of Protégé. Protégé itself is written as a collection of plug-ins and these can be replaced singly or as a whole to completely alter the interface and behavior of Protégé. Protégé has a core API, which is used to access basic Protégé functionalities and frame-based knowledge bases (such as those created with Protégé-Frames). Protégé also has an OWL API that extends the core API to provide access to OWL ontologies (such as those created with Protégé-OWL). The Protégé API can be used directly by external applications to access Protégé knowledge bases and make use of Protégé forms without running the Protégé application.

Accessing Protégé source code
Design Rationale

Note: Developers of OWL-specific code should use the Protégé-OWL API instead of the core API. Although many of the examples below refer only to the core API, they are similarly relevant to users of the OWL API.

Accessing Protégé source code

Most users probably don't need day to day access to our source code as it changes. For these users, we provide stable versions of the source code for Core Protégé, Protégé-Frames, and Protégé-OWL in ZIP file format on the downloads page of our Web site.

The source code for Core Protégé, Protégé-Frames, Protégé-OWL, and many Protégé plug-ins is housed in a Subversion repository, which is an open-source version control system.

If you just want to browse the latest version of the code or download a few individual files, the best tool for this is the Web based ViewVC for Subversion. You may also go directly to the public repository via any Web browser: http://smi-protege.stanford.edu/repos/protege/.

If instead, you would like to download the latest version of the source code, you need a Subversion client such as TortoiseSVN. The proper URL to check out Core Protégé and Protégé-Frames source code is: http://smi-protege.stanford.edu/repos/protege/protege-core/trunk/. The proper URL to check out Protege-OWL source code is: http://smi-protege.stanford.edu/repos/protege/owl/trunk/. More detailed instructions for checking code out of our repository are provided in the Protégé Contributor's Guide (see link below).
