Saving an RDF Project

This version of Protégé-2000 provides support for creating and editing Resource Description Framework (RDF) schema and instance data. (For more information about RDF, see http://www.w3.org/RDF.) You can use Protégé-2000 to design RDF schema and create the corresponding instance data. You can also view and edit your existing RDF files in Protégé-2000.

You can save your Protégé-2000 project in RDF format in one of two ways:

After you have chosen your format, choose the name and location for the project as follows:

  1. When you have selected Resource Description Framework (RDF), the RDF dialog box is displayed:
  2. To select or change the name or location of the pprj file, enter the information you want in the Project line of the dialog box. Be sure to give the file a pprj extension. To browse for a new location, cllick the button.  If you do not specify a location for the project, by default, the project is saved in the directory where Protégé-2000 is installed. 
  3. Protégé-2000 will create two files: one for the schema (classes and slots) and the other for the instances. By default, these use the name of the existing pprj file. If you wish to change the name of the schema file, type the new name in the Classes file name line of the dialog box. Make sure to give the file an .rdfs extension.
  4. If you wish to change the name of the instances file, type the new name in the Instances file name line of the dialog box. Make sure to give the file an .rdf extension.
  5. Enter the RDF namespace for your project in the Namespace field. All classes, slots, ad instances i the project are placed in this namespace.
  6. Click OK. 

You should create new RDF classes as subclasses of rdfs:Resource.
