Creating a Project

There are two ways to create a new Protégé-2000 project:

Creating a Project When You Start Protégé

To create a project when you start Protégé:

  1. Start Protégé. 
    A dialog box allows you to create a new project, open a recent project, or get help.
  2. Unless you have a need for a special format for your files, make sure Standard Text Files is selected in the New Project field at the left of the window. This will create a project file in Protégé-2000 format. (See Project Structure, below, for more information about file formats.)
  3. Click New
    The Protégé window opens and the standard tabs become visible. An initialized knowledge base will be created which contains the system classes rooted in :THING. No instances will be created. You can now structure your project by creating your classes and slots. (See Creating a New Class and Creating a Slot for more information.) 
  4. To save the project to disk, select Save from the Project menu. 
  5. Enter a name for your project in the Project line of the dialog box. This is the name of your project (.pprj) file. Protégé also creates internal files for its own use. By default, these files are given the same name, with a different extension. 

Creating a Project From the Protégé Window

To create a new Protégé-2000 project:

  1. Select New from the Project menu or click the New Project button
  2. You will be prompted to save changes to the current file, if any. Click Yes to save changes, No if for some reason you do not want to modify the file (e.g., if you have been browsing or experimenting).
  3. Select the format you want for your Protégé-2000 files from the Select Format dialog and click OK.
    Unless you have a need to create files in a special format, make sure Standard Text Files is selected. (See Project Structure, below, for more information about file formats.)
  4. An initialized knowledge base will be created which contains the system classes rooted in :THING. No instances will be created. You can then structure your project by creating your classes and slots. (See Creating a New Class and Creating a Slot for more information.) 
  5. To save the project to disk, select Save from the Project menu. 
  6. Enter a name for your project in the Project line of the dialog box. This is the name of your project (.pprj) file. 

Project Structure

Each time you create a project, you are given a choice of project formats. Unless you have a need for a specific structure (e.g., for exporting files), you should select Standard Text Files. No matter which format you choose, the information specific to the Protégé-2000 interface is saved in a pprj (Protégé project) file. You can create, open, and save your projects directly via the pprj file. You do not need to name or access any other files unless you wish to import a project.

Internally, Protégé maintains two files in addition to the pprj file; these files contain further information about the ontology and instances of the project. When you open a pprj file, Protégé-2000 automatically loads these files. By default, the additional files are saved in text format:

Whenever you are creating a project, you are given a choice of formats in which these files could be saved:

If your version of Protégé-2000 has been customized to support additional formats, then you will also see them in this list.

In all cases, Protégé-2000 still uses the pprj file to access the project. You should not see a difference within Protégé.
