NOTE: We are still using Protege 3.X although there is a new release of  4.0 which we have been exploring. NIFSTD ontologies are loadable and viewable in Protege 4 but it runs into some issues while saving them using this version. Protege 3.X uses RDF/XML whereas 4.0 is using OWL/XML. This theoretically will create less bugs and issues, but we aren't totally there yet. (Something just to note) We have been using OWL 1 and Protege 4 is using OWL 2.

Loading Specific NIF Module(s)

The current NIF owl modules with their URLs PURLs are listed below.

 

  1. Open Protege and select New Project
  2. Click the checkbox for "Create from existing source" and highlight "OWL/RDF Files"
  3. Load NIF-BACKEND (http://purl.org/nif/ontology/Backend/nif_backend.owl) which contains all the upper level ontologies and annotation properties
  4. In Metadata tab locate the ontology browser on the left and click the first button on the top (mouse over the button says "Import Ontology...")
  5. Select "Import an ontology from the web by specifying the http:// ... URL"
  6. Enter the URL of the NIF module you wish to view
  7. Repeat step 4 to 6 if you want to view additional module(s) together
In order to view the rdfs:label of classes and properties (aka, the recognizable names and not the IDs):
  1. Click on Forms tab
  2. Under OWL menu, navigate to Preferences
  3. Under Visibility tab, click "All" under Metaclasses and then close window.
  4. In the Forms tab, you will see owl:Thing and then rdfs:class and rdf:Property. For the following, you will change the display slot in the form editor (just to the left) to "rdfs:label"
    1. rdfs:Class
    2. owl:Class
    3. owl:DeprecatedClass
    4. rdf:Property
    5. owl:DatatypeProperty
    6. owl:ObjectProperty
  5. If you wish, you can go back to the visibility tab and uncheck "all" but that is up to you.
  1. Select File-->Preferences..--> Renderer
  2. Under 'Entity rendering', select 'Render by annotation property' (e.g., rdfs:label, skos:prefLabel)

Now you will be able to view all the preferred labels for both classes and properties.
