I have just been watching the AllegroGraph + Amazon EC2 tutorial in which an example Ruby on Rails app is created.

Apparently Ruby has that shortcut way to handle namespaces slash vocabularies:

vocab = RDF::Vocabulary.new("http://example.com/some_domain#")
term = vocab['some_term']

The above produces a http://example.com/some_domain#some_term node. It seems useful if we want to work with full URIs.

Is there such a facility avaiable in dotNetRDF?

Thanks, Tom

Not right now, you can add it fairly trivially to generate URIs, generating actual Nodes is tricky in the current code base because Nodes are currently scoped to Graphs (this will change in 2.0)

Simple implementation:

public class Vocabulary
  public Vocabulary(String nsUri)
    this.NamespaceUri = nsUri;

  public String NamespaceUri
    get; private set;

  public Uri this[String localName]
      return UriFactory.Create(this.NamespaceURI + localName);
