[Registry-dev] Triples

[Paul Fremantle]

Tammo

I'm afraid this article slightly misrepresented the Registry! We 
mentioned triples in passing to Rich and he seems to have expanded on 
the theme a little.

We do support a general model of "associations" which are in effect 
triples. The association model is 
ResourceURI->associationTypeURI->OtherResourceURI

For example we use this to implement our dependencies in the Registry. 
This is a first step in using this model to add semantic information, 
and so at the moment there is not extra stuff for using SAWSDL, OWL-S, 
etc. However, we *strongly* believe we have the infrastructure in place 
to support these - it is simply a matter of adding the right extensions. 
For example, the WSDL support we have is completely based on open 
extension points.

I hope this makes it clearer.
