Re: RDF Template

I am using Java but thanks for the links.

The fact that some variables can be URIs or literals is managed in the 
application itself. The template engine would get the final value of the 
variable after all necessary checking/processing needed, e.g., escape 
the literal value if needed.

The reason for such a template is that the schema can change. The data 
that is described is still the same, but its representation can change.
