Ah - I think that is why I put it in - to see what happened :-)
I was thinking of putting a Class in as well, but I guess that makes less difference.

Sorry, I wouldn't dare - I am more of a parasite, feeding on the hard work of people who do the standards service.
And my apologies to people who are having severe indigestion at the example I used, as opposed to encoding it properly in RDF.

A number of years ago I proposed an approach to a solution I called Instance Markup Language (1) which gained no traction. The consensus at the time was that RDFa would provide the solution for this need and also that it wasn't really important because the great bulk of instance data would come from large data bases and not from HTML. I don't think RDFa has in fact provided a "clean and simple" way to identify specific terms in HTML text and link those terms to classes or properties in a specific ontology. I never thought my proposed approach was exactly right, but I did have hope it would inspire someone come forward with a similar, but cleaner, way to do this. Even though the subject still occasionally come up, after all these years it's pretty clear I was wrong about this
