[open-bibliography] Extra RDF datatypes

[Christopher Gutteridge]

I deliberately hosted it via purl.org so that if needed it can be taken 
on by a group to develop. I'm aware of all the potential niggles about 
versions but IMO this is over engineering. I want a system which can 
tell me if something is plain text (not marked up at all), or some 
flavor of HTML.

Beware the siren call of The Modeller.

In xtypes you can specify something as a subclass if you really must, eg.
http://purl.org/xtypes/Fragment-LaTeX-2.1.23.ourSpecialVariation

But I think trying to formalise URIs for not only every version of these 
fragments, but every controlled subset... That way lies madness.
