[redland-dev] Abbreviating URIs in XML Attribute Values

[Nicholas J Humfrey]

Hello Dave,

I do not believe that using custom XML entities in RDF/XML is very common - or at least I havn't seen it for a long time.

I am also unaware of anything in libraptor to allow you to do this.

If it is of any help, Turtle is a lot more concise than RDF/XML.
