Reusing Standard RDF Vocabularies - Part 1

For Project Omega at The National Archives, we are reusing existing RDF vocabularies for our new Catalogue. I examine what happens when a suitable property or class cannot be found within an existing vocabulary, and weigh-up the different approaches and compromises that may need to be made.
