Nomisma extended to link to the Getty ULAN, British Museum thesauri

This morning, the Getty Museum announced the release of the Union List of Artist Names (ULAN) thesaurus as linked open data. Following updates made to the Getty lookup mechanism in's XForms-based editing interface, I have ported these updates into Nomisma's editor. It is now possible to quickly and easily link people and organizations in Nomisma to matching concepts in the ULAN, much like what we have already implemented for linking mints and regions to the TGN and denominations, materials, manufacture methods, and object types to the AAT.

Furthermore, I took the time to finally fully implement the British Museum lookup mechanism in Nomisma. The British Museum thesauri cover many of the same broad categories as the Getty, but the main difference between the two systems is that the BM thesauri reflect what they have in their own database, and the Getty thesauri are aimed at representing concepts across all of art history. The Nomisma editing interface now enables quick and easy linking to denominations, ethnic identities, manufacture methods, materials, mints, object types, people, and regions in the BM thesauri.

See the following examples:

When creating or editing ids manually, we'll be able to easily add BM and Getty URIs into the system. Ideally we will want to do a mass update of all of our ids that can be mapped to concepts in both thesauri. Creating a concordance between Nomisma and Getty concepts will hopefully facilitate large-scale aggregation in the future.
