This document is a draft set of standards and recommendations for the observatories. The national Urban Observatory MUST adopt a degree of unanimity in the way it presents data, to allow either a single entrypoint API, or a capable client, to negotiate data from all the observatory locations, and thereby performing meaningful comparisons and analysis.
You can view the most recent draft on this page. You will find most of the detail that has yet to be incorporated into the document under discussion in this list of outstanding issues.
All vocabulary terms and the ontology for collections, filtering and hypermedia are defined in the uo namespace. Additional guidance and requirements for adding terms to the pan-observatory vocabulary is provided on this page.
