Hi all, I didn't think I'd be answering many threads on this list but when I saw
the points about "moons of Uranus" and "cities through history"
examples I couldn't resist mentioning the LIDO Schema (
www.lido-schema.org) and the
CIDOC-CRM ontology that it's based on (
www.cidoc-crm.org/) - they have the descriptive
power and range to cope with alternative historical viewpoints and "takes" on
entities that you might need. Happy to discuss further.
