[OHM] temporal data in the OHM sandbox

[Jeff Meyer]

Erik -

Solving small problems with historical mapping is what this project is all
about!

I have no doubt that others share your exact concerns and face the exact
same challenges.

What are the specifics of these problems and how can we start hammering
them out?
If it's just the tagging concerns below, maybe we should just start
building out OHM tagging practices pages on the wiki and see how they
emerge?

I'd also be interested in anyone's thoughts about starting to integrate
schema.org-type descriptions or integrations into our tagging.

Thanks,
Jeff
