- Wikidata is ready as a structure to handle the cross-references of the spatiotemporal data. Adding the geopolygon datatype is needed to complete the tools.

I believe some open standards were mentioned in the discussions at Wikimania, does someone happen to have some links to these standards? Sounds like a good starting point for me.
If we have a well defined standard we like, we can implement it as a data type in Wikibase (the structured data repository behind Wikidata).
