The following format changes were suggested by Markus:
- Ontology names should be types-specific and start with lowercase, e.g. wikibase:timePrecision
- Use separate URL/prefix for every context (we right now reuse v: in statements and references)
Also, it was suggested that we may want to change the fact that we use entity:P1234 in link Entity->Statement and give it a distinct URL. However, then it is not clear what would be the link between entity:P1234 and the rest of the data.
