I think our own wikibase could be used to give a more structured semantic meaning of tags, and combinations of tags.
For example, we want to define what a McDonalds restaurant is in our database. Is it a node with name=McDonalds? Well, a parking lot could be named the same. Is it a way with amenity=fastfood + name=McDonalds? Well, in China they are called differently. Is it a relation, node or way with franchise:wikidata=Q38076? What combination of tags is enough to be sure that something is a McDonalds restaurant? We have to define that somewhere. Well, this wikibase would be a database of all these combinations that can be considered to have a specific meaning. Then those items could be connected with Wikidata or other databases. Also, dataminers would have a reliable place with defined queries for their needs. But this is a bit offtopic.
