I'm following discussions on several mailing lists and an idea is starting to form to help solve some of our growing pains.
I think it would be interesting to contemplate setting up our own instance of WikiData. Wikidata could then link to entries in it and vice versa for the items which are 1:1 matches. We could have dedicated entities for streets, for addresses, for PT stops and their surroundings, for PT lines. >From there we could link to objects in OSM. The problem with that is that when ways become split the editor needs to decide whether the OSMdata link is still valid. Same deal for merges. Of course, at the moment we use relations for some of these and we could create new types of relations for others, but they are deemed too complicated and they are rather fragile. Also the tendency seems to be to abolish stuff like associatedStreet and simply go the way of repeating data over and over. Or to say: do spatial queries and hope for the best. So, on the one hand I see it as a bridge to Wikidata, on the other I see it as a way to solve some growing pains we're having to maintain more and more data we're amassing. Polyglot
