I’d say that WikiData is almost implied by the fundamental flaw of DBpedia;  since DBpedia is based on parsing inexact and varied markup,  there is a lot of complexity in getting the accuracy high,  particularly in the problem that it’s hard to interact with Wikipedia with an automated system to fix problems efficiently.  DBpedia Live was a step in the right direction,  but you still have to deal with stability of identifiers problems that have come up in another thread.

 

   WikiData was ambitious project and it has been pulled off well.

 

   A big impact I see from it is that I’m not happy with the concept that wikipedia-en is the Universe anymore,  and WikiData will help with that.  For instance,  there are pretty places in Portugal that are not documented well outside that language area – despite the fact that tourists could get there easily from the en, fr, nl, de, etc. zones.  Similarly,  news agencies and bibliographers will benefit from better coverage.  Perhaps they’ll find the bus stops excessive,  but they are a must for the Hitchhikers’s Guide to the Galaxy.

 

   Fully integrated with Wikipedia,  WikiData will also improve the coverage of all the Wikipedias since will be easy to link up content.  It’s exciting.
