I used Freebase for about an hour now. It’s impressive how smooth some things are implemented. It’s overwhelming how big the potential is and it’s important to see how much there’s still left. And interesting to see which niche Freebase will fill in the semantic web.
Freebase brings a nice and sensible collection of so called types. And there are nice form generated to edit the type attributes of some object. But it still doesn’t feel mature. While there’s much of the data in Wikipedia available, one still feels like there are many holes and caves, where information leaks… And I don’t feel sure there’s much value in adding data. It doesn’t flow back into wikipedia, AFAIK. And there’s no immediate propagation from wikipedia to Freebase, neither… Still promising:-)
More to come
