How do bases relate to the rest of Freebase?
The collection of user-created bases is a very important part of Freebase as a whole. The other part of Freebase is the Freebase Commons. The Freebase Commons is a collection of over 4 million topics that users can draw from when they’re creating a base. These topics are grouped together by subject so that they’re easy to browse. The Film Commons, for example, contains nearly 300,000 topics related to the movie industry, and the Business Commons contains 725,000 topics on companies, board members, and other business related subjects. Over time, the community will promote the highest quality bases to the Freebase Commons so that anyone can reuse and add to them.
