Web 2.0 commentators such as Mike Arrington, and as mentioned above,Tim O'Reilly, both blogged about the imminent release of Freebase earlier today. Although I haven't looked at this database yet, it is crystal clear to me that it is one of many Web Databases to come. Others that I am personally familiar with, and involved in, include: DBpedia (Wikipedia as a true Database) and Zitgist (soon to be unveiled).

All of these databases mark the crystallization of the "Data Web" and the imminence of what is increasingly referred to as Web 3.0.

I certainly hope that all web 3.0 Database Providers keep the data Open, adhere to Web Best Practice recipes for sharing and publishing data, and generally make the process of data, information, and knowledge discovery via the Web much easier.
