The Freebase site has opened up to public access (read only) and I suggest you check it out. I have mentioned Freebase on Loomware before, especially in the context of its Semantic Web/Wikipedia aspects. From the e-mail:
Freebase.com is now in "public alpha". Anybody in the world can search and
browse the site. All applications based on the Freebase API have public read
Also, thanks to great feedback from an active alpha community, the
Freebase site has improved quite a bit, and there is a growing group
of enthusiastic contributors and developers. There is a lot of new
data -- over 30,000 films, 500,000 notable people, more sports,
businesses, science and so on.
I've been doing a lot of reading about the Semantic Web of late and thought that this posting was particularly good. One thing I like about is how it points out that there is a great deal of discussion about what the Semantic Web is and how to get there, as well as the difference between the "academic need to do it this way" and the "real world we're doing it this way" views. I also couldn't help but see this is a "fork" of the Flying Spaghetti Monster religion with all those UFO's and all :-) Transformation of the Web in action...
