This might be very interesting if it's implemented in a sane way. Unfortunately there doesn't seem to be a very widely-adopted standard in the world of open data for now..

Does the standard really matter? If it's machine understandable, it should be able to be automatically translated into any other format in the future.

The important thing is to jump in and make a start. The right way of doing things will become evident as the project evolves.

tl;dr: spin-off Wikipedia infoboxes into a seperate project with an API, and then use that data to bootstrap an open data project with broader goals. In theory, it's a good idea. It takes an existing useful data source and puts in a form that encourages reuse, and since it solves the bootstrapping problem then it's not obviously doomed to failure like the Semantic Web. I see two potential downsides. My first concern…

Is it even possible to have a database of factual content under CC-BY-SA? This is part of the reason OpenStreetMap is moving to ODbL.

Somewhat ironically , since part of the reason is that you can't copyright facts, they didn't just take the existing data under the same theory, but asked everyone to accept the new licence. I wonder what Wikipedia plan to do?

Hats off to Wikimedia, a beacon of the true ideals of the free Internet; they've never tried to monetize their substantial achievements, really made a difference, and actually realized what for other companies have been merely lip service (i.e. freeing up information).

Missing from the FAQ: What's the difference between Freebase and Wikidata?

It looks like the main difference is two-way integration: instead of just scraping data from Wikipedia dumps to produce a structured database (like Freebase and dbpedia do), it's going to store the canonical version of some of the information there, and pull from it to populate the infoboxes. One of the motivations seems to be to keep the data in sync across Wikipedia languages, so an addition or fix propagates to them all, which is currently done somewhat awkwardly by a mix of manual and bot measures.

For people interested in this subject, you might want to check out the DBPedia project: http://dbpedia.org/About. They have been extracting structured data from Wikipedia for quite some time already and allow you to query their database with SPARQL.

From their site: The DBpedia knowledge base currently describes more than 3.64 million things, out of which 1.83 million are classified in a consistent Ontology, including 416,000 persons, 526,000 places, 106,000 music albums, 60,000 films, 17,500 video games, 169,000 organisations, 183,000 species and 5,400 diseases.

My concern for the potential for abuse in this project is much greater than that of wikipedia. How is wikimedia going to ensure that there are no malicious edits to this data? Any changes will almost certainly need stringent peer review.

Edit: As an afterthought, it would make a lot of sense to manage it like a git repository, where someone could submit a pull request for data changes, and then some subgroup or a trusted percentage of the population approves the request and it gets merged into the master dataset.

Given that the data is structured, to some extent it should be possible to automatically check its consistency.
