This is where the public schematic and layout symbol libraries will eventually live when the database is finally built. There are plenty of parts and symbol files out there but the problem with them is quality and consistency as well as a the more artistic attribute best described as style. Style is not something that can be easily solved since how you want to partition a particular schematic symbol is often really just a personal decision of what works best for you.
The contents of the publicly available database will use a known-working approach to the quality, consistency and accuracy issues. Quality will be handled by peer review where all registered users can "rate" a particular entry as well as comment on it. Consistency and to a reasonable degree, accuracy, will be handled by automated inspection and testing.
As you can hopefully see, two goals get served by this approach; (1) You don't waste your time on garbage files, and (2) I find out quickly what needs to be fixed or removed.
Being that this is a competitive world and not everyone will be willing to release their work, the database system will also be released so you (your company) can maintain your own private database.
