h1. Freebase

Freebase is a crowdsourced knowledge base with very flexible schema and simple structuring. Bought by Google.
- I now read several presentations and howto's.
- I'm sure we can take away a lot of useful editing examples.
- E.g. look at this powerful query editor and language (MQL):
[http://www.freebase.com/queryeditor/about]
- I think that we definitely must include FreeBase and relatives in our RS4 explorations.

h2. Freebase data
We have experience with Freebase data (though not with the application):
- Our [http://www.FactForge.net] (FF) incorporates FreeBase data
- FB doesn’t use RDF constructs (e.g. rdf:type) nor RDFS/OWL inference
- We're partners with Google in the RENDER project
- As part of this, we're converting FB's constructs to standard RDFS/OWL constructs. FF includes a mapping layer (through Proton) that assigns standard rdf:type to FB data
- We used FB food data for mapping recipe ingredients to the USDA Standard Reference database in the [Edamam project|http://www.ontotext.com/case/pagane-foodKB]


h1. Parallax

[http://www.freebase.com/labs/parallax/]

- Note: I tried making a 2D chart of 3700 skyscrapers (Height vs Construction Cost) but it locked the browser.
- Wanted to try on fewer (highest 100), but when I added "More filters> Height", the Settings link didn't do anything.
