Freebase schema design
Under paid contract with Metaweb Technologies, I designed graph database type and property models for Freebase, the open structured knowledge base. Google acquired Metaweb in 2010. Google used Freebase to seed its Knowledge Graph. The contract work modeled the motorcycle domain. On my own initiative, I tested the platform and built types and properties for bird species-habitat and trait relationships, then presented at scientific conferences on what that structure made possible for ecological data.
Why it matters: Machines reason over typed relationships, not prose. Freebase taught me to build the structure first and let the applications come to it.
