This BoF will focus on the goal of getting large amounts of external data into Drupal, and storing it and displaying it in such a way that new relationships between the data - new knowledge - can be discovered, or created.
The result of this process is the creation of a "custom knowledge bases" that is suited for a particular domain of knowledge.
There also are some other closely related questions that will be interesting to discuss, and which could be topics for BoFs in their own right:
Entities vs. Nodes in D7: how to best architect D7 sites. If you have very large amounts of data to store in a Drupal knowledge base, what should you store in Nodes and what should you store in Entities?
Views 3: querying external data with Views 3. Views 3 will be a major data mashup tool for external data, and for creating custom knowledgebases.
