Structure or InteractionLinked Data as a Data Model … provides single structure to implement, query … acceptable if complete and accurate
Linked Data as an API … provides data to integrate, use … acceptable if understandable and usable

Need to focus on our goals … not on religious wars around ontologies
Need to find the balance between accuracy and usability
Need to recognize this is HARD and we’re not going to get it right the first time. Or the second.
Need to keep on keeping on :)
