Ontologies Vs. Formats Vs. Schema Vs. APIs

Ontologies Vs. Formats Vs. Schema Vs. APIs: Tom Gruber thinks that "ontologies are a technology to make a minimal commitment while being as clear as possible. The minimalism comes by abstracting away from implementation details, which are biased by needs of efficiency and convenience. The clarity comes from careful specification, with at least some of the specification document couched in a formal language that forces one to be explicit about assumptions and the meanings of terms."
