Design decisions
o Wikipedia / DBpedia as identity provider o Don’t trust the triples o Consistency not required o Triples are immutable o First map, then add o sameAs is different

Lessons learned
i o Data is noSi_y o Data is hard to understand o Labels are hard to get / unreliable o The Semantic Web is slow o No idea how to represent the diverse
knowledge o Semantics decided by ‘commoners’, not
experts
o Semantic Web researchers should build a Semantic Web application
