3. My Life as a Semantic Web Developer
• Constantly working with different data
sources, formats, vocabularies etc.
• Was frustrated by limited tooling around
conversion, query prototyping and editing
– Especially the *nix/Java bias of available tooling
• Seemed pointless to keep writing tiny
Java/.Net programs to do everyday tasks
