RDF / Semantic Web Software

Other Software

Contributions

• Redland (contributor), an RDF toolkit in C. I wrote the Turtle serialiser (RDF syntax for those with taste) and the “trees” storage.
• Ardour (contributor), a DAW and sequencer. I wrote the (MIDI) sequencing support (initially as a Google SoC project).
• LV2 (co-author), an extensible audio plugin specification based on RDF.

Academic

• PEMS, a Parallel External Memory System (the implementation of my Master’s thesis)
