This is the home page for the Provenance space.
These pages are outdated.
Users are recommended to install and use the updated Taverna-PROV plugin which produces PROV-O traces and includes the data values. The Taverna-PROV traces are more complete, more are "correct" and addresses many of the known issues in OPM/Janus.
This presentation about Taverna's provenance support shows the architecture and outputs.
