Slide deck presenting the Provenance support of Taverna workflow system, detailing architecture, ontologies and how results are exported as Research Object bundles, including the PROV-O provenance of the workflow run. This upload is the PDF version, for PPTX source, see https://www.slideshare.net/soilandreyes/20130529-taverna-provenance-pptx-source/

3. ONTOLOGY STACK
tavernaprov
• Lists, errors, byte content, checksums
wfprov + wfdesc
• Workflow execution, parameters, processes
PROV-O
• Activity start/stop, generation of values

4. INTERMEDIATE RESULTS
• Within the Taverna Workbench, the provenance database is
used for showing intermediate results and previous runs
