This page provides supplemental material for our IPAW 2012 paper, "Resolving Incongruent Granularity in Open Provenance Environments". If you'd like to know something that isn't here, feel free to contact http://tw.rpi.edu/instances/TimLebo

Tools mentioned in Section 3

• retrievals: pcurl.sh and pcurl.py
• preparations: justify.sh
• conversions: csv2rdf4lod asserts provenance during conversion. It knows where the inputs and outputs will be stored on the web and describes them.
• publishings: pvload.sh uses pcurl.sh to retrieve an RDF file at a URL, loads it into the given named graph, and inserts provenance about the URL retrieval and graph load into the same named graph. files are placed into htdocs to suit the locations asserted by the converter. Discussed at Named graphs that know where they came from.

Service mentioned in Section 5

• named-graph-derivation.rpy implements the SADI service that provides the PROV-O abstraction of the granular PML captured by csv2rdf4lod.
• https://github.com/alangrafu/lodspeakr/wiki was used to create views of the main provenance for each stage of conversion.
