Introduction to the Open Provenance Model<\/a> (OPM) from\u00a0Luc Moreau, University of Southampton.<\/p>\n

Came out of a series ‘provenance challenges’ – driven by a desire to understand provenance systems. First 3 provenance challenges (around interoperability of provenance information from different systems) led to the OPM, which became the basis of a further challenge event.<\/p>\n

OPM is ‘annotated causality\/dependency graph – directed, acyclic’ – it is an abstract modle with serialization formats to XML and RDF. It encourages specialisation for specific domains through profiles.<\/p>\n

A simple use case inspired by Jeni Tennison blogpost http:\/\/www.jenitennison.com\/blog\/node\/133<\/a> [worth reading to look at practical application of provenance in RDF]<\/p>\n

Lots of detail here that I didn’t get – need to go and read\u00a0http:\/\/openprovenance.org\/<\/a><\/p>\n

OPM itself doesn’t say anything about aggregations – but using OPM it is possible to build an ontology that expresses this – there is a draft proposed collection profile – but needs more work.<\/p>\n

Some work around being able to add a digital signature to provenance information – to validate it as from a specific source\/person.<\/p>\n

… at this point I’m afraid the 5am start got to me and I didn’t manage to capture the rest of this presentation \ud83d\ude41<\/p>\n
