Open Provenance Model Wiki

The Open Provenance Model OPM was originally crafted in a meeting held in Salt Lake City in August 2007. OPM v1.00 was released to the community in December 2007. The first OPM workshop in June 2008 involved some twenty participants discussing issues related this specification, and led to a revised specification, referred to as OPM v1.01.

From the outset, the original authors’ intent has been to define a data model that is open from an inter-operability viewpoint but also with respect to the community of its contributors, reviewers and users. The early public release of v1.00, the first OPM workshop and the revised specification v1.01 are testimony of the community focus that is intended for OPM. This Wiki is set up to manage the collaborative effort for subsequent revisions of OPM.

Governance of the Open Provenance Model

A lightweight, structured process, inspired by the open source community, is adopted to manage changes to the OPM specification. The process, aimed at making decisions by consensus. is outlined in governance.pdf.

Latest specifications

The latest specifications are available from LatestSpecifications.

Work in Progress

Our current effort is to produce v1.1, whose aim, is to help us complete the Third Provenance Challenge. All activities related to v1.1 can be found at the page WorkInProgressV1pt1.

Proposed timetable for v1.1:

• Change Proposals (begins June 15, 2009, completes July 31, 2009)
• Proposals Review (begins August 1, 2009, completes September 6, 2009)
• Vote (begins September 7, completes September 14, 2009)
• Revised schemas (published September 30, 2009)
• Revised specification draft (November 15, 2009)
• Specification draft review (completes Dec 10, 2009)
• V1.1 specification (Dec 20, 2009)

Community Contributions

Profiles, i.e. specializations of OPM, with specific focus or for specific application domains are encouraged. Authors should feel free to submit such profiles by posting them on the CommunityContributions pages. To gain community endorsement, such profiles should go through the same revision process as the main OPM specification.

News

• June 10-11: A successful Provenance Challenge 3 Workshop involved some 25-30 participants (ThirdProvenanceChallenge), where it was decided to adopt a community process to produce a revision v1.1 to achieve the necessary inter-operability for completing the challenge.
