Legacy sites at openprovenance.org

I recently wrote a blog post about the relaunch of openprovenance.org. Today, I am pleased to announce the availability of two websites providing a historical perspective on the work that took place in the provenance community.

The Provenance Challenge website is hosted at https://openprovenance.org/provenance-challenge/WebHome.html. It is kept in its original wiki look-and-feel as it constituted a significant community effort that led to the PROV standardisation. At the time, the community decided that it needed to understand the different representations of provenance, their common aspects, and the reasons for their difference. The Provenance Challenge was born as a community activity aiming to understand and compare the various provenance solutions. Three consecutive provenance challenges took place. A significant artifact that resulted from the Provenance Challenge series is the Open Provenance Model.

The Open Provenance Model (OPM) website is hosted at https://openprovenance.org/opm/. OPM is the first community data model for provenance. OPM was designed as a conceptual data model for exchanging provenance information. It contained key concepts such as Artifact (called Entity in PROV), Process (called Activity in PROV), and Agent. It also introduced notions of usage, generation and derivation of artifacts.

Of course, all this is now superseded by PROV, the W3C set of Recommendations and Notes for provenance. These legacy sites are made available to the community for reference. We aim to persist those pages and URLs in the future. Feel free to link to them!
