A Major Release of PROV

The W3C Provenance Working Group is happy to announce a new release of the PROV Family of Documents, which provides a framework for interchanging provenance on the Web. This family includes 4 Candidate Recommendations that define the core of PROV along with several supporting documents some of which are first public working drafts. The PROV-Overview is the first entry point for PROV and provides a description of each document and how they fit together.

We are really excited about this release as it provides a comprehensive view of how Web developers and users can express and interchange provenance information. PROV is the product of the great interaction between the working group and both the developer and user communities. That interaction has made the specs better. The group is now looking for your continued interaction on two fronts:

1. Usage & Implementation

We are looking for your feedback about the usage and implementation of PROV. We are interested in all types of usage but in particular:

- Usage in datasets: Are you using PROV in your documents, web pages or dataset? - Extension: Have you extended PROV with your own vocabulary, ontology or data model? - Implementation: Does your application, web service, framework generate and/or consume PROV data?

If your using PROV, it would be great if you could fill out one of our questionnaires. You can find them at our Call for Implementations page. These are straightforward and shouldn't take two much time.

In addition, we are looking for those of you who are interested in implementing a validator or other system based on PROV-Constraints to both run through and jointly develop test cases with us. See the test case process for more details.

2. Comments on FPWDs and updated drafts

In addition to our Candidate Recommendations, we have released the following FPWDs and we are looking for your comments on those.

- PROV-Overview - PROV-XML defines an XML schema for the provenance model. - PROV-LINKS Defines extensions to PROV to enable linking provenance information across containers for provenance - PROV-DC defines a mapping between Dublin Core and PROV.

In addition, the PROV-Primer has been updated.

Please provide your comments to public-prov-comments@w3.org

Conclusion

We are excited to hear your comments and get your implementation experience. We already have many exciting implementations but be sure to add yours to the list.
