The W3C Provenance Incubator Group is announcing its first report: “Requirements for Provenance on the Web”. The report describes the group’s consensus on the requirements to support provenance in a variety of web contexts, applications, and use. The report is based on the following documents produced by the group:

• A proposed set of provenance dimensions to organize major issues for provenance on the web
• More than 30 use cases developed by the group that cover all those dimensions illustrating a broad range of usage of provenance
• More than 250 user and technical requirements for provenance motivated by those use cases

The report will serve as a basis to organize a state-of-the-art survey on provenance. The group welcomes comments and feedback on this report from the Web community. More information about the W3C Provenance Group, including its current activities and future plans, is publicly available on its wiki site.
