Open Provenance Architecture

Interesting:

Ultimately, our aim is to conceive a computer-based representation of provenance that allows us to perform useful analysis and reasoning to support our use cases. The provenance of a piece of data will be represented in a computer system by some suitable documentation of the process that led to the data. While our applications will specify the form that such a documentation should take, we can identify several of its general properties. Documentation can be complete or partial (for instance, when the computation has not terminated yet); it can be accurate or inaccurate; it can present conflicting or consensual views of the actors involved; it can be detailed or not.
