Re: The Provenance Spectrum....

Hi Joanne and Scott,
In the Provenance incubator we agreed on the following definition:
Provenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource. Provenance provides a critical foundation for assessing authenticity, enabling trust, and allowing reproducibility. Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance. 



A couple of key points in the above definition that will hopefully help to "draw the line in the definition" - metadata, record past events (the use of temporal dimension is critical to definition of provenance and has consensus in the current provenance WG also [1]), foundation for trust and reproducibility (these are often confused to be synonymous with provenance but are actually derived from or are use of provenance), and contextual or in other words each domain/application defines its own set of provenance terms.


Hope this helps.


Best,

I was impressed.
