Re: CSVs and provenance

I think that an HTTP user agent handles the request and delivery, but not necessarily the creation of the CSV.
If I got it correctly, we can identify at least two activities (prov:Activity):

- delivery: the activity of delivery of the CSV, that is attributed to an agent (the http user agent by default?). Can affect the rendering, etc.
- generation: the activity of generation of the CSV. Determines the value contained in the file, etc.

The two may share one or more element (e.g. the agent controlling them), but this is not mandatory.
Did I miss anything?

Probably (a simplified version of) PROV is a good candidate to represent such relations? If I'm not wrong, there was some related discussion floating around in the chat two telcos ago (about "sum" cells?).
