[Swift-devel] Open Provenance Model log exporter

[Ben Clifford]

Part of Provenance Challenge 3 (PC3) is to export data into the open 
provenance model (OPM).

I've committed a crude exporter for that into provenancedb/ in the SVN in 
r2633

I've also added details in the provenance.xml docbook page in that 
directory about how open provenance model vocabulary relates to Swift 
concepts.

My experience so far has been that OPM is quite in sympathy with the 
thoughts that I've had so far about Swift provenance. I'll be interested 
to see (in PC3) if any meaningful interop between implementations can be 
achieved.

At present, my thoughts tend towards us being able to export Swift data 
into some other provenance system, rather than importing other peoples 
data from not-Swift into our database.
