Re: Provenance, PROV-XML, and storage

Hi Mike,

Great that you're looking at PROV.

I think this is a personal preference how you store the files. But one way
to do it is based on around the file the provenance is for. So if you have
a file content.txt you would store the provenance of it as
content-prov.provx

Thanks
Paul
