Provenance, PROV-XML, and storage

Hello,

I'm experimenting with using the PROV-* standards to provide provenance of
data my system operates upon.  I'm very excited by the possibilities
offered by the PROV model, thank you for your work on this.

I admit my question may not be as interesting since it is more an
implementation question but I'm hoping someone here has some experience on
this.  Right now, I just want to store my provenance events in PROV-XML on
disk.  It is unclear to me the best approach to storing my provenance data.

Some of my questions are around the following:

* Should I store all provenance for my entire system in one massive
prov-xml file?  Seems wrong to me.

* Maybe I should store one set of provenance in a single file and impose an
ordering on the documents somehow (timestamps, timestamps in the prov data,
etc)?

Any pointers are appreciated.  Maybe it is just personal
preference/requirements driven in the end.
