One way of modeling the provenance data

[DougBurke]

The discussion by William Waites at http://lists.okfn.org/pipermail/open-bibliography/2011-July/001064.html is interesting, namely

<http://bnb.data.bl.uk/doc/resource/014938424> opmv:wasGeneratedBy [
    a opmv:Process;
    opmv:used [ ## maybe give this its own URI, but don't block on that
        a bibliographic:MarcRecord;
        dct:modified "YYYY-MM-DDTHH:MM:SSZ" ## from 005
    ];
    opmv:wasPerformedAt [ 
        a time:Instant;
        time:inXSDDateTime "YYYY-MM-DDTHH:MM:SSZ"
    ].

although you really need to read the full email for context.
