Hi Luc, Yes, the issue can be closed. Minor note - the constraint mentions "wasDerivedFrom(id, e2,e1)", but this ASN does not seem to be defined in the derivation section. I think it should be "wasDerivedFrom(id, e2, e1, attrs)". Or does it mean empty attribute set (so default prov:steps="n")? thanks, Simon On 30 November 2011 13:07, Luc Moreau <L.Moreau@ecs.soton.ac.uk> wrote: > Hi Simon, > We have made some changes on this section in the latest WD. > We are proposing to close, > Can you confirm it is fine? > Regards, > Luc > > On 11/11/2011 12:01 PM, Provenance Working Group Issue Tracker wrote: >> PROV-ISSUE-149 (revision-asserter): Why does revision record include an asserter?

This is no different from any other assertion: it is always in some asserter's perspective that the assertion is true. We don't include the asserter explicitly in Used, Generated, Derived or other records, so why do we for Revision? >> >> >> >> >> > > -- > Professor Luc Moreau > Electronics and Computer Science tel: +44 23 8059 4487 > University of Southampton fax: +44 23 8059 2865 > Southampton SO17 1BJ email: l.moreau@ecs.soton.ac.uk > United Kingdom http://www.ecs.soton.ac.uk/~lavm > > > -- Dr Simon Miles Lecturer, Department of Informatics Kings College London, WC2R 2LS, UK +44 (0)20 7848 1166 Provenance in Agent-mediated Healthcare Systems: http://eprints.dcs.kcl.ac.uk/1273/
