Hi Simon, it's very much in line with the notion of responsibility in Yolanda's email yesterday. We are talking about the agent who is responsible for creating/deciding a new revision. But here, because it's a convenience relation, we don't make the process explicit. So, the agent responsible for the new revision doesn't have to be the asserter at all.

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 >> >> >> >> > > > -- 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
