Re: "Microsoft Access" for RDF?

"If you don't like double housekeeping (most programmers know the pitfalls here), then using OWL or inference rules  you can also infer attendance from the arrival events."

Are "most programmers" who work for the Human Resources Department ignorant or just really scary ?
It's Friday.  Get thee to beer.  Quickly.

 Sorry, now I
 forgot my strawman! Too late on a Friday..
 
 So say the user of an triple-order-preserving
 UI says:
 <document> prov:wasAttributedTo :alice,
 :charlie, :bob.
 .. And consider the order important because Bob
 didn't contribute as much to the document as Alice and
 Charlie.
 In that case the above statements is not
 detailed enough and some new property or resource is needed
 to represent this distinction in RDF.
 Here I would think OWL fear combined with
 desire to reuse existing vocabularies mean that you
 don't get specific enough. Its OK to state the same
 relation with two different properties, and even better to
 make a new sub property that explains the combination.
 In the strawman, using more specific properties
 like pav:authoredBy and prov:wasInfluencedBy would clarify
 the distinction much more than an ordered list with an
 unspecified order criteria.
 
 In other cases the property is really giving a
 shortcut, say;
 <meeting> :attendedBy :john, :alice,
 :charlie .
 ..And the user is also encoding arrival time at
 the meeting by the list order. 
 But this is using :attendesBy to describe both
 who were there, and when they arrived. In this case, the
 event of arriving could better be modelled separately with a
 partial ordering.
 If you don't like double housekeeping (most
 programmers know the pitfalls here), then using OWL or
 inference rules  you can also infer attendance from the
 arrival events.
