Still ok... "(special)" alluding to 'so-called' "information resource"? And parenthetically because of controversy over 1) objective charactterisation of such a 'special' kind of resources and 2) whether robust characterisation is actually necssary or possible? > And Ive been reading Xaioshu as meaning that that resource, whatever > it is, is what is "obtained from" the Web; in which case, his position > makes more sense (though I still don't agree with it :-) FWIW my reading of Xiaoshu's is that he complains that the TAG holds the position that it takes what is "obtained from" the web (aka. an awww:representation) as being *the* referenced resource, and that that is not a position that the TAG should hold - which is fortunate (maybe) because AFAIK it is not infact a position held by the TAG (or by TR/webarch). That the awww:representation obtained could be *a* resource is possible. However, the obtained representation is just not (usually, ever?) the resource being referred to in the original reference. I'm still thinking about your book example... particularly "This entity involved in the this transaction, here and now, is what you are asking about; it is the thing that the name you just used refers to". The physical book seems to serve as both message (awww:representation) and resource. The closest 'electronic' example I can get to is an immutable file/document that has a single invariant representation over its entire lifetime. FWIW: I think Xiaoshu, you, I and the TAG (at least the one I was part of) hold(held) very similar positions. > Pat > > ------------------------------------------------------------ > IHMC (850)434 8903 or > (650)494 3973 > 40 South Alcaniz St. (850)202 4416 office > Pensacola (850)202 4440 fax > FL 32502 (850)291 0667 mobile > phayesAT-SIGNihmc.us http://www.ihmc.us/users/phayes Stuart --
