(Hoping that everyone on these lists now has time (after conferences and meetings in Amsterdam) to comment on Ron's writeup...) I have another question that I hope will spur discussion. In discussing with Sergey and Stefan the fact that a single arc specification may create multiple arcs (when the same arc label value appears on multiple resources), I was warned: "I'd recommend to be very careful with such things. RDF spec has a similar construct "aboutEach" which has been the subject of controversy and misunderstanding. The spec demands that the "batch" process of assigning the given relationship with every member of the bag (or in your case, every element with the same label) takes place during parsing, i.e. is transparent to the applications. However, a similar syntactic element "aboutEachPrefix" can only be expressed at the model level, i.e. using special relationships with predefined meaning." Having read through Ron's writeup, I don't think this really comes into play, since each *actual arc specified* (not merely each arc-type element) spins off its own set of RDF statements. However, I would be grateful for feedback on whether this is a gray area/problem in XLink and its relationship to RDF.
