Subject: RE: [tm-pubsubj] [Fwd: NISO-Sponsored INFO URI Scheme Published]
Patrick Thanks for the pointer. I was aware of the info URI scheme initiative but had not followed the recent developments. What strikes me at first reading is that info URIs are by design not dereferenceable: http://www2.elsevier.co.uk/~tony/info/info.html#usp "The unique aspect of info URIs is that info URIs are not dereferenceable. The sole purpose of info is the disclosure of the identity of an information asset from a public namespace." One could say at first sight that this makes info URIs non-conformant with PSI Requirement 2 "A Published Subject Identifier must resolve to an human-interpretable Published Subject Indicator." But maybe we should consider carefully before striking them out for this simple reason. The choice of "non-dereferenceability" (what a word!) is quite argumented at http://www2.elsevier.co.uk/~tony/info/info.html#non_deref and I think we should read that carefully. Although info URIs are not resolvable through the network, their very scheme provides completely non-ambiguous definition not only of the subject, but of publishing authority through a registration mechanism. So by design they are indeed subject identifiers, and intended to be. BTW http://www2.elsevier.co.uk/~tony/info/info.html#topic_map indicates topic map subject identity as a use case, although it describes the URI used as a "public subject indicator", which is not completely accurate terminology, should be "published subject identifier", but using it that way seems to me completely conformant to the spirit of non-ambiguous subject identification, is not to the letter of Deliverable 1. I think it interprets somehow the requirement of "resolvability" into something like: "A Published Subject Identifier must provide a non-ambiguous mechanism giving access to a unique human-interpretable Published Subject Indicator. This mechanism is usually network resolution, but it could be any other non-ambiguous process defined by the Publishing Authority." Note that "Subject Indicator" is defined in Deliverable 1 like an information resource, but not explicitly a network-retrievable one. So under those relaxed requirements, info URIs would be conformant PSIs. What do folks think ?
