What should be our standard of proof for determining whether a standards document that claims to be technically identical to another standards document actually is identical? This question has some relevance to the work of the IETF, because some standards bodies produce joint standards which become available under different terms: one standards body will charge money for their copies of a joint standard, while another standards body will make their copies of the same standard available free of charge. For example, a number of character-set related standards for which ISO/IEC charges money are available for free from ECMA. In the case of IEEE 1003.1, the Open Group states that the Base Specifications of the Single UNIX Specification Version 3, ISO/IEC 9945:2003, and IEEE 1003.1 are the same document: http://www.unix.org/version3/iso_std.html I see no compelling reason to dispute this statement made by one of the copyright holders. I might be able to locate a PDF copy of IEEE 1003.1 to verify this claim. (I doubt I would want to obtain the physical bulk of a dead-tree version of the document.) Is it wrong to note in a document's References section that a set of standards are technically identical? It will obviously increase the size of references if an author does this. If you also believe that we should require authors to distinguish between the dead-tree version of a standard and the online copy of the standard, References sections could get really unwieldy. ---Tom _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
