Hello Dale - I tried to submit as this as an ID, however, the site is saying the ID Tool won't be available until 4/3. I made a lot of changes to the document based on the feedback. I removed the references to the GUID (probably not needed) and hopefully clarified more within the doc and references. Thank you again for your feedback. Please see the attached draft for review. Hopefully, this draft is a lot cleaner. Jarrett Wold | Ad-ID LLC Director of Technology & Platforms 646-708-8131 jwold@ad-id.org -----Original Message----- From: Dale R. Worley [mailto:worley@alum.mit.edu] Sent: Monday, March 14, 2016 10:44 PM To: Jarrett Wold <jwold@ad-id.org> Cc: urn-nid@apps.ietf.org Subject: Comments on draft-adid-urn-00 Here are a bunch of comments on draft-adid-urn-00. Overall the concept seems fine, but the document needs cleaning up. The title contains "Adverting". Have you run the draft through a spelling checker? The following is an example of an Ad-ID Identifier in its canonical representation: ABCD0001000 The canonical URN representation of the same Ad-ID Identifier is: urn:adid:ABCD0001000 urn:adid:ABCD0001000H The 32-bit unique representation of the Ad-ID is: urn:adid:cuid:36faeaba This example is difficult to follow. The first item is straightforward, as it is an 11 character string. But the next item isn't clear: by definition, a "canonical" representation is one representation chosen from among many. You can say that both urn:adid:ABCD0001000 urn:adid:ABCD0001000H are URN representations of the Ad-ID identifier, but only one of them can be canonical. Also, it would be helpful if you explained why both URNs correspond to ABCD0001000, or at least provide a reference to some description which will explain it. But, reading http://www.ad-id.org/how-it-works/ad-id-structure, it seems that ABCD0001000H is not the *same* Ad-ID as ABCD0001000, but rather the Ad-ID for the corresponding High Definition version of the asset. You need to clarify this so that the example is not misleading. It is not clear how the further "32-bit unique representation" corresponds to the preceding three representations. It's reasonably clear what "32-bit" means as the URN contains a sequence of 8 hex digits, but it's completely unclear what is "unique" about it. Remember, this is the introduction, which should be readable by people who don't already understand the technology, including people who don't already understand Ad-IDs in all their forms. There's some general trouble about the indentation of text. For instance, it seems that "The identifier structure is as follows:" should be 4 spaces to the left, "Non alphanumeric ("special") characters and spaces are not valid within an Ad-ID." should have a blank like above it and be moved 3 spaces to the left, and "A Canonical Full Ad-ID ..." should be moved 1 space to the left. This text has some redundancy that should be removed: A Canonical Full Ad-ID Identifier shall conform to the syntax specified below using ABNF (as specified in IETF RFC 5234): The URN representation URN-ADID of an Ad-ID Identifier conforms to the syntax (expressed using ABNF (as specified in [RFC5234]): The production adid_prefix = (ALPHA / %x30-39) 4*alphanum ; first character not zero is incorrect on two counts: As written, the first character can be zero (which ix %x30). The strings generated are 5 characters. What you want is adid_prefix = (ALPHA / %x31-39) 3*alphanum ; first character not zero The instances of ALPHA and DIGIT might be intended to be "alpha" and "digit". Or do you mean to reference the productions ALPHA and DIGIT in RFC 5234? If so, you should eliminate the productions for "alpha" and "digit" in the draft. The BNF does not show how the "urn:adid:cuid" URNs are generated. As the BNF now stands, those examples are invalid. Ad-ID URNs are resolved via URN resolvers run under Ad-ID's responsibility. It would be helpful here to provide a pointer to the documentation for the resolvers. The validity of an URN-ADID can be checked using Ad-ID's web services. Ditto. Dale
