It seems the following email did not get delivered by our mailing-list. So posted again. BR, Tobias -------- Original Message -------- Subject: Re: [ltans] I-D ACTION:draft-ietf-ltans-xmlers-06.txt Date: Mon, 07 Jun 2010 19:06:38 +0100 From: Tobias Gondrom <tobias.gondrom@gondrom.org> To: ltans@ietf.org Dear Aljosa, thanks a lot for the great update version 06! I sent a few more purely editorial comments to you directly and have identified the following questions we should resolve on the mailing-list as other might have them as well: 1. Some more general questions about consistency of used terminology: - There is some inconsistency in the spelling (start with capital or small letter) of Evidence record? Shall we use "Evidence Record" or "evidence record" - same applies for Archive Time-Stamp/Archive Time Stamp/Archive Timestamp - same for in-sentence use of "type" and "Type" I have no preference, just think we should use consistent terms throughout the draft. In case you like, in RFC4998 when referring to a data structure we started with the capital letter and otherwise we used timestamp / evidence reocrd using the small letters. Maybe not the best solution either. As I said I have no personal preference for this. Questions: 2. section 3.1.1. paragraph 2: old: concatenated and a new hash value is generated from that string (there is exception when the first list is having one hash value, then this value is added to the next list). new: concatenated and a new hash value is generated from that string. There is an exception when the first list has only one hash value, in which case this value is the root hash value). comment: at least that's how I would understand it, otherwise it seems to trigger an endless recursive circle. The current wording seemed incorrect, but maybe I misunderstood s.th here? 3. section 3.2. item #2 Question: where is "canonicalization method C" defined or referenced??? 4. section 3.3. item#4: "If an archive object is having more data objects and the hash tree is omitted, also exit with result." Question: I am not sure why we have to exit in this case with (you probably mean negative) result??? Do we? And if yes, why? 5. section 4.2.1 Question about "the complete content of the last ATS MUST be time-stamped" Why is that? I thought only the old time-stamp has to be protected/renewed with a new timestamp? So we would not need to do this to the whole ATS structure.(btw. see also RFC4998, section 5 does it only on the timestamp) Or do I misunderstand s.th.? Thanks a lot, Tobias Ps.: unfortunately the IETF mailing-lists were down last week, so I hope this email will now eventually be delivered.
