Hi Folks, enclosed are the concerns that were raised during today's roundtable. While they were raised while discussing Tom's proposal, they are viable input for the alternative version that is to be developed. Matthias ----------8<--- - Too complex: a) Providers were concerned that identifying and sending the 'right' response code may create additional cost. E.g., knowing whether you are a 1st or 3rd party may occur extra cost even if what you are doing is permissible in both cases (e.g., no tracking). b) Backend services may even be unable to discern the different cases - URL to text: A reason not to have an URL that was raised was that the text at this URL may contradict the compliance doc and may thus lead to confusion and/or legal inclarity - If a response depends on the request, then this may require extra effort since responses can no longer be statically defined - Cacheability": A point raised was that cacheable objects do not need a header since they cannot be used for tracking anyway. Counterpoint here was that if a site is, e.g., 100% cacheable and does not track, a user may still want to know that the site knows and respects DNT. - The current encodings may lead to misunderstanding - If the responses do not correspond to request codes, then this may lead to lead to legal uncertainty. E.g., if a user says "do not track me" and a site says "exemption #3", it is unclear whether this constitutes agreement or disagreement (Rigo) - If the responses are very specific, law enforcement gets easier. E.g., I do not use cookies is easier to verify than "I comply with DNT": The former can be tested while the later may require to investigate all exceptions. - response headers need to be able to signal out-of-band/prior consent that is an alternative to the the opt-back-in consent colleciton mechanism (if the site is confident that it satisfies the legal requirements).
