Mark, I tried looking up the owner of nbc.com (using various web-based whois service), but I could not find details. The website www.nbc.com points at the NBC TV channel/broadcast. I suspect that GE owns NBC? In our view the tv:URI should identify a TV broadcast. Looking at the TV broadcast known in the USA as NBC (via the website http://www.nbc.com), then we can see that it has four different schedules: E (Eastern), C (Central), M (Mountain), and P (Pacific). These four TV broadcasts can be seen as four different ones, so we may need the following tv:URIs: * eastern.nbc.com * central.nbc.com * mountain.nbc.com * pacific.nbc.com On the other hand according to the website of the company 'owning' NBC, NBC Universal, there are 10 TV stations transmitting NBC: WNBC (NBC4 New York), KNBC (NBC4 Los Angeles), WMAQ (NBC5 Chicago), etc. So we may also need the following tv:URIs: * wnbc.nbc.com * knbc.nbc.com * wmaq.nbc.com etc. The tv:URI registry that we need here will contain the list of available tv:URIs, i.e. eastern.nbc.com, wnbc.nbc.com, etc. and to each tv:URI in the list information is associated identifying the TV broadcast. For instance: tv:eastern.nbc.com => "The eastern schedule of the NBC TV broadcast in the USA, website reference http://www.nbc.com" tv:wnbc.nbc.com => "The TV broadcast transmitted by the TV station WNBC (NBC4 New York) of NBC Universal, website reference http://www.nbcuni.com/About_NBC_Universal/Company_Overview/overview02.sh tml" Regarding the involvement of the company NBC or the company GE in the tv:URIs mentioned above: * if they get involved in specifying the information associated to the tv:URIs mentioned, they are very welcome. * if they do not want to get involved in specifying the information associated to the tv:URIs mentioned, fine as well. They do not have to get involved, but they are sure welcome. The main relation with the DNS domain name nbc.com is by 'human' association. Someone wanting to have information about tv:eastern.nbc.com, might have a look at a website http://www.nbc.com as mentioned in the tv:URI registry. Looking up the domain nbc.com (via whois) would perhaps be less successful for explaining what tv:eastern.nbc.com points at. So actually there is in our view no hard relationship between tv:URIs and domain names. About the resolvability of tv:URIs we have a future hope that they might become resolvable by automatic means. But in the mean time we are quite happy at getting the list of available tv:URIs and some identifying information. At configuration of a TV application, the tv:URI can then be configured by human intervention after a lookup in the tv:URI registry. Note that a similar situation already exists in Europe in case of the use of Showview (see http://www.showview.com): each buyer of a video/hard disk recorder with Showview needs to configure the mapping of Showview channels onto actual TV channels. Making the resovability dependent on the DNS system is not our intention as this would *force* each tv:URI resolving to be dependent on the cooperation of the domain name owner of the (super)domain in the tv:URI.

So would there be any relationship between, say, "tv:nbc.com" and General Electric (the current owner, per the DNS)? If yes, do you intend to reuse the association already maintained by the DNS/ICANN, or do you intend to create a new registry to make this association? If not, don't you think General Electric might express concern about not owning the set of tv URIs using the nbc.com name? You also mentioned that anybody would be able to register a tv URI. Again, don't you think GE (or Disney or ...) would balk at that? > Note that this implies - as already stated in > RFC2838 - that it is not the intention that tv:URI's are resolved > through the DNS. It sounds like you're leaving the door open to resolvable URIs which is good, but what would you recommend for those that want them? And a meta question; would this discussion not be more appropriate for the URI list (uri@w3.org)? Cheers, Mark.
