Kristoffer, will you work on/with Hydra? If you have any questions, don't hesitate to ask... it puts more pressure on your supervisors to answer your mails if you do so on a public list :-P >> Yeah, it's easy for you to do because you know all of this.

The point is merely that you want to be able to make statements about > rtsp://camhost1.orienteering.org/stream and so it has to be in the subject > of some RDF, and then a subject or (S)CBD is overly restrictive. Assume I know nothing about your service at all. If you just send me the URL rtsp://camhost1.orienteering.org/stream via email or Skype, how would I be able to find the rest of your system? If I were to receive this URL, I would go to look up the protocol scheme [1]. The registry tells me I should have a look at RFC2326 [2]. Now I know how to start the stream, pause it etc. But there's nothing in RDF2326 which tells me anything else about your system. In other words, I wouldn't be able to find the data at all. Or do I miss something? >> Would you be interested to try to add another protocol? If so, which one? > > RTSP seems like a good choice... Cool! I'm looking forward to see what you are coming up with. Keep us posted. [1] http://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml [2] http://tools.ietf.org/html/rfc2326 -- Markus Lanthaler @markuslanthaler
