When saying 'what time on the tape' are you referring to the physical position on that tape ? I suppose the same concepts and mechanisms can be used as when referencing content on a tape or in a Broadcast stream, Particularly, when the tape uses the broadcast format as "file system" (e.g., MPEG TS). It is up to the tape device design how to arrange (fast) access across a tape. Possibly, the tape is arranged with additional information to assist the driver. Anyhow, that seems to me outside the scope of the URI. To keep this focus I think it helps if we talk in terms of storage devices. > I propose to use XML to handle the hooks neccessary. I am not sure I understand what you suggest here. What hooks ? And how would you use XML ? I assume you mean to use XML for specifying the application language. That also seems outside our current scope of discussing URIs. > Time Code could be used as is and another *Time* Code should be developed: > topology relevant time for download. I do not understand this phrase: What 'Time code' are you referring to? For what and how could it be used 'as is' ? What is the other ' *Time* Code ' What do you mean by 'topology relevant time' ? What topology are you referring to ? (position on tape ?) Before answering all this, can you think of what the consequences are for URIs: are we missing a requirement ? Warner.
