Not if you literally mean an event in EPG terms. This implies a solution limited to existing EPG event data only, which I do not agree with. >The open question is whether that requirement may _only_ be met >by putting time-related information in the URI itself. It is not that simple. Specifying time (or not) in a scheme is not the only design criteria. >You agree that there are valid schemes that meet the requirement >without such encoding. Syntactically "valid", yes. The best design - not necessarily. >That indicates that the encoding is not itself >part of the requirement. (The fact that one can devise schemes that use >the encoding is not relevant to the question.) There are always multiple solutions to a problem. I am not advocating multiple concurrent schemes to do the same thing, nor am I in any way advocating that eliminating time encoding is the utmost design goal in meeting the URI requirements. There may be other reasons for needing a time-based approach that outweigh a general desire to avoid it. In the end, we must consider all reasonable solutions, of which there will be compromises, including possibly desires to eliminate time in the URI(s).
