[snip] In a similar vein (temporal reasoning) you might be interested to check out this use case I sent to the RDF Calendar mailing list on Wednesday. Interesting thread followed with ical and rdf markup examples and http://lists.w3.org/Archives/Public/www-rdf-calendar/2003Mar/0014.html [[ I would like to use RDF calendar 'recurring events' to represent opening hours of shops and other services. In particular I'm interested in using the Semantic Web to support local small businesses, by mixing descriptions of their opening hours with other useful information: homepage of shop, opening hours, contact info, photograph of premises, lat/lang/alt location information, some indication of product lines and individual items for sale. ]] ... [[ The bit I'm currently interested in is this: It says, 'Currently [OPEN]', based on info about opening hours. Their summary for the 'Urban Gourmet' place around the corner from here: [[ Monday Closed Tuesday 4:00pm - 11:00pm Wednesday 11:30am - 11:00pm Thursday 11:30am - 11:00pm Friday 11:30am - 11:00pm Saturday 11:30am - 11:00pm Sunday 11:30am - 11:00pm ]] ]] followups: http://lists.w3.org/Archives/Public/www-rdf-calendar/2003Mar/0015.html (ical representation) http://lists.w3.org/Archives/Public/www-rdf-calendar/2003Mar/0016.html (rdf/xml representation, ical-in-rdf) http://lists.w3.org/Archives/Public/www-rdf-calendar/2003Mar/0021.html (running code from DanC, using N3 and Cwm) [[ Anyway... this is a long way from rules that specify ical exhaustively, but they do cover the "is the shop open now?" question pretty well, as long as you ask during summer time ;-) ]] DanC's RDF representation: http://www.w3.org/2002/12/cal/test/bus-hrs.rdf ...and timezone rules in N3: http://www.w3.org/2002/12/cal/tzrules.n3 This isn't quite the same scenario as your's, Roger, but it might well share some common structure, vocabulary etc... Also, thanks for prompting more discussion of compelling use cases, scenarios, inferences... these are very useful both in explaining the semantic web initiative and in motiviating and scoping further standards-track work. cheers, Dan
