If you're building something cool with the TagMaps web services, please let us know or just swing on by the mailing list and shoot the wind with other TagMaps developers/users. Do it all in the tagmaps discussion group.
The base URL for world explorer data API is:
http://tagmaps.research.yahooapis.com/services/rest/taglookup.php?
The collectionSearch request follows standard HTTP GET syntax. See constructing REST queries for details.
