delicious uses + to combine multiple tags. Eg. all links tagged with 'microformats' and 'accessibility': http://del.icio.us/tag/accessibility+microformats
So spaces could be encoded as +, but + could not be automatically parsed as a space in a single tag name.

(I think that "can" ought to be an RFC2119 "SHOULD", BTW; other specs may similarly need to have RFC2119 applied more rigorously). However, I see sites, in the wild, using dashes (hyphens) and others which encode spaces as underscores (e.g. del.icio.us; Wikipedia and other MediaWiki sites). See previously-compiled evidence, at: <http://microformats.org/wiki/rel-tag-spaces> Indeed, pages on the microformats wiki use hyphens in URLs which would seem suitable for use as tag spaces: <a rel="tag" href="http://microformats.org/wiki/existing-rel-values" > existing rel values </a> Operator, for example, regards: West+Midland+Bird+Club West-Midland-Bird-Club and: West_Midland_Bird_Club as three distinct tags, and does not discard them as duplicates (see test page at <http://www.westmidlandbirdclub.com/tag-test.htm> ). What do other parsers and implementations do? Should the spec be altered, so that the above, and: West%20Midland%20Bird%20Club are all deemed equal? Likewise, for that matter: West+Midland-Bird_Club This might be achieved by saying that spaces in tags SHOULD be encoded as encoded as either + or %20, but that parsers MUST treat dashes and underscores as spaces. Or we could simply say that spaces in tags SHOULD be encoded as encoded as +, %20, - or _ -- Andy Mabbett _______________________________________________ microformats-discuss mailing list microformats-discuss@microformats.org http://microformats.org/mailman/listinfo/microformats-discuss -------------------------------------------------------------------- mail2web.com What can On Demand Business Solutions do for you? http://link.mail2web.com/Business/SharePoint _______________________________________________ microformats-discuss mailing list microformats-discuss@microformats.org http://microformats.org/mailman/listinfo/microformats-discuss
