Reject then reinvent..?
Probably the most significant differences between the Userland 0.9x fork and rss-dev's RSS 1.0 were that the former eschewed XML namespaces and RDF support. I think it was around 2001 the <enclosure> element was added to the Userland branch, allowing it to point to media files. This brought back one of the capabilities that went with RDF, where a resource is a resource, and you don't really need a new element when the mime type changes. Then when RSS 2.0 came along, it included namespace support - no namespace of its own, but namespaced elements could now be added. Yesterday Microsoft announced an extension  for RSS 2.0 that gives support for the list data structure, something else that RSS/RDF has been capable of for 5 years. Looks like a pattern's emerging... I was wondering if there were any other cases around where a spec avoided using something like RDF on religious grounds, then later crept back in exactly that direction. (Or if anyone knows whatever happened to WinFS...) Cheers, Danny.  http://msdn.microsoft.com/longhorn/understanding/rss/simplefeedextensions/ -- http://dannyayers.com
