Hello all http://microformats.org/wiki/haudio-issues#2008 D4 Andy Mabbbett said: "The required use of rel-enclosure does not allow for links to streaming files, which are not cacheable, and are thus outside the scope of rel-enclosure." http://microformats.org/discuss/mail/microformats-discuss/2008-January/011344.html rel="enclosure" is reused from Atom: "enclosure: a related resource which is potentially large in size and might require special handling, for example an audio or video recording" http://atomenabled.org/developers/syndication/#link It doesn't say anything about the caching the file (although in a later conversation I suggested as such) just that it may be "large" and it requires "special handling" Seems Appropriate! Close this Issue? or Discuss? Thanks Martin McEvoy
