I meant to add to that: the trick that's used with xml formats might be extended to rdf+xml-based formats. Assuming someone created a media type that was based on rdf+xml, it seems that the trick of parsing the mime type would be handy if it was something like blah/vcard+rdf+xml But then, I have a love-hate relationship with media types as currently concieved, so I could change my opinion on that. - Chris -----Original Message----- From: Chris Wilper Sent: Friday, September 19, 2003 10:36 AM To: bryan; xml-dev@l... Subject: RE: mime types and xml dialects HTTP 1.1 has content negotation: http://www.w3.org/Protocols/rfc2616/rfc2616-sec12.html#sec12 But you might be after something simpler. Ideally your xml-based formats would have their own media types, and the fact that they end in "+xml" (as they should) would signal to a client that they can be processed in either a specialized or generic way. - Chris -----Original Message----- From: bryan [mailto:bry@i...] Sent: Friday, September 19, 2003 6:32 AM To: xml-dev@l... Subject: mime types and xml dialects Hi, When returning a mime type of a resource, if that resource is a dialect of xml then the more general type is text/xml but the more specific type can be application/rdf+xml which in turn can be even more closely specified as a subset of RDF. Currently what I'm doing is returning text/xml for generic xml documents, and application/rdf+xml for all dialects of rdf; what I'm considering is the possibility of adding http headers that specify that there is a range of mime types possible for a resource, and their likelihood of being the best type for a resource. Anyone done anything with that, pointers to discussions, projects and similar stuff in the past would be helpful. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl> ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
