[Standards] data element and cid: URL scheme

[Peter Saint-Andre]

In the XMPP Council meeting today, Dave Cridland said [0] he thinks that we can't use the cid: URL scheme [1] along with the proposed data element protocol [2].

I think Dave may be reading too much into RFC 2111, which states:

   The use of [MIME] within email to convey Web pages and their
   associated images requires a URL scheme to permit the HTML to refer
   to the images or other data included in the message.  The Content-ID
   Uniform Resource Locator, "cid:", serves that purpose.

That provides a (one?) rationale for the cid: scheme, but as far as I can see it doesn't say that the cid: URL scheme is restricted for use only in MIME-encoded email messages and MUST NOT be used in other contexts. Specifically, the usage we're proposing with the data element is conceptually similar to the email usage and therefore at least seems to not violate RFC 2111. But maybe I say this only because I really don't want to define a new URI scheme if I don't have to... ;-) [0] http://logs.jabber.org/[EMAIL PROTECTED]/2008-01-09.html#14:04:11
