MimePartSerializer

[Conal Tuohy <co...@paradise.net.nz>]

I'm working on a set of email components for Cocoon (mostly finished), and
there's one part I'd appreciate comments or advice on.

A MIME message can contain a number of parts of different types (including
binary attachments), and these have to be extracted from the message.
Currently I've written a MailSource which includes binary MIME parts, like
this:

<mail:message>
	...
	<mail:part type="multipart/related">
		...
		<mail:part type="image/jpeg"
			id="002101c22de7$6e1a2e20$0100007f@x7g1x4"
			file-name="hottype_chomsky911.jpg"
			size="18014" encoding="base64">

			(based64-encoded data here)

		</mail:part>
		...
	</mail:part>
</mail:message>

This is currently useless ;-) because you can't do anything with the base-64
encoded data, but I'm planning to write a MimePartSerializer that will
decode the binary data, and could even add "disposition" etc. headers to the
HTTP response. Does this seem like a reasonable idea?

The other option I considered was to produce only a reference in my
<mail:message> document, e.g.

<mail:part type="image/jpeg"
	id="002101c22de7$6e1a2e20$0100007f@x7g1x4"
	file-name="hottype_chomsky911.jpg"
	size="18014" encoding="base64"/>

(NB mail:part element is empty, but @id is a unique reference)

Then I could access the binary parts in a separate pipeline using a
MimePartSource that referred to a part within a message.

I think the first option is simpler, but maybe there's some other approach I
haven't considered? Any thoughts?

Cheers
