> Ah right. I was meaning something more like this so that you can skip the quoting business entirely and have the visual hierarchy match the conceptual hierarchy: Well, if it's supposed to be compatible with all the HTML crap out there, and even most MUAs' broken encoding of plain text email, it might be hard, but in principle, I'd think this should actually be rather simple: Simply specify an algorithm that defines how to segment a text/plain body into paragraphs and how to thus generate MIME object-scope IDs per paragraph (by simply numbering them) and use that same structure to provide UI elements per paragraph. Then, if the user writes a per-paragraph reply, generate a multipart/alternative body, with one text/plain part in traditional quoting style, optionally with format=flowed, and one alternative application/fancy-paragraph-foo part which contains in some sort of serialization format references to the message+paragraph IDs, that paragraph's text, and the corresponding reply text. This way, a receiving MUA that doesn't support application/fancy-paragraph-foo will display an ordinary quoted plaintext body, and also, if a communication partner uses different MUAs, you can still reply to an email sent using an MUA without application/fancy-paragraph-foo support and still have the feature work if the reply is then read in an MUA that does understand it. Also, including the text of the original paragraph makes sure you can still display a message sensibly when the displaying MUA doesn't have the mail it's in reply to - you'd just have to be careful to not misrepresent the authorship information as reliable. > What if user A deletes the entire conversation they were having with user B, and user B replies to the deleted conversation [...] * g * (is there any way to escape asterisks to their literal meaning?!) Well, the rationale I've heard is that it's easier to make sure new participants in a conversation can read up on what has happened so far ... which obviously would be solved far better by attaching a thread of message/rfc822 attachments when adding a new participant that the recipient could navigate using their MUA's usual UI instead of having to read a close to unreadable unstructured mess of emails. |
