RE: Proposal for including EXI in XMPP

Dear Youenn,

Thank you for your response.

We also think EXI is exceptionally interesting and want to use it for other technologies as well. For instance, we are also looking at EXI compression in REST web services, especially for use with mobile devices hoping to improve latency by decreasing packet sizes.

Regarding using the preexisting EXI option header, I was also thinking the same thing in the beginning, but changed my mind thinking there are options that are not readily applicable in the XMPP case (for instance the Document/Fragment option), as well as options that are necessary in the EXI/XMPP case that are not applicable and available in the more general EXI case, such as the sessionWideBuffers option, added in revision 0.0.2. (I've attached the latest revision, with a note regarding this option §3.2).

Thank you for your time, and looking forward to your comments,
Sincerely,
Peter Waher

Hi,

That is an interesting piece of work.
My first thought when going through it is that EXI option negotiation may be a feature that is useful to more than XMPP.
That is very good that you bring it to the table.

Reading the spec quickly, I wonder whether the already-defined EXI header option element could be used for that purpose, especially in the case it can be serialized as EXI.

Anyway, I think the EXI WG will review this and get back to you.
Regards,
                Youenn

Hello

We have made a first draft of a proposal for incorporating EXI into XMPP networks. (See attached files.)

Anybody with an interest in EXI & XMPP are welcome to join us in this effort, please contact us. Any comments, suggestions, etc., on the contents of these documents are warmly welcomed and appreciated.

Sincerely,
Peter Waher
