On the weekend of [Bastille day][Bastille_Day] some of us gathered and worked around some
|
||
interesting new features in XMPP implementations. [Wisolv][Wisolv] generously
|
||
sponsored the venue and provided us with their office in Villeurbanne (next to
|
||
Lyon).
|
||
|
||
I think most of us are quite happy with this sprint, we managed to get quite
|
||
some work done. On the agenda were DOAP, Message Reactions, Occupant-id,
|
||
various fixes and discussions, also including work on a Jabber client for Haiku!

### DOAP - Description Of A Project
|
||
|
||
[There][list1] [are][list2] [many][list3] [different][list4] [lists][list5]
|
||
[of][list6] [XMPP software][list7], each listing the favourite features of the
|
||
author, being displayed in various ways, having specific highlights, being more
|
||
or less up to date and maintained, and generally not really usable by a
|
||
machine. The [DOAP project][DOAP_GH] provides a way for each project to host a
|
||
[semantic][Semantic_web] description of itself, which can then be used by
|
||
anyone to display information about XMPP software.
|
||
|
||
A few years ago, Link Mauve [submitted a proposal][DOAP_thread] to extend DOAP
|
||
with information most of these lists want to expose, but it didn’t get much
|
||
interest… until this sprint! PulkoMandy wrote a [table for
|
||
clients][Clients_table], edhelas wrote a [DOAP file for Movim][DOAP_Movim]
|
||
(which can be seen rendered using the former [here][DOAP_Rendered]), and Link
|
||
Mauve wrote [a schema][DOAP_Schema] and [a JavaScript integration][DOAP_JS]
|
||
into the XEP pages (an example can be seen here for [Bookmarks][DOAP_Example]).

### Reactions
|
||
|
||
Some time ago, [Movim][Movim] [implemented reactions][Movim_Reactions] using the [Message
|
||
Attaching specification][XEP_0367]. [Dino][Dino] developers felt that the situation could
|
||
be improved, especially some issues with non-supporting clients, and started
|
||
working on a new specification a few weeks ago. The protoXEP has been submitted
|
||
[to the inbox][XEP-Reactions] this weekend!
|
||
|
||
Edhelas [reworked the Movim implementation][Movim_Reactions_Commit] using this new specification,
|
||
mathieui worked on an implementation in poezio (not yet merged, but [the
|
||
Slixmpp bits are][Slix_Reactions]), and fiaxh and larma started an [implementation in
|
||
dino][Dino_Reactions].

||
### Occupant-id
|
||
|
||
[Occupand-id][XEP-Occupant-id] is a protoXEP that was also submitted by larma
|
||
this weekend.
|
||
|
||
It mandates that MUC components provide a stable and unique id that is
|
||
attributed per room per user (real JID). This can be used in semi-anonymous
|
||
rooms, where it is usually not possible to ensure messages are coming from the
|
||
same participant between rejoins.
|
||
|
||
Some clients are talking about requiring occupant-id for features like Last
|
||
Message Correction, or Reactions, in semi-anonymous rooms.
|
||
|
||
A [prosody module][Prosody-occupant-id] is now available and is usable with the
|
||
current release (0.11) or trunk.

||
### And more
|
||
|
||
PulkoMandy started porting [Jabber4Haiku][Jabber4Haiku] -- now renamed Renga
|
||
-- to gloox. Fiaxh worked on [stable and unique IDs][XEP_0359] in dino.
|
||
Slixmpp finally [uses non-predictable ids][Slix_predictable_ids]. Mathieui
|
||
and I worked around issues with asynchronous APIs in Poezio and Slixmpp.
|
||
xmpp-parsers got a new [release][xmpp-parsers-0.14], fixing
|
||
[documentation][xmpp-parsers-docs] on the way!
