Predicted TimeLine

• Deliverable 1 - Friday, 30th June

  Extend and finalise the initial draft of the protocol specification started by David Yip (/src/jabber_whiteboard/protocol/protocol.tex), intergrating as much of the standard protocol underdevelopment at http://wiki.jabber.org/index.php/Psi_Whiteboarding which must include the following

  • Specification for conflict resolution
  • Use Case for peer to peer and Multi User Chat session establishment
  • Use Case for communication of edits between sessions
  • Listing of valid message types
  • State transition diagram of Inkboard Clients

• Deliverable 2 - Friday, 14th July

  Develop and finalise the XML schema that is implemented by the inkboard clients, this will define the valid message types that may be transferred

• Deliverable 3 - Friday 28th July

  A basic inkboard client developed using the perdo XMPP client, must be stable enough to be integrated with the trunk, that contains at least the following

  • Initialisation and Destruction of multi user and peer to peer session
  • Basic communication of changes between documents

• Final Deliverable - Monday 21th August

  End of Summer of Code project, a fully stable inkboard intergrated into the inkscape trunk, ready for inclusion in the release of .45, features to include:

  • Conflict Resolution
  • Local Undo mechanism

Project Log

5/07/06

graduation next week is interfering with the progression of the project, but i have managed to develop a system for reducing the undo history stack, and have decided on session establishment protocol,. I just really need to sort out the service discovery which needs input from other, finalised the protocol document up until that point

2/07/06

Still cant decide on a protocol for MUC session establishment, I think this will need to be voted, it has quite large effects on implementation. there has been talk about limiting the undo queue needed which is rather a large implementation detail. I am late with the first deliverable, but I think it was expected with how late I was starting the project, It has also been slowed down trying to get multiple parties to agree, It will certainly be ready in time along with the XML schema

1/07/06

Discussed some of the last issues with the JEP, MUC session establishment, I think we need to have another conference. Issue include service discovery, the sandbox and actual transfer of in band images

30/06/06

I actually wont need to patch ejabberd, somone has sent the patch, hopefully it will be introduced into latest stable, darcs is being incredibly annoying to install

29/06/06

Joonas and I have agreed on most protocol issues and decided to work on the same JEP. Some of the tradeoffs, I have agreed that <new> elements should be sent as raw svg, which means I have to compile change events to new svg elements. The other major one being that we will not use the id attribute to track elements, instead a whiteboard specific id given during the creation of an object

28/06/06

the first draft of the protocol used a revised version of the old inkboard session negotiation protocol, I think CAP / disco are more suitable for the initial stages of session establishment, so I am researching this to hopefully commit to a revised protocol soon
I also followed up the issue of presence stanzas being incorrectly ordered on ejabberd servers, it look like I would have to submit my own patch to resolve this

27/06/06

Dicussed with joonas about the integration of the jabber.org and my protocol, so far there are only 2 issues, address of elements, which I need to discuss with david yip, and the sending of native svg through the protocol. which is hopefully easy to resolve

26/06/06

Started my draft of the whiteboard protocol, for now I will keep an updated copy at http://debrowse.com/protocol.html
Jabber.org hosted a discussion on whiteboarding issues, it went quite well, as both peer to peer and muc with client side synchronisation are looking to be supported, with an option for muc with a server component

25/06/06

Have had a few problems integrating a jabber_whiteboard board specific gui to the pedro client, im going to put any development work on hold until I can get the protocol drafted

24/06/06

Managed to fix the windows build, it ignored makefiles_insert and compiled old code, there are issues with compilation against older versions of gtk.

23/06/06

I spent today merging the INKBOARD_PEDRO branch with the trunk, all works well on linux, I have disabled inkboard to be built on windows for the time being as there is some rather confusing compile errors, which I will hopefully fix tomorrow

22/06/06

After discussion with David Yip and Joonas of the jabber.org SoC project, A proposal has been set for conflict resolution, I have started extending the protocol document that can be found in the pedro branch. We are setting up a time convenient for a whiteboard related conference in the next week or so

21/06/06

I have finished uni and can start working full time on the protocol / lib conversion. We have decided to integrate the whiteboard gui into the pedro gui. I am starting my work with adding the whiteboard gui into pedro, and defining groupchat and peer to peer initialisation protocol
