[ghns] Re : about SoC proposal at Blender Foundation on GHNS + questions

Mon Apr 7 09:47:51 PDT 2008

Hi

 thanks very much for your detailed reply,
I'll adapt my Blender FOundation proposal with your input
and then maybe a KDE proposal later tonight.

I've looked at this diagram :
http://svn.kstuff.org/browser/trunk/kstuff/ghns/architecture-future.png
I would like to have one more info as to DXS.
I've noted that DXS is http only which seems ok for me.
looking at
http://svn.kstuff.org/browser/trunk/kstuff/ghns/architecture-future.pngmakes
understanding the desktop
software / server software break
down<http://ghns.freedesktop.org/software.php>(with 3 packages)
clearer.

do you know if
http://svn.kstuff.org/browser/trunk/kstuff/ghns/architecture-future.png is
implemented yet ?
is the communication language between client and DXS frontend still SOAP and
is REST going to replace that, or will both coexist ?
Is REST implementation just an idea, or a real intent ?

do you know if any of the current implementations of ghns clients listed on
http://ghns.freedesktop.org/software.php (first section) now talk to the DXS
frontend directly ? Or do they all still have the  current
architecture<http://svn.kstuff.org/browser/trunk/kstuff/ghns/architecture-current.png>(that's
to say clients talk to web app to browse through, and to another
specific server fetch and upload contents) ?

I did not take the time to have an in depth look at client local database...
Do you know if some software client app has implemented something (xml or
sql dbs) to list reading from the client hard drive what's been downloaded
where and the version info of those contents ?

your answers would help me a great deal for the proposal I'll post for the
Blender Foundation tonight.

Sincerely,
Jonathan
