i think this important thread belongs on the brand new
opendatakit-developers mailing list so i'm forwarding it there. as a
heads up for the sahana crew, we are also moving the repo to
http://code.google.com/p/opendatakit.
we don't have hard release dates set for aggregate-local, but i expect
it will be in a few months.
have you considered exposing an xforms api in sahana? doing so would
enable a number of j2me xforms clients...

What do you mean by a 'plugin'?
We already have a Controller which automatically generates XForms from
the Models.
This only provides a basic 1st-level which needs manually tweaking for
advanced functionality, but can easily incorporate a GWT-based editor
to do this.

the openrosa community has an emerging standard for downloading xforms
and posting xform instance data back to servers. what i mean by a
plugin is something on the sahana server that implements that
standard.

The time line for Aggregate 1.0 (which will include local datastores) is
first dependent on when the new standards are set that Yaw is referring to.
We are trying to minimize non backward compatible changes so we are grouping
a whole bunch in one big move to 1.0. Once the standards are settled it
will then take a few weeks of coding to implement things.
Aggregate is setup to automatically push data on reception of uploads to
another service. What type of api does your server normally take? We have
not setup aggregate to be fault tolerant in the push though so something
might get lost.
Cheers,
Waylon
