Blueprint for the J2ME client
J2ME is the most widespread environment for mobile devices:
There should be a simple set of forms for data entry.
GPS coordinates should be taken automatically if available (inc via Bluetooth) or can be entered manually, where not available automatically.
The back-end transport is best done via SMS as this is cheap & widely-available.
- compressed multi-part SMS to get maximal throughput.
The forms should be updatable via SMS.
This would work like the one which comes with FrontlineSMS, but be Open, as well as Free:
JavaRosa is a fast-developing framework which uses XForms & J2MEPolish:
- Web based xforms generator -> http://code.google.com/p/purcforms/
This supports using Mesh4j to do synchronisation via SMS:
XForms editor we could use to clean-up our autogenerated XForms (written in GWT, so includable as a simple HTML page. Not for non-techies though!):
KUIX can be used to develop lightweight applications which work across may handhelds & forms can be customised easily via XML/CSS:
Old, un-maintained J2ME client for the PHP back-end, which just uses XML-RPC (=> requires Internet):
For the J2ME side:
For the Python side:
