Part 1 -- Organisational differences
JIL -- Joint Innovation Lab
It's unclear exactly when JIL begun, though this commercial joint venture under Dutch law was founded by:
Can JIL scale to include other operators or members in respective territories? It's unclear.
Notice there are no Web browser vendors involved in the venture.
After looking at JIL, it seems they have adopted most elements of the W3C widget P&C specification and extended it in some (minor) ways. However JIL has not contributed any specification material back to W3C discussion.
Collectively they aim to launch a software applications store to rival that of the Apple Itunes store.
BONDI from the Open Mobile Terminal Platform
Nick Allot on OMTP's BONDI W3C positioning says it best:
From the outset W3C has been the target SDO (Standards Organisation) for the BONDI specs. Considerable time and effort has been expended by both the office and the members on this relationship. To date I think we can congratulate ourselves on two major successes. Firstly, we have successfully contributed to the Widget P&C spec ensuring all the core feature and requirements of BONDI have been adopted in the current specification. Secondly, through the Device API security Workshop which OMTP co-chaired and the efforts with the Web Applications group, the new Device APIs and Policy working group is now set up and scoped precisely to mirror the BONDI work.
To date, BONDI contributes to the Web standards track whilst JIL adopts (and fragments) W3C widgets.
