Re: [m2m-iwg] Re : OMA-DM? (Werner Keil)

Werner,
The Eclipse M2M group has no relationship with the JCP. I don't think anyone on this list would know why the JSR is dormant.

Subject: [m2m-iwg] Re : OMA-DM? (Werner Keil)
Nicolas,
Thanks for the information. That is pretty much what the experts from Cinterion said, adding, that some proposed "OMA-Lite" improvement may help improve its usefulness, but it seems, there has not been a lot of progress to any of these changes.
They may not know every Cinterion flyer or slide marketing creates, but the only page where I saw "OMA-DM compliant" more or less means, that customers or partners (e.g. those using their boards inside devices, I mentioned one in my talk by a Spanish vendor) could use it, but it is very carrier-centric, and in a world of iTunes or Google Play, the carriers have far less control over devices especially on phones which the protocol was intended for. So some carriers who use Cinterion modules (e.g. in N America) may use them together with an infrastructure using OMA-DM, but Cinterion itself does not actively use or support it at the moment.
That didn't mean nobody else does, they were only speaking for themselves, beside talking about the pros and cons, too.
If especially in the US it's so widely spread, it does seem strange, that nobody was willing to pick up the dormant OMA-DM JSR at JCP. Well I'd interpret it as a signal of insecurity by vendors about the Phone market, but should play a role big enough for Java in the M2M market again (and at least Cinterion and others build a JVM into more and more of these modules) then it would be weird not to support it.
WebSockets and other standards defined by other organizations were immediately picked up, so why not this one?;-)
Kind Regards,
Werner
