The Network Friendly Webapps CG [2] is a place where we are trying to promote use cases / development for needed technologies and developer guidelines related to network efficiency (and in general, resource efficiency and better UX for networked/smartphone apps), and webapps in particular [1].

Whether that CG or CoreMob take further actions on this OMA liaison depends partly upon what W3C does with CoreMob: as we have suggested we would like it to focus on closing feature gaps, performance, and looking to the next set of essential features. Other considerations of "mobile" use cases e.g. usability and efficiency (key drivers of our earlier input in the MWI) can also be considered by CoreMob or the Network Friendly Webapps CG - I don't really care (except that it would be nice to have one CG working toward both goals, IMO).

W3C has a liaison relationship with OMA, which over time we've used to help promote synergy in standards for the Web and service enablers developed at OMA. In this case OMA is continuing its focus on network efficiency by defining service enabler specifications and related APIs allowing apps to request certain network-efficiency promoting features/services implemented in the device. We've had a lot of difficulty in W3C so far getting such features exposed to the Web apps through APIs (e.g. the long history of the DAP Network Information API, and earlier proposals for even more robust APIs coming from the submissions of OMTP and WAC). But that doesn't mean we will stop trying... it's our belief that eventually the rationales for support of resource efficiency will gain more supporters in W3C, and we will see some of these platform capabilities exposed through APIs defined in W3C, e.g. as has recently been discussed, maybe defined as abstracted delivery-service-oriented APIs (e.g. "retrieve this content when the next network connection is established for some other purpose or within the next 30 minutes whichever comes first").

I would think that the general topic of being interested in efficient - with use of the underlying network, with the user's battery and wallet, especially when roaming - would be an area of interest to Coremob. Though DAP would know better than me the capacity of this area to reduce adults to tears.

In terms of establishing a liaison with OMA, as things stand I wonder if a CG is able to do that? Would that change if Coremob was an IG?

Re Network Friendly CG - my understanding is that its focus was quite specific to a GSMA initiative, "Smarter Apps for Smart Phones" which was due for update at the end of 2012, though that may not be a correct perception.

Yes, I am not a member of that group, but perhaps someone who is could please forward the liaison information (my message and attachment?)

Dear CoreMob participants:

The Device APIs working group (DAP) received a liaison statement from OMA (see below and attachment) regarding Device Apps Network Efficiency [1].

We think that this could be a topic best discussed in coremob, so maybe it should be added to the list of  items to consider going forward.

I should note that Tobie shared some comments on the DAP public list suggesting a good approach might be to create APIs that make efficiency transparent to developers  [2].

What do you think of  further discussing this work in coremob, and coordinating with OMA on the topic?

regards, Frederick
