Approval of last telecon minutes from 17 April

Any objections? No.

Resolution: publish minutes for April 17

Face to face planning

Rich asks for information about the results of the face to face questionnaire. Dave notes that he sent a summary to the member list a while back, and that there have been a number of email exchanges, culiminating in the narrowing down of the choices to 24-25 July in Pisa, Italy, and hosted by Fabio Paterno and ISTI. Our thanks to Fabio for kindly volunteering.

Pisa is an ancient city and famous for its leaning tower. Dave will liaise with Fabio to provide logistical details. The following face to face will be in Mandelieu, France as part of the Technical Plenary, and will be held in the week 20-25 October 2008.

Location

Dave gave a talk on location based services in the W3C track at WWW2008. GPS is only one of several approaches being deployed. AGPS (assisted GPS) offers reduced battery demands and is more robust, but involves access to servers. U-TDOA (uplink time difference of arrival) is increasingly common and doesn't involve any changes to devices. It is being deployed to meet regulations on access to device location for calls to emergency services (E911, E112).

GPS may not work well in high rise areas and within buildings. U-TDOA works better in these situations and has the advantage of working with all handsets, whereas the fraction of handsets with GPS is still small in many countries. There is also interest in higher accuracy positioning within buildings, although this is at a much earlier stage of development.

Kevin: location is being discussed in GSMA.

Kevin offers to post a pointer to materials describing how European operators are being required to open up access to device location. He adds that he plans to give more details on how the GSMA activities relates to UWA in the near future once the GSMA is ready for publication.

Dave notes the location API in Android and Google Gears is expected to be picked up by the proposed W3C Web Applications working group, that is currently under AC Review. There is a big challenge to avoid a fragmented approach to location based services given the wide range of existing solutions.

Dave has been invited to give a presentation at the OMTP meeting on May 22nd and will try to provide a short overview of W3C's work on mobile and device capabilities in particular, including location.

Device Coordination telecon

The idea was to organize a regular telecon for discussions relating to the device coordination work items at a time that is within regular office hourse for people in Asia, as the existing UWA telecon is unreasonably late for them.

Based upon the results of the questionnaire, it doesn't see as if we are quite ready to set up the device coordination telecon slot. However, that is likely to change in the near future as Kaz provides a submission on printing.

Personalization

Rich has posted some questions on personalization and expects to provide more details in the near future. He is keen to ensure that the work reflects commercial needs. One of the questions relates to which properties are exposed via server-side APIs.
