RE: FW: Potential Location Summit

LIF (Location Interoperability Forum) specifies carrier interfaces
related to location, including position data, privacy, roaming. We just
released LIF TS 101 v3.0.0, which has its primary contribution
harmonization with OGC GIS specifications, and some new features related
to roaming. See www.locationforum.org.

WAP Forum (Wireless Application Protocol) specifies presentation
interfaces, but in fact they have also released a similar specification
(that doesn't deal with roaming--because "presentation" doesn't
technically have to deal with roaming, and I'm not sure about privacy).
WAP Forum and LIF are working to harmonize their work and arrive at a
single standard. In fact, they both come from the same starting point,
so this isn't very hard.

OGC (Open GIS Consortium) specifies interfaces relating to geographic
information systems, including mapping, routing, point-of-interest
search, geocoding, reverse geocoding. LIF and OGC work pretty closely
together. Don't ask me why this works where other relationships
haven't, I'm not sure I've figured out the sociology of standardization
groups yet. LIF and OGC standards are very compatible.

3GPP specifies interfaces relating to the WCDMA version of 3G wireless
communications. In fact, 3GPP's relationship with LIF has been one
where 3GPP articulates requirements for location, privacy and roaming,
and LIF specifies them.

3GPP2 specifies interfaces relating to the CDMA2000 version of 3G
wireless communications. LIF's relationship with 3GPP2 is not as strong
as 3GPP, probably because not enough CDMA carriers are involved in LIF.
(I think this is a little like SOAP and .Net. WCDMA is less proprietary
so requires more cooperation, CDMA2000 is more proprietary, so requires
less cooperation [or overhead, depending on your point of view].)

OMA is a new organization that is trying to unify standards for network
operators. It is working closely with lots of standardization groups.

With respect to guidance for IETF, I think you can look at these efforts
(other than OGC) as relevant when network operators (also called
"wireless carriers", Sprint, ATT Wireless, etc.) own the portal. They
become less relevant if operators don't control location information.
Most of us believe that operators will control [=charge for, required to
enable, etc.] location information for at least the next 5 years or so.

Hope this is helpful. There is a lot going on in other groups, and
privacy is a big concern for them as well. So working together seems to
be a good idea.

As Bechet pointed out by referring to the charter, what geopriv (or
any other WG) does is quite transparent. Regardless of whether
anyone who also participates in geopriv attends this "summit", Mr
Brynes should be encouraged to participate in geopriv, and post
information regarding this meeting to the geopriv mailing list. It
would be useful to the IETF to know what these other organizations
are attempting to accomplish.
