    Description of Working Group:

    As more and more resources become available on the Internet, some
    applications need to acquire geographic location information about
    certain resources or entities. These applications include navigation,
    emergency services, management of equipment in the field, and other
    location-based services.

    But while the formatting and transfer of such information is in some
    sense a straightforward process, the implications of doing it,
    especially in regards to privacy and security, are anything but.

    The primary task of this working group will be to assess the the
    authorization, integrity and privacy requirements that must be met in
    order to transfer such information, or authorize the release or
    representation of such information through an agent.

    In addition, the working group will select an already standardized
    format to recommend for use in representing location per se.  A key
    task will be to enhance this format and protocol approaches using the
    enhanced format, to ensure that the security and privacy methods are
    available to diverse location-aware applications.  Approaches to be
    considered will include (among others) data formats incorporating
    fields directing the privacy handling of the location information and
    possible methods of specifying variable precision of location.

    Also to be considered will be:  authorization of requestors and
    responders; authorization of proxies (for instance, the ability to
    authorize a carrier to reveal what timezone one is in, but not what
    city.  An approach to the taxonomy of requestors, as well as to the
    resolution or precision of information given them, will be part of this
    deliverable.

    The combination of these elements should provide a service capable of
    transferring geographic location information in a private and secure
    fashion (including the option of denying transfer).

    For reasons of both future interoperability and assurance of the
    security and privacy goals, it is a goal of the working group to
    deliver a specification that has broad applicablity and will become
    mandatory to implement for IETF protocols that are location-aware.


    Two further deliverables of the WG will be:

    o An example API for application-level access to/management
      of link-based location information.  That is, for instance, the WG
      may describe an API for secure, privacy-enabling user/ application
      handling of location information specific to a 3G wireless link
      technology.

    o Development of i-ds that make security and privacy integral to
      location information in HTTP and HTML, based on the work in
      draft-daviel-html-geo-tag-05.txt and
      draft-daviel-http-geo-header-03.txt.

    Out of Scope:

    This WG won't develop location-determining technology.  It will work
    from existing technologies and where the technology is undeveloped,
    will state that applicability may await others' developments.

    This WG won't develop technology to support any particular regulatory
    requirement [e.g. E.911] but will provide a framework that might be
    used for private/secure definition of such technologies by other
    bodies.

    Coordination:

    The WG will coordinate with other WGs developing general privacy and
    location-aware functions, e.g. the SIP WG, so that the WG deliverables
    can be used by them.  Other coordination should include the NymIP
    research community, WC3, and the Location Information Forum.
