- The needs of our company/organization in the field of
position-related information
NEC has many divisions which work in the field of position related
information. Those divisions cover wide thechnical areas such as GIS,
mobile contents, tracking of mobile phones, tracking of cars, ITS,
etc. As a manufacturer of equipements and software as well as an
Internet service provider, we believe we need the standard format of
position-related information as well as position information
itself, so that we could provide different carriers and users with
contents and devices based on the same standard.
We were/are a member of the MOSTEC, the team developing the POIX
specification, which was submitted to W3C as a Note and, now in Japan,
is being used as a basis of higher AP level specifications like G-XML.
We strongly believe this kind of specification should be a global
standard, not a Japanese local standard, since position-related
information should be transmitted to anoexchangeable anywhere in the world.
- Our general expectations on the final outputs of the workshop
Our general expectation is to establish a Working Group whose charter
includes standardizing
- the description of the position information; POIX has an element
<pos>, containing the information on the position and its
accuracy.
- the description of the time information, which is often refered
to togerther with the position information, especially when
handling it in a wide area,
- a protocol to transmit the position-related information; MOSTEC
is also develping this kind of protocol,
- a protocol to notify device's capability of measuring position,
- a framework for combining multiple datum about position
information using namespace,
- the usage of URLs, notifying the position information.
The POIX specification can be a baseline of the above standarzation.
- Our potential contributions to the discussion, related ideas, and
suggested solutions.
As a member of the MOSTEC, we developed and validated the POIX
specification. Through this experience, we can contribute by providing
the information about the implementation and operation of POIX-based
systems.
We can also contribute to the further disscussion about the
possibilities of the usage of position-related information, as we have
already developed some practical applications such as an information
system of local buses.
