- 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.
