This document defines a language for road information referred to as RWML (Road Web Markup Language) and describes its usage. This document is a draft and it is published to request comments from interested parties in general. It is subject to changes and it is not recommended to make a fixed software that cannot be modified and to make other standards based on this specification.
This specification was originally proposed by Hokkaido Development Bureau, Civil Engineering Research Institute. The working group is a joint research institute and consists of representatives from a number of enterprises and organizations. The working group was organized to define Road Web Markup Language, RWML for describing road information by using XML. This specification is the result of the discussion in the working group since June 1998.
Each member in the working group submitted a proposal for the responsible part in this specification. Those proposals were assembled and have been discussed. But please note that all issues have not discussed thoroughly nor all items has yet agreed unanimously as of October 20, 1999.
After we created RWML 0.71 version on Oct. 20th 1999, RWML specification working group dissolved once, however, we reached the agreement to review it again at the public collaboration "study on utilizing technology of In-transit Advanced Information Communication Society Retail Distribution Information" started in February 2001. In this study, this RWML is reviewed practically through some experiments and added and modified where necessary.
The version of this specification is 0.80 as of October 29, 2001.
In this updated specification 0.80, necessary additions and modifications were made in order to use this study for Niseko-Yotei-e highway experiment. Parts not used for this experiment are not reviewed. We will review as needed in the future. Therefore there is a great possibility for this 0.80 specification itself to be altered significantly.
If any technology and any specification that may affect this specification come out as a result of other standardization work regarding road information description, we will consider making the adjustments in this specification. And we are also willing to suggest standardization of this specification as open technology.
This specification was created on the basis of RWML 0.71a centrally by experiments of an XML technological study working group public collaboration, "Study on Utilizing Technology of In-Transit Advanced Information Communication Society Retailing Information" . The experiement took place in the summer.

RWML was created as a language for describing road information on the Web and it adopts the XML technology. XML has recently drawn keen attention in electric commerce, digital broadcasting, and other fields.
XML (eXtensible Markup Language) is a meta-language which provides a generalized method to define a "data-set" so that it can be interpreted by machine(machine-readable). XML employs the method to describe the data from HTML which is a language for describing web pages and provides a generalized way to extend it. Data content is enclosed by
The emergence of XML technology enables any data to be distributed among web-site systems on the platform such as Internet/Intranet. XML has drawn attention in electric commerce and digital broadcasting field because XML is recognized as a basic technology of information distribution in a highly information-oriented and data communication-oriented society. RWML was created to distribute road information on such platform. RWML can make value-added information for users by combining road information with other information such as weather information (weather forecast etc.) and local events information.

Road-related information defined by RWML consists of road information, weather information, disaster prevention information, and regional information. Each information includes common basic information that describes data about administrators etc.
The factor name of the route factor will be "RWML".
The attribute version number is recorded as ("0.80 or 0.8")
<RWML version="0.80"> </RWML>
