Welcome to the
G-XML Project website.
[English | Japanese]
On
this website you will find information detailing the G-XML Project. This
project is currently being carried out by the Database
Promotion Center, Japan [1]
a non-profit organization, which is under the auspices of the Japanese
government's Ministry
of Economy, Trade and Industry (METI).
Announcement
on JIPDEC/DPC Integration
[1]
From April 1, 2006 the DPC (Database Promotion Center) [Tokyo, Japan] http://www.dpc.jipdec.jp
and the G-XML Project have joined forces with JIPDEC (Japan Information
Processing Development Corporation) [Tokyo, Japan] http://www.jipdec.jp.
The new organization will be called JIPDEC/DPC. JIPDEC is the primary
organization in Japan for administering and certifying ISO compliance in
information privacy and security management. JIPDEC is also involved with
electronic commerce and electronic document interchange. The business areas
of both JIPDEC and DPC are well suited for each other and will provide a
strong base for future activities.

Current
Status of the G-XML Project, Summer 2006
The G-XML Project was sponsored by the Japanese government’s Ministry of
Economy Trade and Industry (METI) and carried out by the Database Promotion
Center (DPC) from fiscal 1999 (April) through 2004 (March). One of the
principal goals of the G-XML Project was the creation of an XML based protocol
for encoding spatial data, and to actively promote, both in
Japan
and internationally, the use of such a protocol. During
these five years, the G-XML Project has overseen the creation of G-XML, and
has undertaken a number of promotional activities.
As development work on G-XML continued
and the results of a number of test beds
were analyzed, it became clear that in addition to the creation of a spatial
protocol, the existence of “spatially enabled” contents data was
essential. With the majority of
work finished on the G-XML protocol and the international standards activities
well underway, the G-XML Project began to concentrate on the promotion of
other “geo-enabling” activities.
During the major term of project
activity, the G-XML protocol underwent three major revisions. G-XML versions 1
& 2 were Document Type Definition (DTD) based. Through significant
commitment, G-XML Version 2.0 was adopted as JIS X 7199 on
August 25, 2001
. During the work to update G-XML 2.0 to 3.0 G-XML Project
Team Members worked together with OGC’s GML team to converge major sections
of G-XML with GML. With the conclusion of work by OGC, GML was submitted to
ISO where additional work has been on-going. With the upcoming finalization on
ISO-GML (ISO 19136) one of the goals of the GML Project will be fulfilled.
Activity is already underway in
Japan
to incorporate ISO GML as a JIS accepted standard.

G-XML
3.1 Specification Released…
The
G-XML 3.1 English Specification document has been released. This document
consists of an overview to the new updates of G-XML 3.1 in addition to the
complete schema documentation. The English G-XML 3.1 Specification Document is
intended to give interested international developers insight into what G-XML
is and by using G-XML how they can more quickly develop interoperable spatial
web services, by using the pre-defined service constructs.

The G-XML 3.1 English Specification
document has been released. This document consists of an overview to the new
updates of G-XML 3.1 in addition to the complete schema documentation. This
past fiscal year (April 2003 - March 2004) the G-XML Project Team worked to
refine G-XML and add new features, while working closely with both the OGC GML
RWG and ISO GML RWG to insure that G-XML 3.1 was a well constructed
application schema of GML 3.1.

Project Overview and
Introduction:
Aims and Goals of the G-XML Project...
The aim of the G-XML Project is to
create a protocol for encoding spatial data through extensions built upon XML.
The goal is that G-XML will provide a method for freely accessing and using
geographic information over the Internet.
The G-XML Project has established a
consortium of individuals from government, academia and the private sector to
contribute to the design of the G-XML specification and the implementation of
prototype systems built upon G-XML.
Within the scope of this project, a
specification document has been created. Versions 1.0 and 2.0 of these
documents are freely available here in English or Japanese. Presently,
the current specification is Version 2.5. In early 2001 work began to converge
G-XML with the OpenGIS Consortium's
(OGC) GML
specification. This work was completed in the spring of 2002 and from May 2002
GML 3.0 (the G-XML converged version) has entered into the ISO/ TC211
family of specifications and will progress towards becoming an international
standard.
