W3C W3C Member Submission

Tiling and Layering Module for SVG 1.2 Tiny Submission

Submitted Materials

We, W3C Member KDDI CORPORATION, hereby submit to the Consortium the following specification, comprising the following document(s) attached hereto:

  1. Tiling and Layering Module for SVG 1.2 Tiny

which collectively are referred to as "the Submission". We request the Submission be known as the SVGTL Submission.


This specification defines the features and syntax for a Tiling and Layering Module for SVG 1.2 Tiny. This specification focuses on Web Mapping based on hyper-documents.

Intellectual Property Statements


KDDI CORPORATION hereby grants to the W3C a perpetual, nonexclusive, royalty-free, world-wide right and license under any KDDI CORPORATION copyrights on this contribution, to copy, publish and distribute the contribution under the W3C document licenses.
Additionally, should the Submission be used as a contribution towards a W3C Activity, KDDI CORPORATION grants a right and license of the same scope to any derivative works prepared by the W3C and based on, or incorporating all or part of, the contribution. KDDI CORPORATION further agrees that any derivative works of this contribution prepared by the W3C shall be solely owned by the W3C.


REQUIRED for W3C Members
The organization I represent on the W3C Advisory Committee agrees to offer licenses according to the W3C Royalty-Free licensing requirements described in section 5 of the 5 February 2004 W3C Patent Policy for any portion of the Submission that is subsequently incorporated in a W3C Recommendation.

Required proprietary technology

No, this is an open-platform specification based on non-proprietary technology. Furthermore, this architecture respects the philosophy of Linked Open Data advocated by Mr. Tim Berners-Lee.

Suggested action

We suggest that the Consortium establish a Mapping Task Force and a W3C Recommendation based on this specification, within the SVG WG.

SVGTL may have some relationship with existing W3C groups. KDDI does not have an opinion about the details of cooperation with these activities.

SVGTL is related to the Linked Data-related projects of the W3C, as it may be considered to be a new application of Linked Data.

In addition, it may be related to the Government Linked Data WG, since maps are such an important source of information for government; this explains the interest shown by the Japanese Government in making SVGTL a de-jure standard.

Of course, it will be related with POI WG where one of the main application is Mapping.


To help with this work, we provide the following expectations and information to the Consortium.

The most important application of SVG in Japan is considered to be maps. And, the JIS de-jure standardization of this (SVGTL) specification is being promoted through the JIS standardization of SVG 1.2 Tiny. Initial JIS standardization completion is scheduled for 2012. This activity has the basic stance of cooperation with the standardization activity of W3C. By the way, Mr. Doug Schepers and KEIO staff have known of this circumstance for some time (see [SVG IG], [SVG IG JP]).

In addition, we are preparing the publication of an implementation of SVGTL as an open-source project based on WebKit. These activities may increase the possibility of a social contribution to SVG and this (SVGTL) specification.
