Towards an accessible device independent Web


XHTML syntax is a foundational technology for content interoperability on the Web. Creating variable and multipurpose Web content for various devices and/or varying user abilities is still very difficult. Semantic markup makes a document more amenable to interpretation by software; it represents metadata associated with the content. Such metadata typically consists of a set of attributes or properties, and can be expressed as an XML or RDF vocabulary.

A markup document consists primarily of elements, attributes and text. Authors are increasingly familiar with using tags with extra attributes to extend their functions or refine the content of a given document. Attribute values convey information (metadata) to facilitate further processing of XHTML documents.

The method of using tags with extra attributes has succeeded in practice to cope with particular problem domains. We usually use implicit guidelines to capture the meaning behind these tags with special attribute values. Problems and limitations arise because of the absence of a common way to describe transparent semantics behind tags. This causes interoperability problems for content authoring, selection, adaptation, delivery and presentation.

Content metadata is a way to express the meaning of Web content and to map between vocabularies of the XHTML family of markup languages, their attributes and texts, and the underlying conceptual model that they represent.

These conceptual meanings may include:

Content metadata is information behind tags to express these semantics to help Web content presentation.

What we need is sharable, transparent and machine understandable explicit semantics that cover these concepts to achieve device independent presentation. Content metadata promises the ability to go beyond sharing simple tagged content to sharing some of the concepts behind the tags in the content and better device independent Web access.


The goal of the workshop is to discuss issues such as:

The outcome of the workshop will help W3C's Device Independence WG to create a content metadata specification. Some time will be dedicated to describing a core set of content metadata, which will be the starting point of the Working Group's specification efforts.

Expected Audience

We expect topic specialists who can make robust contributions related to suggested topics. We also welcome developers interested in both device independence and associated authoring/adaptation techniques.


The workshop program will be published on the Web for public dissemination. This will include position statements and associated materials.

In addition to this, a report on the discussions during the workshop will be made public after the meeting.

An attempt will be made to establish a core of content metadata. A summary of the results of this effort will also be made public.

All deliverables will be in Web format. There will be no printed proceedings.


Although the Workshop is public, it is restricted to 50 places. Each organization can provide at most two attendees.

To participate in this workshop, each person or organization must do the follow steps in the indicated order:

  1. Submit a position paper to the program committee, and optionally indicate intention to give a presentation
  2. If the position paper is accepted, complete the registration form detailed in the acceptance message
  3. If presenting, send the presentation material to the program committee

Details of these steps are given below.

Participation Step 1: Position Papers

Position papers are required in order to participate in this workshop (except for W3C team members). Each organization or individual wishing to participate must submit a position paper explaining their interest in the workshop no later than 13 September 2004. Position Papers must be sent via email to member-dimca-ws-submissions@w3.org. Submissions must be in valid (X)HTML, PDF or plain text. Images accompanying the text should, where possible, be in PNG format.

Participation Step 2: Registration

To attend, you must register by filling out the registration form. The details of the registration form will be sent to you by email after your position paper is accepted.

Participation Step 3: Presentations

Attendees are invited to submit presentations relating to the goals of the workshop. Presenters should allow half an hour for delivery, and be prepared to answer questions afterwards. Presentation material must be delivered by 25 September 2004. The registration form will include details on submitting presentations to the workshop. You should indicate your intention to make a presentation when you submit your position paper.


All position papers and presentations will be available from the workshop Web site. The workshop Web site will be public, so position papers and slides must be suitable for public dissemination. Speaker slides will also be available at the Web site after the workshop.

There will be no printed proceedings of the workshop and there is no participation fee.

Suggested Topics

Topics of interest for presentations include, but are not limited to the following:

The topics introduced by presentations will be the basis for debate and breakout sessions during the workshop.
