Proposed Group: Overlay Community Group

The Overlay Community Group has been proposed by Lionel Wolberger:

Lately a set of web based accessibility remediation services has been made available to web content providers under the term: Overlay. These function by adding a snipet of javascript into a web content provider’s page. Typically, this single line of additional code functions to enable, on each page load, additional content processing, delivered through the overlay provider’s servers, before the content is delivered to the end user. While this routing paradigm is by no means unique to accessibility applications, it does introduce accessibility opportunities and tradeoffs. In this community group we seek to clarify overlay technologies when applied for accessibility purposes, informed by sober analysis of what technological innovation at the edge can offer.

You are invited to support the creation of this group. Once the group has a total of five supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account.

Once launched, the group will no longer be listed as “proposed”; it will be in the list of current groups.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on

Thank you,
W3C Community Development Team
