W3C Invites Public Comment on Content Transformation Guidelines 1.0

W3C announced that the Mobile Web Best Practices Working Group has
published the First Public Working Draft for "Content Transformation
Guidelines 1.0." This document provides guidance to managers of content
transformation proxies and to content providers for how to coordinate
when delivering Web content. Content transformation techniques diverge
widely on the web, with many non-standard HTTP implications, and no
well-understood means either of identifying the presence of such
transforming proxies, nor of controlling their actions. From the point
of view of this document, Content Transformation is the manipulation in
various ways, by proxies, of requests made to and content delivered by
an origin server with a view to making it more suitable for mobile
presentation. The W3C MWI BPWG neither approves nor disapproves of
Content Transformation, but recognizes that is being deployed widely
across mobile data access networks. The deployments are widely divergent
to each other, with many non-standard HTTP implications, and no
well-understood means either of identifying the presence of such
transforming proxies, nor of controlling their actions. This document
establishes a framework to allow that to happen.
