W3C Technical Architecture Group Work Plan

12 January 2012

Note: this version integrates decisions made at the 4-6 January 2012 TAG F2F.

This page is used to track the current work of the TAG, and also to note projects that are completed or abandoned. Projects completed prior to mid-2011 are not tracked here, and this note is used only for major projects that represent and ongoing investment by the TAG. Other work of the TAG can be tracked by reading the archives of the www-tag@w3.org mailing list, or from the TAG's tracker page.

Top Priority

The TAG identifies several of its ongoing projects as being most significant and having top priority for successful completion. The following table provides a list.

Product	TAG Members Assigned	Upcoming Checkpoint(s)
Fragment Identifiers and Mime Types	Peter Linss, Henry Thompson, Yves Lafon	Earlier plans called for a TAG Finding to be prepared in 2011, but that did not happen. The product page linked at left was prepared by Henry Thompson as input for discussion at the 4-6 January 2012 TAG F2F. We agreed at the F2F to reinvest in this topic: the next step will be to refine the work plan proposed by Henry.
Publishing and Linking on the Web	Jeni Tennison, Dan Appelquist	June 2012: TAG W3C Proposed Recommendation
URI Documentation Discovery	Jonathan Rees, Henry Thompson	17 February 2012: The TAG will announce to the community a baseline proposal for amending the resolution to issue httpRange-14, and along with that a call for change proposals, inviting the community to suggest better alternatives. August 2012: PR(s) or similar document covering the following: URI documentation discovery architecture ontology (RDF vocabulary) as needed August 2012: TAG Note on semantics of metadata for 'information resources'
MIME architecture for the Web	Larry Masinter	The first round of work on this topic was done in 2011, and resulted in the publication of MIME and the Web: draft-masinter-mime-web-info-02 At the 4-6 January 2012 TAG F2F it was agreed that a new plan would be created for a second round of work relating to the registration of media types for languages that evolve. A new product page describing the plan for this work should be available by February, 2012.

Note that the product titles in the first column provide links to so-called "product pages", which have more detail about the goals, scope, deliverables, and schedule for each product.

No longer active

Metadata architecture for the Web (Several ongoing efforts are pertinent to this — note also that ISSUE-63 remains open, in part as an umbrella for those efforts. What we've "abandoned", at least for now, is the effort to do a comprehensive metadata architecture for the Web.)
HTTP Semantics: The TAG oversaw a subgroup with the informal name AWWSW (Architecture of the World-Wide Semantic Web) that met by phone and using email for several years. Significant progress was made in discussing a formal semantics for HTTP in particular, and on related issues. At its June 2011 F2F, the TAG decided to discontinue formal tracking of this as a TAG effort.
The TAG briefly considered starting a formal effort on HTML.next. At the 5 January 2012 F2F it was decided not, for the moment, to proceed. HTML.next was therefore removed from the under consideration list.
During 2011, the TAG attempted to frame a broad initiative under the tentative title "Privacy Friendly Web". A framework for a report was prepared but never elaborated. At it's 5 January 2012 F2F meeting, the TAG agreed not (for the moment) to do a major project on privacy. The TAG may or may not work on some particular technical issues that might help to address privacy concerns for the Web.
