Technical Architecture Group (TAG)
What Is The TAG?
The TAG is a special working group within the W3C, chartered (under the W3C Process Document) with stewardship of the Web architecture.
As outlined in our charter, there are three aspects to this mission:
- to document and build consensus around principles of Web architecture and to interpret and clarify these principles when necessary;
- to resolve issues involving general Web architecture brought to the TAG;
- to help coordinate cross-technology architecture developments inside and outside W3C.

Meetings and Mailing Lists
- The TAG holds a weekly teleconference on Thursdays at 13:00
Boston time. The agendas are posted ahead of time on our Wiki.
and are announced on the www-tag mailing
list at least 24 hours in advance. Draft minutes follow within a day or
two, and are posted on the same list.

- www-tag (archive) is the
TAG's public list where it conducts work and engages in discussions on its
work with the community. Use W3C mailing list
mechanics to subscribe etc.
- public-tag-announce (archive,
RSS
feed) is used for announcements from the TAG of minutes, meeting
summaries, findings, new issues, resolved issues, and drafts of
architecture documents. Note:
Announcements will also go to www-tag.
- public-webarch-comments (archive)
is used for review comments on the Architecture Document.
The W3C
archive editing policy is quite conservative; W3C will remove a messge to
these lists only in extreme circumstances.
Current Work
The TAG is currently in a transitionary phase. Some of its work has been reflected in public product pages that have listed
significant ongoing TAG projects. However, the TAG is experimenting with moving some of its work to GitHub. The TAG repositories on GitHub may be found under the w3ctag organization.
The TAG tracks long running issues and detailed actions using the W3C Tracker System. In addition, as part of our transfer of some ongoing work to GitHub, we are tracking some issues and holding some discussions on GitHub's issue tracker.
The TAG issue list shows issues that the
TAG plans to address; by charter, issues are
addes to this list by majority vote.

About the TAG: Charter, History
The TAG charter was added to W3C process July 2001:
W3C has created the TAG to document and build consensus
around principles of Web architecture and to interpret and clarify these
principles when necessary, to resolve issues involving general Web
architecture brought to the TAG, and to help coordinate cross-technology
architecture developments inside and outside W3C.
Our work from 2001 to 2004 culminated in:
- Architecture of the
World Wide Web, Volume One W3C Recommendation 15 Dec 2004
Abstract:
The World Wide Web uses relatively simple technologies with sufficient
scalability, efficiency and utility that they have resulted in a
remarkable information space of interrelated resources, growing across
languages, cultures, and media. In an effort to preserve these properties
of the information space as the technologies evolve, this architecture
document discusses the core design components of the Web. They are
identification of resources, representation of resource state, and the
protocols that support the interaction between agents and resources in
the space. We relate core design components, constraints, and good
practices to the principles and properties they support.
