The W3C Technical Architecture Group (TAG)

Introduction to 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 its 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.

See the TAG current work page for details of how to work with it, upcoming events, and its publications.
