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.
