Technical Architecture Group Update
Technical architecture is about interfaces, system design, principles & connecting people:
cross-cutting concerns.
What is the TAG?
Chartered in W3C process to:
-
document and build consensus around principles of Web architecture and to interpret and clarify these principles when necessary;
-
resolve issues involving general Web architecture brought to the TAG;
-
help coordinate cross-technology architecture developments inside and outside W3C.
What does that mean?
-
Write architectural documents: findings, principles & guidelines;
-
Review new specifications & help where we can;
-
Work with others to identify key emerging topics;
-
We don't write standards.
