W3C Activities

W3C Activities are organized into groups: Working Groups (for technical developments), Interest Groups (for more general work), and Coordination Groups (for communication among related groups). These groups produce the bulk of W3C's results: technical reports, open source software, and services (eg, validation services). There are currently over thirty W3C Working Groups. To facilitate management, the Team organizes W3C Activities and other work into four domains:

Architecture Domain
The Architecture Domain develops the underlying technologies of the Web. Activities include:

The Document Object Model

Web Services, programmatic interfaces for application to application communication
