Main Page

This wiki is for connecting the W3C communities (Web developers, implementers, people who make the W3C specifications). W3C has a formal track for making standards specifications. The specs answer a lot of questions, but not all of them. The wiki is used by many communities such as the Open Web Platform and the Semantic Web. You might want to contribute to W3C work.

Pages here have no formal status but may have WikiConsensus. Questions & answers here may be misleading, or just plain wrong. Or, they may be useful. You are welcome to add, fix, develop and rearrange topics.

The W3C Quality Assurance was a dedicated W3C activity from 2001 to 2005. It included work on the Markup validator, but also touched upon topics such as tracking issues and URI testing among others. W3C maintains a liaison with IETF to coordinate on technologies and specification related to the Open Web Platform.
