View source for Main Page

This wiki is for connecting the W3C communities (Web developers, implementers, people who make the W3C specifications). [http://www.w3.org/ W3C] has a formal track for making [http://www.w3.org/TR/ 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 [[How To Contribute|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.

== [[Open Web Platform]] ==
* You might be interested in [[HTML/Training|learning HTML]] or have a reference about [[HTML/Elements|HTML elements]].
* The W3C [[Quality Assurance]] was a dedicated W3C activity from 2001 to 2005. It included work on the [[MarkupValidator|Markup validator]], but also touched upon topics such as [[TrackingIssues|tracking issues]] and [[UriTesting|URI testing]] among others. W3C maintains a [[IetfW3cLiaison|liaison with IETF]] to coordinate on technologies and specification related to the [[Open Web Platform]].

==Specifications==
See [http://w3.org/TR current specs]. Work being done to improve specs in general:
* [[SpecProd]] - an effort to [[restyle]] spec content design.
* [[Spec Advancement]] - proposals for accelerating spec advancement.

== [[Evolution]] ==
An attempt to round up discussions about extensibility, versioning, naming, identifiers, registries, standards process.
