=Web Schemas=

==Introduction==

This is the main Wiki page for W3C's [http://www.w3.org/2001/sw/interest/ Semantic Web Interest Group] ''Web Schemas'' task force. Amongst other roles, it serves as a public discussion forum for [http://schema.org/ Schema.org].

The taskforce chair is R.V.Guha (Google), assisted by [http://www.w3.org/wiki/User:Danbri Dan Brickley]

In scope include collaborations on mappings, tools, extensibility and cross-syntax interoperability. An [http://www.w3.org/wiki/Html-data-tf HTML Data] group is nearby (see also [http://lists.w3.org/Archives/Public/public-html-data-tf/ public-html-data-tf list]); detailed discussion about Web data syntax belongs there.

See the [http://www.w3.org/2001/sw/interest/webschema.html charter] for more details. 

The group uses the '''public-vocabs@w3.org''' mailing list

* See [http://lists.w3.org/Archives/Public/public-vocabs/ public-vocabs@w3.org archives]
* [http://www.w3.org/2011/webschema/track/ Issue Tracker] (organized into "Feedback on X" products/categories, where Xs are Schemas we're discussing)
* To subscribe, send a message to public-vocabs-request@w3.org with Subject: subscribe (see [http://lists.w3.org/ lists.w3.org] for more details).
* If you are new to the W3C community, you will need to go through the [http://www.w3.org/2002/09/aa/ archive approval] process before your posts show up in the archives.
* To edit this wiki, you'll need a W3C account; these are [http://www.w3.org/Help/Account/Request/Public available to all]

Groups who maintain Web Schemas are welcome to use this forum as a feedback channel, in additional to whatever independent mechanisms they also offer.

In particular, the Schema.org initiative has [http://blog.schema.org/2011/10/w3c-web-schemas-group-is-our-new-public.html adopted] this group as its primary public feedback forum. Others are invited to do likewise.
 
Any W3C-related questions, ask Dan Brickley (SWIG chair), c/o danbri@danbri.org

==Discussion Elsewhere==

For background discussion on this group, Schema.org and W3C's SWIG, the Oct 2011 [http://semanticweb.com/the-semantic-link-%E2%80%93-episode-11-october-2011_b23961 Semantic Link] podcast may be of interest.

The Dublin Core Metadata Initiative has a related task group working on [http://wiki.dublincore.org/index.php/Schema.org_Alignment Schema.org Alignment], alongside existing vocabulary collaboration work [http://dublincore.org/documents/dcmi-foaf/ with FOAF].

For schema.org there are discussions on various sites (unofficial; this group is the only place monitored by Schema.org team) :

==Markup examples==

This group is about vocabulary (schemas) rather than specific markup syntax details. However since syntax specs are evolving in parallel, there are often discussions that need to mix syntax and vocabulary issues.

* from structured-data.org, some [http://linter.structured-data.org/examples/ examples] showing RDFa 1.1 lite versions of Schema.org's Microdata samples
