Eric Schiller has announced CaXML, a proposed XML specification for chess games.

This proposal has been made in the hope of bringing some standardization to the storage of chess games in databases. It also hopes to allow more sophisticated presentation in the latest generation of browsers, preserve human readability of the data and support clean conversion of PGN (Portable Game Notation) files to CaXML.

Criticisms and comments on the proposal are welcome and sample files, stylesheets and the latest draft DTD are provided on the Chess City web site. A schema for the format is planned.

The CaXML format may also provide useful information for the development of XML formats for other games.

CaXML is open-source, released under the GNU Public License.
