Visio 2010 XML Schema Definition Released

Visio has published the XML Schema Definition (XSD) files for the Microsoft Visio 2010 XML Drawing (.vdx) format. This schema is also known as DatadiagramML. The .XSD files allow developers to better understand the structure of Visio XML documents and design solutions that work with the .VDX file format.

The DatadiagramML Schema for Visio 2010 consists of three .XSD files:

  • visio.xsd is the core schema used by Visio 2003 and later
  • visio12.xsd is the set of extensions used by Visio 2007 and later
  • visio14.xsd is the set of extensions used by Visio 2010

More information about the schema is available in the Visio 2010 XML Schema Reference on MSDN.
