Changes for April 2010¶
List of key changes for April 2010 major release of the ome-xml data model.
The new major release of the schema has a new namespace and all version numbers are reset to 1. As a major release, any file that validated correctly using the last major release will probably not validate correctly using this new release. Some files that failed to validate before will now be valid. It is important to update any file readers and writers to understand the changes.
The version number of all schema files is now 1.
This schema uses the new namespace
http://www.openmicroscopy.org/Schemas/[NameSpaceTitle]/2010-04/
For the OME schema
http://www.openmicroscopy.org/Schemas/OME/2010-04/
and the schema file is located at
http://www.openmicroscopy.org/Schemas/OME/2010-04/ome.xsd
