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 Overview of components changed ------------------------------ - schema cleanup - units - ROI changes - SPW changes - Filter changes Schema cleanup ^^^^^^^^^^^^^^ The following legacy objects have been removed: - :file:`AnalysisChain.xsd` - :file:`AnalysisModule.xsd` - :file:`CA.xsd` - :file:`CLI.xsd` - :file:`DataHistory.xsd` - :file:`MLI.xsd` - :file:`STD.xsd` This required the removal of references to them from ``ome.xsd``; the removal of ``CustomAttributes`` from OME, Image and Dataset nodes; and the removal of ``SemanticTypeDefinitions`` from the OME Node.
