File Format Specifications
OME-XML
OME partners at Dundee develop and maintain the OME-XML schemas that represent the data model. The XML namespaces for the current schemas are located on this site. This also where the XSD files are available to download from.
http://www.openmicroscopy.org/Schemas/
OME-XML has its own site at http://www.ome-xml.org/ for documentation and development discussion.
Note: any schemas and documentation below http://www.openmicroscopy.org/XMLschemas/ is preserved for legacy support only. This includes the 2003FC schema used by the original OME server.
OME-TIFF
OME partners at LOCI have developed a variant of the OME-XML File specifically designed for data acquisition and storage. This format, called OME-TIFF, uses OME-XML in the standard TIFF header and stores binary image data in a multi-page TIFF file.
File Formats Samples
.ome Samples
-
min-sample-2008-02.ome
- sample created with dummy data to show the shape of a minimal file
-
max-sample-2008-02.ome
- sample created with dummy data showing at least one of everything in a file
.ome.tiff Samples
single-channel-2008-02.ome.tif - view embedded XML
- generated file with placeholder image in three different schemas. The tiff file has OME image frame.
There are further samples available direct from LOCI.
XSLT Transform Samples
There are two transforms available that convert between the hierarchical pre-July 2007 OME schema and a flat CA only representation of that schema. These are used as part of the import process by the OME Server and are no longer being maintained.
- From full OME to OME-CA: OME-CA2OME.xslt
- From OME-CA to OME: OME2OME-CA.xslt
