The OME-XML Java library is a collection of Java packages for manipulating OME-XML metadata structures. The OME-XML Java library's metadata processing facilities form the backbone of the :bf:`Bio-Formats <>` library's support for OME-XML conversion.
The ome-xml artifacts are hosted on the
Maven Central Repository under the group org.openmicroscopy and distributed under the
2-Clause BSD license.
To use, add ome-xml.jar to your classpath or build path.
Refer to the :javadoc:`online API documentation <>`, specifically the ome.xml.* packages. For an example of usage, see the :bf_source:`Screen Plate Well unit test <components/formats-bsd/test/loci/formats/utests/SPWModelMock.java>`.
The OMENode is the root ("OME") node of the OME-XML. Each XML element
has its own node type (e.g. "Image" has ImageNode) with its own
accessor and mutator methods, to make navigation of the OME-XML
structure easier than it would be with a raw DOM object. However, there
are some limitations to what can be done with the API. If your
application needs access to a node's backing DOM element to work with it
directly, you can call getDOMElement() on a node.
The OME-XML Java library is an open source project—the source code is freely accessible via the https://github.com/ome/ome-model Git repository.
