2.3.3.3. Contributed DefinitionsΒΆ
A description of each NeXus contributed definition is given. NXDL files in the NeXus contributed definitions include propositions from the community for NeXus base classes or application definitions, as well as other NXDL files for long-term archival by NeXus. Consider the contributed definitions as either in incubation or a special case not for general use. The NIAC: The NeXus International Advisory Committee is charged to review any new contributed definitions and provide feedback to the authors before ratification and acceptance as either a base class or application definition.
