2.3.3.2. Application Definitions

A description of each NeXus application definition is given. NeXus application definitions define the minimum set of terms that must be used in an instance of that class. Application definitions also may define terms that are optional in the NeXus data file. The definition, in this case, reserves the exact term by declaring its spelling and description. Consider an application definition as a contract between a data provider (such as the beam line control system) and a data consumer (such as a data analysis program for a scientific technique) that describes the information is certain to be available in a data file.

Use NeXus links liberally in data files to reduce duplication of data. In application definitions involving raw data, write the raw data in the NXinstrument tree and then link to it from the location(s) defined in the relevant application definition.

Application definitions are grouped together based on the research fields where these are typically used. Definitions that address multiple research fields are listed in each category:

Atom Probe Microscopy

Diffraction Techniques

Electron Microscopy

Multi-Dimensional Photoemission Spectroscopy

Optical Spectroscopy

Scattering Techniques

Time-of-Flight Techniques
