| Description | The PaNET ontology provides a taxonomy and thesaurus of photon and neutron (PaN) experimental techniques, based mainly on accelerator-based light sources and neutron facilities. The primary use of the ontology is to enhance the FAIRness of PaN data catalogues services. The ontology defines specific techniques in terms of more general technique classes and provides synonyms and references. |

Photon and Neutron Experimental Techniques: An ontology of techniques within the photon and neutron (PaN) domain.
Purpose
The main purpose of this ontology is to provide a controlled vocabulary, global PIDs and annotations
for photon and neutron techniques, to support PaN FAIR data catalogue functionality.
Design philosophy
In the original version of the ontology, everything is a class and all classes are techniques. Object property relations
are implied but not formalized in this version. Subclass/superclass relationships and intersections are
used to define specific technique classes in terms of broader superclasses. This is seen as a key
requirement in order to carry out catalogue searcher for broader concepts, for example.
The ontology has since been restrucred to include both technique classes and specifier classes. The relationships between the two are also made explicit and formalized in the form of Object Properties. The specifier classes were created by identifying technique classes that act as umbrella terms. These techniques are defined using object properties and specifiers. The rest are defined in terms of other techniques using a mix of subclass and equivalence axioms.
This project was undertaken under ExPaNDS WP3.2 (https://expands.eu/)
The ontology is can be found here: https://github.com/ExPaNDS-eu/ExPaNDS-experimental-techniques-ontology
The restructuring of the ontology is detailed in a paper: https://doi.org/10.1107/S1600577525005272
Photon and neutron PaN ontologies developed under ExPaNDS are documented here: https://doi.org/10.5281/zenodo.4806026
