How to edit NXtomo image key

"In this video we show you one dedicated interface to edit `image_key` of a specific NXtomo. This can allow user to ignore some frames (if image_key is set to zero) or fix some wrong image key."

How to use projections from an NXtomo to be used as (reduced) flats or darks

"In this video we show how to use frames contains in an NXtomo as flats then as reduced flats. The same process works for other manipulation (as creating reduced darks)"

ExPaNDS mapping dcat ontology and Nexus https://pan-training.eu/materials/expands-mapping-dcat-ontology-and-nexus Different communities have developed their terminology and are maintaining their metadata schemata or lists of vocabulary. In order to facilitate sharing of data across communities and allow collaboration between heterogeneous systems, interoperability of these vocabularies is required. In order to increase data interoperability and enable data integration, these vocabularies need to be semantically integrated with other vocabularies and their terms have to be aligned. This enables the development of a common shared vocabulary. expands, ontology, mapping, NeXus, DCAT, semantic integration, wp3-ExPaNDS PaN Community

ExPaNDS NeXusOntology https://pan-training.eu/materials/expands-nexusontology-machine-readable-ontology-of-the-nexus-definitions NeXusOntology: Machine-readable ontology of the NeXus definitions. The published ontology describes the NeXus standard, it does not define the standard. This ontology extracts information about NeXus classes and fields from NeXus nxdl definition files on the NeXus GitHub site. This project was undertaken under ExPaNDS WP3.2. The ontology is designed to fulfil several purposes. First, it creates unique identifiers for each of the NeXus fields which would normally exist only within the namespaces of the defining NeXus classes. This is the primary goal and provides PIDs for annotation and tagging. The second purpose is to allow, via separate ontologies, NeXus fields and classes to be mapped onto equivalent or related terms defined elsewhere. Finally, we hope that this ontology, when used with a tool such as Protege, will provide a useful 'NeXus Explorer' tool to gain a quick overview of NeXus with links to official NeXus documentation.
