Chem-DCAT-AP: Extending DCAT-AP using LinkML in Layers

Presentation given at the Ontologies4Chem Workshop 2025. Abstract: We presented the DCAT-AP extension developed in a joint venture by NFDI4Chem & NFDI4Cat. This LinkML based, extended version of DCAT-AP can be used to provide domain specific metadata on datasets. We will demonstrate how this extension can be applied for any scientific domain due to its mapping to PROV-O, DCTerms and QUDT, as well as how it can be further extended easily to provide domain specific metadata schemata directly mapped to more domain specific terminologies on the example of chemistry and catalysis. --- This research was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), grant number 441958208 (NFDI4Chem) 441926934 (NFDI4Cat).
