This Dataverse v.5.3 release uses SKOSMOS as default protocol and supports ontologies provided by SKOSMOS and CESSDA Controlled Vocabulary Service. The functionality was developed by Data Archiving and Networked Services (DANS-KNAW) and funded by Social Sciences and Humanities Open Cloud (SSHOC) project.
Warning: it has experimental status as this functionality isn't merged to the master branch and intended for the testing purposes! Please find more information in the Pull Request IQSS/dataverse#7712.

Configuration
Download configuration files and apply sql statements to update Dataverse database and change the order of the metadata fields linked to controlled vocabularies. It should be Vocabulary, Term, VocabularyURI:
psql dvndb -f cv-update.sql
Warning: dvndb is postgresql database, it can be different in your installation.
Upload new metadata schema available for the testing purposes:
curl http://localhost:8080/api/admin/datasetfield/load -H "Content-type: text/tab-separated-values" -X POST --upload-file ./cvocdemo.tsv
Download and update controlled vocabularies supported by Dataverse:
curl -H "Content-Type: application/json" -X PUT --data-binary @cvoc-conf.json localhost:8080/api/admin/settings/:CVMConf
How to test controlled vocabularies support
You have to edit your sub dataverse and enable cvocDemo Metadata schema in the settings. Then in dataset form you can find "Vocabulary" and "Term" fields linked to SKOS (Simple Knowledge Organization System) framework called SKOSMOS http://skosmos.org. By default Dataverse uses its protocol to connect to any SKOSMOS API and can do lookup for the suggested terms in the selected ontologies. The specification of the protocol available in SKOSMOS API https://api.finto.fi/doc/.
If you need to support another protocol, DANS-KNAW has developed a simple middleware service called Semantic Gateway https://github.com/Dans-labs/semantic-gateway. The default list of available controlled vocabularies can be easily extended with other ontologies:
- Unesco
- Wikidata
- MeSH (Medical Subject Headings)
- Thesaurus (INRAE, Paris)
- IPTC (International Press Telecommunications Council)
- Agrovoc (controlled vocabulary of the Food and Agriculture Organization (FAO) of the United Nations)
- Fächersystematik (Fächersystematik Hochschulbildung in Deutschland)
