How to enhance metadata quality for my tools, datasets, workflows ?

These automated validations leverage semantic web technologies and check that metadata use standards and recognized ontologies or controlled vocabularies.


First, embedded semantic annotations are extracted from web pages, forming a minimal knowledge graph. Then, this minimal knowledge graph is completed based on already deployed knowledge graphs (Datacite, OpenAire, WikiData). Finally, the resulting knowledge graph is tested to check that classes and properties are recognized through Linked Open Vocabularies (LOV), or Ontology Lookup Service (OLS)
