Vocabulary
Neurobagel
Neurobagel data model and vocabulary
An RDF vocabulary (nb:) and a JSON Schema for data dictionaries that harmonise participant-level metadata (age, sex, diagnosis, assessments, imaging modality, processing pipelines) by annotating BIDS participants.tsv columns with SNOMED CT, NCIt and NIDM terms. The resulting graphs power Neurobagel's federated search across datasets.
