DANDI schema
DANDI Archive Metadata Schema
The metadata models of the DANDI neurophysiology archive. Pydantic models in the dandischema library define Dandiset and asset metadata; versioned JSON Schemas plus a JSON-LD context are generated from them and published in the dandi/schema repository. The library also converts Dandiset metadata to DataCite for DOIs.
