gentoo@chymera.eu Horea Christian sci@gentoo.org Gentoo Science Project A Python library for maintaining and managing DANDI metadata schemata. The library helps create and validate DANDI schema-compliant metadata for Dandisets and assets. Every Dandiset and associated asset has a metadata object that can be retrieved using the DANDI API. This library uses Pydantic to implement all the metadata classes. Schemas are generated on schema modifications and placed into this repository. Dandischema generates JSON schema definitions and also an associated context.json file for JSON-LD compliance of the metadata models.
