A Python library for maintaining and managing DANDI metadata schemata. The library helps create and validate DANDI schema-compliant metadata for Dandisets and assets.

To use: pip install dandischema

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.

• models.py - contains the models and any changes should be made there
• metadata.py - contains functions for validating, migrating, and aggregating metadata
• datacite.py - converts the Dandiset metadata to a Datacite metadata structure

The generated JSON schemas can be used together with VJSF to create a UI for metadata modification. The DANDI Web app uses this for Dandiset metadata modification.
