Versioning Multimodal Data: Metadata & Beyond

Talkat PyData Virginia 2025 · 2025-04-18..04-19· [databases, developer-experience]
slides:none on file

The DVC team argues that multimodal needs a metadata-first versioning approach because files are heavy (megabytes to gigabytes) and datasets scale to thousands to millions to billions of files. A prototype called Data Chain serializes rich metadata with Pydantic models into a database, supports incremental updates (compute only changed items), exposes dataset history (nine demo versions) and enforces atomic dataset versions so sharing and queries work efficiently and the demo workflows succeed.
