The Städel Museum uses the OAI (Open Archives Initiative) interface for data interchange and synchronization. The metadata is regularly updated and can be viewed or harvested. The interface features two different metadata formats: first, a significantly reduced compressed format to assist in identifying the objects with Dublin Core, and, second, LIDO (Lightweight Information Describing Objects) for descriptive metadata.
The metadata is available under the license CC0 1.0.
