Brooklyn Museum object data is available via the Open Archives Initiative Protocol for Metadata Harvesting. Harvesters are required to carefully read the OAI Guidelines for Harvester Implementers.
Note that special api-keys are required. You must use a special OAI-enabled api-key to harvest. If you have an existing API key, you'll need to re-register for an alternate OAI key. We regret putting up this barrier but we feel api-keys are necessary to mitigate abuse. Go here to request a special OAI api-key.
The complete protocol specification should be reviewed before beginning work.
