This JSON lists the metadata types Lightroom manages for photos, from creator details to location info, detailing each key with its data type and description. The photo:getFormattedMetadata(key) function in the Lightroom SDK retrieves this metadata in a user-friendly format for display, mirroring Lightroom's layout, rather than for parsing.
