Metadata
PhotoPrism aims to extract as much metadata from your original files as possible.
This is an ongoing task. If you are using certain standard exif or xmp fields that are not supported yet, feel free to open an issue or pull request.
PhotoPrism does not yet write back changes to EXIF or XMP (see discussion).
We want you to have access to your metadata independent from PhotoPrism or its database, that's why we create human-readable YAML backups with metadata you add to your files using PhotoPrism.
Supported Metadata Tags¶
PhotoPrism uses exiftool to extract metadata from different file formats like EXIF, XMP, IPTC and more. We additionally parse XMP.
This table gives an overview what tags from exiftool or XMP are mapped to which fields in PhotoPrism.
In case a field is populated with data from xmp, the data from xmp is the single source for this field. Meaning e.g keywords from xmp overwrite other keywords coming from PhotoPrism such as colors or keywords derived from folder names.
