Metadata Extraction

Metadata Extraction

When you upload a file to your Permanent.org archive, we use select metadata embedded within the file to populate our Permanent metadata fields. If you are interested in using this feature to populate Permanent metadata fields, the following article explains how the Permanent system reads, extracts, and uses embedded metadata to populate Permanent fields. 

In general, the Permanent system prioritizes IPTC fields within the IIM data block for all metadata fields. If no IPTC fields are present in the file, the system will look for relevant EXIF Fields for the Permanent metadata field. If neither are present, nothing will be populated for the Permanent metadata (except for the Name field, which will be populated with the file's name without the extension).

Any metadata not extracted for use in Permanent metadata fields will be retained in the original file.

We currently do not support writing Permanent metadata back to downloaded files from your archive, so any metadata changes you make within Permanent will not be embedded into your files. We are working on this feature, so check back soon!
