How Permanent.org Reads Embedded File Metadata
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.
At this time, Permanent is unable to read and extract metadata from TIF files. We are working on improving this feature to include more file types, so check back soon.
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).
IPTC Field (Priority)
EXIF Field (Second Priority)
Defaults to the upload file name (without the extension) if no IPTC or EXIF values are present
|(In order of priority):|
GPSTimeStamp + GPSDateStamp
|Calculated from GPSLatitude + GPSLongitude and run through Google Maps API||None|
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
