Tag reference

This section lists the «mapping» from Photini’s field names (such as «Title / Object Name») to the EXIF / XMP / IPTC tags the data is stored in. The tag names are those used by the Exiv2 library. See http://exiv2.org/metadata.html for more detail.

As far as possible Photini follows the Metadata Working Group (MWG) Guidelines for Handling Image Metadata. These specify the mapping between tags in EXIF, XMP and IPTC, and say how software should reconcile any differences between information stored in equivalent tags.

Primary tags

These tags are where Photini stores its metadata. (IPTC tags are only used if they already exist in the file, in line with the MWG guidelines.)

Note that «Title / Object Name» and «Keywords» are not stored in EXIF. You may prefer not to use these fields to ensure compatibility with software that only handles EXIF.

Secondary tags

Photini may read information from these tags and merge it with information from the primary tags. These tags are deleted when the corresponding primary tags are saved.
