About IPTC metadata
In Aperture, you can import and export IPTC metadata for a photo in an XMP sidecar file. XMP
sidecar files are XML files that accompany each photo containing IPTC and other metadata
associated with the photo. Any field containing information in the IPTC Core metadata view for
a selected photo version can be exported to the XMP sidecar file for that version. The IPTC Core
metadata view is compliant with the IPTC Core specification version 1.0. For more information
about choosing the IPTC Core metadata view, see
Modify metadata in the Info inspector and
on page 198. For more information about exporting XMP sidecar files, see
on page 358. For more information about the IPTC Core specification,
go to
If you intend to export your keywords as IPTC metadata, make sure each keyword entry is no
more than 64 characters long. Keyword entries longer than 64 characters may not be displayed
properly in other IPTC editors or operating systems.
