IPTC Announces New Properties in Photo Metadata to Make Images More Accessible


The latest version of the International Press Telecommunications Council (IPTC) Photo Metadata Standard includes two new properties: Alt Text (Accessibility) and Extended Description (Accessibility). These will make it easier for software companies, publishers, and website developers to make websites and electronic publications more accessible.

Thanks.  These are already included in the current version of ExifTool.

Link to the IPTC Core tags.  I'm assuming that the tags in question are AltTextAccessibility and ExtDescrAccessibility.  Also assuming that the tags were added in version 12.33.

[Neal Krawetz]

As far as I can tell, AltTextAccessibility and ExtDescrAccessibility are only defined for use within an XMP recpord. They do not have IPTC IIM identifiers.

At long as it's in the XMP, it's just handled as text from the XMP parser.
(I don't think the list of hard-coded IPTC IIM identifiers hasn't changed since 2004.)

[Phil Harvey]

Yes, older versions of ExifTool will read these tags, but you need 12.33 or later (or work up your own config file) to be able to write them.
