IPTC Extension metadata support (e.g. "artwork shown")
Does the metadata extraction from images include the IPTC Extension fields?
These fields include for example artworks and locations shown in a photograph.
Reference: IPTC Core & Extension
Where do I find the source code for that in the nuxeo repositories?
I do not believe those specific fields are included in the metadata extraction. Take a look at the nuxeo-platform-imaging-api and nuxeo-platform-imaging-core packages and search for IPTC and you will find the references/classes of interest. I ended up overriding the PictureChangedListener to extract all the metadata necessary for a media client – this also necessitated updating the underlying metadata-extractor library.
There was also a project for the Indianapolis Museum of Art … IMA on github
I am curious, whether they had a similar request.
