The proper tag for IPTC data is 33723. It is not yet included in the Tag Reference. I will do so first thing.

Done. See http://www.awaresystems.be/imaging/tiff/tifftags/iptc.html

Best I could find on the DataType, BYTE, LONG, and ASCII all seems possible. That is suspicious, at the very least, especially with byte order issues in mind. If anyone can provide better information, please do so.

Libtiff is using LONG.

Also, not being familiar with IPTC, my best description is 'metadata'. If anyone is more knowledgable and able to make a small list of most common/usefull fields in this metadata, that then describes the tag a lot better, or otherwise better define the tag, please let me know.

Metadata is good.
