Hi,
When setting IPTC Category tag with exiftool, the string is limited to three characters.
Every other softwares I know allow reading and writing at least 18 characters (a string I actually use)
Would it be possible to up this limit in future updates ?
Because according to the the IPTC IIM Specifications (http://www.iptc.org/std/IIM/4.1/specification/IIMV4.1.pdf) (see page 31), it is supposed to be limited to three characters. You can work around this by using the -m option, which will allow exiftool to ignore the specification.
There is also the XMP:Category tag, which isn't limited to only three characters. You might want to check to see which tags your software is writing to.
If I recall, the original use of this tag was in news agencies and limited to some very specific codes. Though I can't seem to find any actual links on this at the moment.
Thanks, -m works fine !!
Just FYI, this feature is explained in the 3rd paragraph on the ExifTool IPTC Tags documentation (https://exiftool.org/TagNames/IPTC.html) page.
