In the absence thereof, I have looked at LibTiff as one of the secondary source. LibTiff as a secondary source is what moved me to including LONG as one of the datatypes, for now. Other secondary sources mention BYTE and ASCII. With byte order issues in mind, the combination of these types is very suspicious, as I wrote before, which increases the need for a source with specification value. > > Also, not being familiar with IPTC, my best description is 'metadata'.

Metadata is mighty vague, and would equally well cover a handfull of other tags. A small list of most common/usefull fields remains desirable as a more helpfull tag description.
