Hi "leijunran" (please add your name to postings)
I quick outline of the technical design of the IPTC Core (and IPTC Extension) Schemas:
- In first place they define the semantics and names of properities
- each property may be implemented in differerent technical ways: either by the IPTC IIM (Information Interchange Model) technology or by XMP.
All formal details can be found in the specification document - you are referring to a guide to the user interface which is not made for technical implementations - download:
http://www.iptc.org/std/photometadata/2008/specification/IPTC-PhotoMetadata-2008_2.pdf
and check the corresponding Errata page at:
http://www.iptc.org/std/photometadata/2008/specification/PhotoMd2008Errata.html
- The spec table for each property has an XMP Implementation section which itself has a row "IIM mapping". There are two options for each property:
a) it is implemented in both XMP and IIM: then this "IIM Mapping" row shows the dataset number of the IIM property, e.g. for Intellectual Genre "2:04"
b) it is implemented only in XMP because there is no corresponding IIM property - and the development of IIM was stopped in 1997: then this "IIM Mapping" row is empty.
Btw: the IIM specs can be had from
http://www.iptc.org/std/IIM/4.1/specification/IIMV4.1.pdf
If you need more information please come back.
