thanks Leo and Rob; right now this sounds like rocket science for me...
I will have to take a look at optilude's b-org tutorial but I really
have no brain for this now. what about using Sidnei's Marshall product?
at the end of the day what I want is a mechanism to import not only
images but also NITF files (XML dialect used to define the content and
structure of news articles also developed by the IPTC,
http://www.nitf.org/).
I don't want to create additional content types, I prefer to use Image
and News Item and decorate them with metadata.

I was wondering if there is a way to modify the marshaling of ATImage
content type in order to allow it to read the IPTC record embedded in
the image to create automatically the image with title and
description mapping the headline and caption fields.
we have been using a Python library called IPTCInfo to read and write
information inside JPG images successfully.
I would suggest you create a new product with a new ATImage subclass,
wherein you override the setImage() mutator to call the original one and
then use IPTCInfo to also set the other attributes. Then you need to
change
the mimetypes registry to point to your type instead of ATImage.
Alternatively, you could either monkeypatch the ATImage .setImage()
(which
is ugly but works when in a hurry) or listen to ObjectModifiedEvents for
ATImages and set the other attributes with the IPTC information.
the third of these choices seems preferable, IMO. it would also be
possible to define a new marker interface (IIPTCImage, possibly) and
declare this to be implemented by the ATImage class via ZCML. you could
define adapters, listen to events, and declare new views based on the
marker interfaces. and you could re-use the same marker interface for
news items, or anything else that may have an ImageField, w/o needing to
subclass from ATImage.
