Forgive me everybody for the question, maybe I'm really ignorant on
UML, maybe is a FAQ... :(

How can GOOS diagrams describing AuctionSniper system (for example fig
13.1 on page 125) be defined in UML?

Are they _not_ UML?

Thank you

They are not UML. The circles are objects, the sticky-out "T" shapes
are interfaces of an object.

As far as I can recall, UML doesn't have an equivalent notation. You
can represent interfaces implemented by a class in a static structure
diagram with little lollipop shapes, and represent objects as rounded
rectangles in a dynamic structure diagram, but cannot put lollipops on
rounded rectangles.

Next question, does it matter to you or were you just clarifying?

It matters to me, Steve :) because I could not find such notation in
"UML distilled" diagrams.

I particularly like the sticky-out "T" shapes for interfaces of objects.
Congratulations for the eccellent book!

We can't take credit for it. The notation comes from RM-ODP (the ISO &
ITU reference model from open distributed processing) and, before
that, the ANSA project (http://www.ansa.co.uk/).
