Hans and all, In the next days I will prepare some text,patch/patches and pictures(schemas) for this wiki page. One of the pictures will show the book`s original ideas and the other will show my personal vision of these entities and how they should be enhanced to fit best into the OFBiz project. I do not say that this(my) vision about the entities is the best way to go. After posting in wiki, I will wait for the community`s feedback and suggestions to make common decision.
Thanks: Valentina
