Hi!

I'd like to develop a small application with Magma and seaside (for more 
information: http://swiki.squeakfoundation.org/sea/90 ). I'd like to 
know if I got the following things right:

I have a class "DIADataHolder" (DDH). At the moment, it is the point 
where I store various collections. Later, I plan to switch to Magma for 
persistence.

Say, I have a collection, where I store articles. I have an lister class 
how shows this collection to the user an gives him the possibility to 
edit a particular article. Is it right to open a session, get the 
collection, begin a transaction on opening of the editor and to commit 
it on save? How do I disconnect a session when using seaside (where it 
is not guaranteed that the user presses the 'quit' button)?

What, if two users could work on the same collections?

Is there a reason for MagmaCollection not having a "fullblown" 
Collection interface (like "do:", "addAll:")?

Help or pointers to faq's appreciated (I've read "Getting Started with 
Magma", "Magma programming guidlines" and "About Magma Collections".

Regards, Markus
