Hi Pete. Isn't this what relationship does or could do?

Hi all, The other day I had an interesting idea for managing complex inter-object relationships in Zope3 in a way I haven't seen done before. I threw a blog up about it so I wouldn't forget it when the idea struck me (things I don't write down, I tend to forget, no matter how seeming important at the time). I wasn't going to mention it on the list immediately, because as with many ideas I get enthused about, after a day or two of thinking, I realize one of many different things about the idea. The realizations regularly include, but are not limited to, a) that it has been done already, b) that it doesn't solve a problem I'm likely to have more than once, or c) that it introduces more complexity into a given system than the original problem space contained. So, I waited on this one. And a few weeks later, it still seems like an interesting idea. But what I'd like is some commentary and feedback from other people in the Zope community, especially from anyone who may have pondered (or solved!) this kind of thing before. The post is located here: http://baldtrol.blogspot.com/2006/06/irelationshipmapper.html It is basically a statement of a way to manage non-containment relationships between ZODB persisted objects in a way that should not necessitate object-intrusive code. However, There may be complexities that I've neglected, or other extant solutions for this same kind of problem in Zope3 that I'm just unaware of. Any suggestions, comments, or thoughts on how to improve on this design would be more than welcome... I would like to start working on an implementation of this idea... I've done something like this on a smaller scale already, but would be very interested in hearing thoughts on this before I undertake the larger project. Thanks all! Pete
