The Jewels Application Framework is intriguing. I've toyed around with code to create business logic that uses collection and item classes to handle object/attribute validation, attribute setting and getting, etc, through the definitions of records.

I would like to take a look at some of the sample code. The Jewels site link for downloading code is broken. Where can I send requests for sample code?

Do you know of any other modules that attempt to handle object persistance using databases in this way?
