Relational Address Book

In the following document, I present both the need for a relational address book, and a concept for implementing one. As this is something I’ve been hoping for for a very long time, I have become ever more interested in seing something along these lines produced. As a first step in this direction, I have written this document. I am hoping for feedback to it, so that I can adjust my ideas to something that has a more universal appeal. And also, so that flaws in the concept can be recognized and fixed. So, without any further delay, if you’re interested in this, too, please read and respond.
