Subject: Domain Model for Identity Management (Standard Schema ERD).
Jeff Bohren asked me to provide an Entity-Relationship Diagram (ERD) for the entities we've been discussing as part of the standard schema for SPML. I'm really glad that he did, because re-thinking those entities and relationships was a good exercise. I found that I went further than before, and I'm very interested to see whether we agree (and the extent to which we can agree) on this domain model. Most of this domain model is the same as it was before, although it is perhaps clearer when properly articulated as an ERD with ordinality, cardinality, direction and so forth. Person and Account are the same; Group, Organization and Role are the same. The area that is new has to do with Role and Type-of-Account. A Role may imply any number of types of account for a host. Each type of account may confer privileges on that host. I'm afraid that I may miss today's meeting. (Unfortunately, I have a conflict.) However, I'd be very excited to take questions and comments on the list. Once everyone's had a chance to read it, we can decide whether to discuss it during the next call. (If everyone hates it, we can decide whether to back up and revert to the areas previously defined. If everyone basically likes it, we can discuss details like the specifics of entities, relationships, attributes and names.) I've attached a draft of the document (with everything removed except the domain model sections). This is an OpenOffice 2.0 document, which may be weird for some people, so I've also attached it as a PDF. Hopefully one format or the other will work for everyone. Gary
