Dave Carlson on UML derived from schemas

Subject:   UBL update: Dave Carlson on UML derived from schemas

Despite my doubts about the immediate utility of XML schemas generated from UML representations of business models, I've wondered for a while now whether UML might not be a useful way to represent the information models expressed by XML schemas; a lot of people seem to like this form of visualization. Maybe we could generate UML models of all the xCBL 3.0 schemas for the benefit of people who like to work this way. Such a capability might also help convey input from UBL to the Core Components work. Dave Carlson has been looking at XML to UML conversion recently and is, at my request, willing to share his work with us at the upcoming UBL meeting in Menlo Park.

Our agenda for the plenary meeting 29 October calls for a UBL Group wind-up from 10 to noon and then an OASIS UBL TC meeting from 2 to 5 p.m. The room we're meeting in is directly above a cafeteria, so I thought it might work out well to schedule Dave for the main meeting room from 12:30 to 2 and let everyone who's interested bring lunch back upstairs from the cafeteria to hear him. If enough people want to continue the discussion when Dave's done with his presentation, we'll schedule a breakout session on tools for one of the days devoted to committee meetings.

Below is the title and abstract of the talk Dave will be giving us 29 October. You can find the updated meeting agenda at:

Extracting UML Conceptual Models from Existing XML Vocabularies
Dave Carlson, 29 October 2001 at the UBL Meeting in Menlo Park

This talk will review specific examples of reverse engineering UML conceptual model diagrams from several xCBL SOX modules, e.g. Catalog, Order, TradingParty, and Auction. The goal of this prototype work is to extract an accurate vocabulary structure that is independent of the schema implementation language. The resulting UML models can be more easily reviewed, refined and submitted as an initial library of ebXML Core Components.
