I've just updated the demo into http://issues.apache.org/jira/browse/TUSCANY-751
Please review by unzip http://issues.apache.org/jira/secure/attachment/12342135/NewSdoOverview3.zip and use a browser to open sdo_index.html to start fresh (click the bottom link to sdo_uml.html) or sdo_uml.html to look at the change directly. Thank you Haleh for initiating the whole effort and suggesting an example into the introduction (sdo_uml.html). Here's the change: Here's an example. DataObject "Order" is wrapped inside a DataGraph. "Order" has a simple Property "number" whose type is String, as well as a containment DataObject Property "items" whose Type is "OrderItem" with multiple cardinality and "addresses" Typed many "OrderAddress". "OrderItem" has a non-containment DataObject Property "address" whose Type is "OrderAddress". (A diagram has also been added) Let me know your inputs and I'll incorporate them. Thanks. -- Yang ZHONG
