Welcome to the Shlaer-Mellor metamodel wiki!

The complete metamodel is beginning to take shape. Most of the loose ends are in the Action Subsystem at this point.

The current exercise is to parse Scrall action language from a variety of sources by hand. I'm doing this on a large Omnigraffle worksheet. The idea is to scan a chunk of existing Scrall, from the Elevator Case Study for example, and make sure that it is possible to account for all the parsed content somewhere in the action subsystems

In the meantime, feel free to browse at the construction underway. – Leon
