First, a brief bit of perspective on the role Catalysis has played in the UML.
UML 0.8 was released by Rational in October 1995, based on the work of Booch, Rumbaugh, and Jacobsen.
In Fall 1996, Microsoft and Hewlett-Packard joined the consortium of companies that was defining UML,
initiated by Rational. Microsoft brought some modeling requirements based on its COM model of interfaces
of components; HP brought a focus on re-use.
In Oct-Nov 1996, several other companies joined this consortium. Oracle came in with a particular interest in
the modeling of business processes and workflows. Texas Instruments software came in with an interest in
components and business modeling, and in Catalysis. MCI Systemhouse’s interest was distributed systems.
And ICON Computing joined this lofty team with its work on Catalysis. As a partner in defining the UML 1.0,
ICON brought a focus on several key elements of Catalysis: types (as distinct from classes), precise
specification of behavior, collaborations as definitions of multi-party behavior, refinement of models, and
frameworks as a means to abstract and apply recurring patterns in modeling. This technical contribution to
the UML team was largely done by Desmond D’Souza, with input from his Catalysis co-author, Alan Wills.
The UML 1.0 spec was submitted to the Object Management Group in Jan 1997, and accepted as a standard in
September 1997.
