Over the last 5 years,
many of its members have been involved in the UML standardisation process
and have organised a variety of workshops and conferences relating the development
of UML as a precise modelling language.
Whilst some progress
has been made, there is still a significant way to go towards fully precise
modelling. MDA (the model-driven architecture - www.omg.org/mda) offers significant
hope in building some of the foundations for precision, and many pUML members
and past members are currently involved in this area of work.
