Members

Alberto Aimar, John Apostolakis, Rene Brun, Dirk Duellmann, John Harvey, Vincenzo Innocente, Pere Mato, RD Schaffer, David Stickland, Lassi Tuura, Christian Arnault

Goals

For what concerns Software Architecture, look at the following:

Review what is going on in various corners - existing frameworks

Exchange experience - establish good design practices

Understand importance of interfaces - enabling code to be shared

Establish which foundation libraries we can work with

Assess impact of new languages e.g. possible evolution to Java

Review integration standards - assess current usage and potential impact

Agree on terminology, assemble bibliography, make a website,..

Identify the crucial issues that need to be made visible, where work is needed, where decisions have to be made and prepare to discuss in Marseilles
