ABSTRACT
A method for determining integrity in an evolutionary col laborative information system is provided. The method involves recursivel de?nin interaction of each com onent
ensembles that resgects product and technology inforrliiation
for identifying credentials on components and constraints on
’
component interactions. Constraints are explicitly de?ned as
