This article is devoted to two different generalizations of projective Boolean algebras: openly generated Boolean algebras and tightly σ-filtered Boolean algebras. We show that for every uncountable regular cardinal κ there are 2 pairwise non-isomorphic openly generated Boolean algebras of size κ > א1 provided there is an almost free non-free abelian group of size κ. The openly generated Boolea...

In large process deployments where an enterprise has to model and maintain a large number of processes that are specializations of each other it is advantageous to provide formal support for process specialization called process inheritance. A process inheritance model definition is introduced as well as a process definition language construct for defining process specialization.
