  We investigate an abstract conceptualisation of DigitalEcosystems from a
computer science perspective. We then provide a conceptual framework for the
cross pollination of ideas, concepts and understanding between different
classes of ecosystems through the universally applicable principles of Complex
Adaptive Systems (CAS) modelling. A framework to assist the cross-disciplinary
collaboration of research into Digital Ecosystems, including Digital
BusinessEcosystems (DBEs) and Digital Knowledge Ecosystems (DKEs). So, we have
defined the key steps towards a theoretical framework for Digital Ecosystems,
that is compatible with the diverse theoretical views prevalent. Therefore, a
theoretical edifice that can unify the diverse efforts within Digital
Ecosystems research.
