Abstract: Different clients have different needs, therefore adaptability and variability are crucial properties for service compositions to fit those various requirements. This is hard to achieve in a cross-organizational context where services are implemented and deployed by different organizations (e.g. companies, administrative domains,...): a feature, for example security, cannot be condensed into a single module that is applicable to all the different services. This paper proposes an aspect-based variability model for representing cross-organizational features in service networks such as systems of systems or service supply chains. We argue that cross-organizational features should be managed in a multi-layered architecture, distinguishing between policy and mechanism. Such multi-layered architecture is completely lacking in AOSD currently. Based on this tenet, we first describe a technology-independent feature ontology that is well-defined for a domain or a specific service network and map it to an aspect-based feature implementation.
