  text: One future goal of service-oriented computing is to realize global markets
    of composed services. On such markets, service providers offer services that can
    be flexibly combined with each other. However, most often, market participants
    are not able to individually estimate the quality of traded services in advance.
    As a consequence, even potentially profitable transactions between customers and
    providers might not take place. In the worst case, this can induce a market failure.
    To overcome this problem, we propose the incorporation of reputation information
    as an indicator for expected service quality. We address On-The-Fly Computing
    as a representative environment of markets of composed services. In this environment,
    customers provide feedback on transactions. We present a conceptual design of
    a reputation system which collects and processes user feedback, and provides it
    to participants in the market. Our contribution includes the identification of
    requirements for such a reputation system from a technical and an economic perspective.
    Based on these requirements, we propose a flexible solution that facilitates the
    incorporation of reputation information into markets of composed services while
    simultaneously preserving privacy of customers who provide feedback. The requirements
    we formulate in this paper have just been partially met in literature. An integrated
    approach, however, has not been addressed yet.
