  - 'Whenever customers have to decide between different instances of the same product,
    they are interested in buying the best product. In contrast, companies are interested
    in reducing the construction effort (and usually as a consequence thereof, the
    quality) to gain profit. The described setting is widely known as opposed preferences
    in quality of the product and also applies to the context of service-oriented
    computing. In general, service-oriented computing emphasizes the construction
    of large software systems out of existing services, where services are small and
    self-contained pieces of software that adhere to a specified interface. Several
    implementations of the same interface are considered as several instances of the
    same service. Thereby, customers are interested in buying the best service implementation
    for their service composition wrt. to metrics, such as costs, energy, memory consumption,
    or execution time. One way to ensure the service quality is to employ certificates,
    which can come in different kinds: Technical certificates proving correctness
    can be automatically constructed by the service provider and again be automatically
    checked by the user. Digital certificates allow proof of the integrity of a product.
    Other certificates might be rolled out if service providers follow a good software
    construction principle, which is checked in annual audits. Whereas all of these
    certificates are handled differently in service markets, what they have in common
    is that they influence the buying decisions of customers. In this paper, we review
    state-of-the-art developments in certification with respect to service-oriented
    computing. We not only discuss how certificates are constructed and handled in
    service-oriented computing but also review the effects of certificates on the
    market from an economic perspective.@eng'
