    Finding trading partners to establish ad-hoc business processes
    ( 2002)
    Wombacher, A.

    Mahleko, B.
    Enabling technology for realizing ad-hoc business processes currently is becoming more and more popular, like for example web services. Ad-hoc business processes are semantically characterized by a description of the exchanged messages and by the potential message sequences. These semantic meta-data are required to enable efficient and precise searching and finding of potential trading partners. Based on the experience of current web technology, manual maintenance of meta-data is neglected by most editors, therefore the meta-data must be generated automatically. Within this paper, we propose a method to derive a specification of potential message sequences based on a private workflow model. Further, we describe an algorithm for matchmaking of message sequence specifications as part of a search engine for ad-hoc business processes.

    Modelling the ICE standard with a formal language for information commerce
    ( 2001)
    Wombacher, A.

    Aberer, K.
    Automatizing information commerce requires languages to represent the typical information commerce processes. Existing languages and standards cover either only very specific types of business models or are too general to capture in a concise way the specific properties of information commerce processes. We introduce a language that is specifically designed for information commerce. It can be directly used for the implementation of the processes and communication required in information commerce. We demonstrate the use of the language by applying it to an important standard for specifying information commerce processes, the ICE Information and Content Exchange protocol [ICE1]. By doing so we also illustrate the benefit of using formal specifications for information commerce processes allowing to capture informal specifications, like ICE, in a concise way.
