    Semantic technologies – especially for symbolic reasoning and complex event processing – are particularly interesting to be employed on embedded controllers for various industrial applications such as diagnostics of technical devices to reason about sensor events. However, these technologies are typically tailored towards common PC infrastructure and are thus not readily available on embedded platforms. In this paper, we present a proof-of-concept implementation of a technology stack for semantic complex event processing on the Gumstix embedded platform and report on first experimental results about memory consumption.

    Ontology based specification of web service policies
    (Informatik 2004, Informatik verbindet, Band 2, Beiträge der 34. Jahrestagung der Gesellschaft für Informatik e.V. (GI), 2004) Grimm, Stephan; Lamparter, Steffen; Abecker, Andreas; Agarwal, Sudhir; Eberhart, Andreas
    An ever-growing number of XML-based languages are used to describe Web Service related issues such as security (WS-Security Policy), access control (XAC-ML), or privacy (P3P-WS). While it is desirable to specify policies in a declarative way, these languages expose great diversity in both syntax and semantics making it hard to realize a unified system. Our contribution to this problem is twofold. First, we present an expressive formal notation for policies. Second, we show how requester-, provider-, and third-party policies can be used for choosing a suitable service while making sure that all relevant policies are obeyed.
