This paper presents a Model Driven Development (MDD) approach to the automated creation of the Diagnosing Services and integrating them into the system. The outline of the method is as follows. BPEL models of the services are transformed to Deterministic Automaton with Unobservable Event representations using the MDD transformations. Then, relying on Discrete Event System techniques Diagnosers Automaton for the Deterministic Automaton representations are created automatically. Finally, the Diagnosers Automaton is transformed into a new BPEL representation, which is integrated into the original architecture. The proposed approach is implemented as an Oracle JDevlopers plugin. To evaluate the presented method, a case study involving a Right-First-Time failure scenario motivated by telecom application is used.10aBusiness process execution language10aOracle JDevlopers10aWeb services1 aAlodib, M.1 aBordbar, B.1 aMajeed, B.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-79960673085&partnerID=40&md5=01e27ad877cad334f9f50bb5f59cbeff01751nas a2200241   4500008004100000245008100041210006900122260000900191300001200200490000600212520099800218653002501216653001401241653002401255653001501279653001701294653001701311100001501328700001601343700001501359700001801374856011701392       2006                        eng d00aSemantic indexing and hyperlinking of multimedia news: The RitroveRAI system0 aSemantic indexing and hyperlinking of multimedia news The Ritrov  c2006  a63 - 720 v43 aWeb services tend to offer functional and non-functional requirements and capabilities in an agreed, machine-readable format. The target is to provide automated services for discovering, selection and binding of information as a native capability of middleware and applications. However, the major limitations are due to the lack of clear and processable semantics. In this paper, a system, RitroveRAI, addressing the general problem of enriching a multimedia news stream with semantic metadata is presented. News metadata are explicitly derived from transcribed sentences or implicitly expressed into a topical category automatically detected. The enrichment process is accomplished by aligning individual audiovisual segments with news or journal articles reachable trough the Web. This distributed process designed for RitroveRAI enables several extensions in light of large scale and public access performance as suggested in the discussion of the evaluation results of our current system.10aHyper link structure10aMeta data10aMultimedia indexing10aRitroveRAI10aSemantic web10aWeb services1 aBasili, R.1 aCammisa, M.1 aDonati, E.1 aMoschitti, A.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-33748253466&partnerID=40&md5=05e5487b09fcb109fd3c282449982ec4
