SDL 2005: Model Driven: 12th International SDL Forum, Grimstad, Norway, June 20-23, 2005, Proceedings [Paperback]

This volume contains the papers presented at the 12th SDL Forum, Grimstad, Norway. The SDL Forum was ?rst held in 1982, and then every two years from 1985. Initially the Forum was concerned only with the Speci?cation and Description Language that was ?rst standardized in the 1976 Orange Book of the Inter- tional Telecommunication Union (ITU). Since then, many developments took place and the language has undergone several changes. However, the main underlying paradigm has survived, and it is the reason for the success of the Speci?cation and Description Language in many projects. This paradigm is based on the following important principles of distributed - plications: Communication: large systems tend to be described using smaller parts that communicate with each other; State: the systems are described on the basis of an explicit notion of state; State change: the behavior of the system is described in terms of (local) changes of the state. The original language is not the only representative for this kind of paradigm, so the scope of the SDL Forum was extended quite soon after the ?rst few events to also include other ITU standardized languages of the same family, such as MSC, ASN.1 and TTCN. This led to the current scope of System Design Languages coveringallstagesofthedevelopmentprocessincludinginparticularSDL,MSC, UML, ASN.1, eODL, TTCN, and URN. The focus is clearly on the advantages to users, and how to get from these languages the same advantage given by the ITU Speci?cation and Description Language: code generation from high-level speci?cations.Language Issues.- ULF-Ware  An Open Framework for Integrated Tools for ITU-T Languages.- An Access Control Language for Dynamic Systems  Model-Driven Development and Verification.- Non-deterministic Constructs in OCL  What Does any() Mean.- Engineering Issues.- Integrating RT-CORBA in SDL.- Component Development: MDA Based Transformation from eODL to CIDL.- Service Discovery and Component Reuse with Semantic Interfalƒ
