    Frameworks: the future of formal software development?
    SINNOTT, RICHARD (Elsevier Science, 1998)
    It could be argued that the primary issue to be dealt with in software engineering today is re-use of software. Current software development rarely, if ever, starts from nothing. Unfortunately, the same cannot be said for the development of specifications. To overcome this problem, various works have attempted to show how specifications can be built using architectural principles. We discuss one such approach in particular, the Architectural Semantics of Open Distributed Processing. We show the limitations of this work with regard to the architecting of specifications and propose a new approach, based on frameworks. To highlight the approach we use the work currently being done in the TOSCA project in its development of a service creation and validation environment for telecommunication services.

    Experiences of modelling and using object-oriented telecommunication service frameworks in SDL
    Kolberg, Mario ; Sinnott, Richard O. ; Magill, Evan H. (Elsevier, 1999)
    This paper describes experiences in using SDL and its associated tools to create telecommunication services by producing and specialising object-oriented frameworks. The chosen approach recognises the need for the rapid creation of validated telecommunication services. It introduces two stages to service creation; firstly a software expert produces a service framework, and secondly a telecommunications ‘business consultant’ who specialises the framework by means of graphical tolls to rapidly produce services. Here we focus on the underlying technology required. In particular we highlight the advantages of SDL and tools as well as issues and problems incurred.
