    Resoning About TCOZ
    (2002-03-01T00:00:00Z) Jing Song DONG; Jing SUN
    Timed Communicating Object Z (TCOZ) semantically and syntactically blends Object-Z with TCSP. TCOZ can capture the data/state and real-time interactions of system components. TCOZ preserves in large part both the syntax and semantics of the individual notations and hence can potentially benefit from existing reasoning systems of the individual notations. This paper extends and links the Object-Z and TCSP proof systems for reasoning about TCOZ models.

    Semantic-Web for Extending and Linking Formalisms
    (2002-03-01T00:00:00Z) Dong Jing SONG; Jing SUN; Hai WANG
    The diversity of various formal specification techniques and the need for their effective combinations requires an extensible and integrated supporting environment. The Web provides infrastructure for such an environment for formal specification and design because it allows sharing of various design models and provides hyper textual links among the models. Recently the Semantic Web Activity proposed the idea of having data on the web defined and linked in a way that it can be used for automation, extension and integration. The success of the Semantic Web may have profound impact on the web environment for formal specifications, especially for extending and integrating different formalisms. This paper demonstrates how RDF and DAML can be used to build a Semantic Web environment for supporting, extending and integrating various formal specification languages. Furthermore, the paper illustrates how RDF query techniques can facilitate specification comprehension.
