BDL (Behavioural Description Language)

Organisation: IRISA / INRIA Rennes (FRANCE)

Functionality: Implementation of BDL operational semantics

Tools used: OPEN/CAESAR

Period: 1999

Description: Object-oriented methodologies like UML (Unified Modeling Language) are increasingly used for the design and development of distributed systems. BDL (Behavioural Description Language) [Talpin-et-al-98] is a view of UML enriched with behavioural description facilities. BDL has a formal semantics that is suitable for simulation, verification, and code generation from object-oriented specifications.

A BDL specification is a collection of classes connected via various relations, each class being represented as a directed graph whose nodes are (valued) events. BDL classes and communications can be interpreted in a synchronous or asynchronous way. Starting from a denotational semantics of BDL, four different operational semantics of BDL have been developed: synchronous small-step, synchronous large-step, asynchronous, and synchronous-asynchronous. These semantics have been implemented using the OPEN/CAESAR generic environment for on-the-fly verification of CADP.

Conclusions: The connection of BDL to OPEN/CAESAR allows to benefit from all the simulation, verification, and test generation facilities already implemented using OPEN/CAESAR. Moreover, work is ongoing to build a front-end for UML enriched with BDL is under development, by extending the tool UMLAUT [Jezequel-Pennaneac-97] for analysing and transforming UML programs.
