DIMMA Work Plan

The work carried in the DIMMA project can be divided into two parts:

• The development of a programming model which extends the ANSA computational model for new types of interactions and resource management more suitable for real-time and multimedia applications. The programming model will support explicit binding ,operational and stream/signal interfaces , selective resource transparency and declarative QoS directives.

• The development of the engineering model which enables the programming model. The new engineering engine is intended to emphasize on modularity, interworking, performance, scalability (up and down), support of multiple communication stacks, support of resource separation and real-time scheduling.

• We are also developing a stub generator toolset, that enables the support of several IDLs and the generation of client and server stubs for the DIMMA supported engineering platforms (e.g ODP, CORBA). The toolset is built around the Abstract Syntax Tree concept (AST), as a syntax-free way to capture the semantics of interfaces. The stubs generated are where possible independent from the engineering details such as transport used, marshalling/unmarshalling algorithms. The AST also serves as a data interchange format between the tools and services in the DIMMA development and runtime environment (type and scope checker, interface repository, trader).
