Weaving of Software Components

One of the challenges for software components is to build new models and platforms to allow large scale interoperability of components for designing complex distributed applications. Actually, some models exist: Enterprise Java Beans by Sun Microsystems, .Net by Microsoft and the CORBA Component Model in the CORBA3 OMG standard [96] . These models and platforms are clearly not satisfactory because of the lack of functional completeness and interoperability. Moreover, the industrial propositions only deal with a lot of technical problems to capture the component software notion, but mainly forget the needs to manipulate the models of components and applications independently of the technical aspects. This point has been recently tackled by OMG with its Model Driven Architecture (MDA) initiative [94] , [101] . We agree that these points (Component Models, Component oriented Platforms and Model Driven Engineering) lead to new research problems in the goal to produce a better integrated product line from analysis to exploitation for component based applications.

Jacquard members have a great research experience in two computer science domains related with the goal of the project: Jean-Marc Geib, Philippe Merle and Raphaël Marvie have some important contributions in the Distributed Object based Platforms area [71] , Laurence Duchien, Bernard Carré and Olivier Caron on specifications and use of separation of concerns for complex applications. For example, we can quote the contributions to the OMG standardization work with the CorbaScript language [89] (proposed to the Scripting Language for CORBA RFP, and accepted as the CORBA Scripting Language chapter of CORBA3 [83] ) and with the CCM (CORBA Component Model) chapter for which we lead the response group and the revision task force. Other examples are the JAC (Java Aspect Component) platform, one of the leading platforms for dynamic weaving of aspects [97] , [99] , [100] , and the View Approach for structuring the design of information systems [110] .

We aim to associate these experiences to design and produce an ambitious new platform for component based complex applications with new methodological and technical traits for structuring the large set of hardly related problems in supporting theses applications. Models, platforms and applications have to benefit from new open middleware using separation of concerns and weaving. Our contributions want to understand how a better structure of models and platforms can give better software for complex applications.

For the next four years, the project's goals are:
