SIMBAD is a structuring research project
of the
Institut Telecom.
We are part of the Computer Science Department
of
Técom SudParis
one establishment for higher education and research
in the field of Information and Communication Technology of the
Institut Técom
We are also part of the CNRS research laboratory
SAMOVAR.
The SIMBAD project has been started in january 2004. SIMBAD mainly addresses
the complex manipulations of resources and services in a dynamic and large scale
distributed system. These manipulations include searching, classifying, indexing,
reusing and composing. We are considering dynamic systems where nodes may arrive
or quit the system at any time. Our approach does not suppose that all nodes are
strongly coupled (e.g we do not suppose the existence of a common global schema).
For the moment we are working separatly for resources (data described by
metadata) and services (programs described by interfaces). Two main applications
are addressed; e-learning environment and sharing of pedagogical resources
(so-called learning objects); virtual entreprises (dynamic interconnection of
information systems described by services and workflows).
To fulfill these objectives, our general idea is to add semantic information
to describe resources and services. These semantic informations are then used by
the different manipulation processes. Ontologies are used to define a common
referential to define semantic informations. The final goal of this project is
to work on unifying our work on resources and services in a more generic approach.
SIMBAD is structured into three main components: metadata for learning objects and
adaptation, virtual entreprises, semantic P2P systems.
