In this paper, we describe a knowledge management framework that addresses the needs of multimedia analysis projects and provides a basis for information retrieval systems. The framework uses
technologies to provide a shared knowledge environment, and active
, wrapping multimedia processing tools, to exploit and/or export knowledge to this environment. This framework is able to handle a wide range of use cases, from an
for researchers to end-user
. As an illustration of how the proposed framework can be used, we present a case study of music analysis.
