ACACIA in short… Objectives: Offer methodological and software support (i.e. models, methods and tools) for construction, management and diffusion of corporate memories. Corporate memory : Explicit and persistent materialization of crucial knowledge and information of an organization to ease access, sharing and reuse by the members of the organization in individual and collective tasks. = Individuals + Organization + Technology Need of a multidisciplinary approach

Past and Current work on Corporate Memories (10 minutes) Current and future work with Semantic WS (10 minutes)

Corporate semantic Web Resources: persons, documents (XML, HTML...), services, software, hardware, etc. Ontologies: describing the conceptual vocabulary shared by the organisation communities Semantic annotations: on these resources (e.g. persons skills, document contents, characteristics of services/software/hardware), using the vocabulary defined in the ontologies Diffusion on the intranet / corporate web.

Web services & Enterprise application Transversal use of enterprise modeling End of 90s: enterprise modeling for KM In the past 2 years: technology and application integration can benefit from these models too Evolution of KM scenarios Until end of 90s focus on: knowledge capture, storage, access and diffusion More and more often: computation, decision, routing, transformation Unified and integrated access to knowledge sources and corporate applications

Memories with a broaden scope Corporate memories including: information storage services; information capture services; computation and inference services; information flows management services; information mediation services; information presentation services; Resources may be internal or external external standard library, online service; interoperate smoothly and integrate workflows at the business layer.
