This work presents a proposal for building corporate memory architecture. It has three layers: sources, middleware and repositories. First, we create an conceptual enterprise model, named Organizational Baseline (OB), based on theories of business management and organized in accordance with an approach of ontology. Second, we use multi agents system as a means to organize our proposal of architecture. The OB is the main component, where we store whole relevant information for the organization; it can be extracted from legacy systems, databases, Internet sites or human beings. The conceptual enterprise model is based on constructs elicited from positioning and emphasizing efficiency views of strategic analysis, together with function analysis and total quality management.
