Semantic web and Grid Computing are critical factors in the next web intelligence generation. A fundamental aspect inside this challenge is the provision of a wide disseminated platform of abstract resources that permit us to get the right information at the right time. Grid services could be understood as proper requesting resources (agents, databases, data-mining, ontologies, etc.), but also as the kind of the organization that a concise domain needs in order to offer its capabilities to other specific domains.

In this sense, the goal of getting the best distributed cooperative scenario, starting from many pre-existing Web Information Systems, is a fundamental part of this important challenge.

This paper proposes how to achieve a flexible cooperative assembly of Grid components and resources applied to a Digital Archive Semantic Integrated Architecture, we are researching since 2002.
