Previous research on corporate household and corporate householding has presented examples, literature review, and working definitions. In this paper, we first improve our understanding of the area by developing a typology of corporate householding tasks and knowledge requirements. We stress the importance of "context" for use to get the appropriate answer for each task. Then we propose an approach to handle these tasks using Communities of Practice (COP) for knowledge acquisition and extensions to the COntext INterchange (COIN) technology for knowledge storage and knowledge processing
