The WP5 glossary defines 'knowledge management' as follows:
"Knowledge management: intends to identify, represent, codify and use various types and forms of knowledge residing in workers or groups within an organization."
As far as I understand the main difference between these definitions is due to differences in the understanding of the concept of knowledge. While the latter definition implies a rather objectivist view on knowledge, the former definition emphasises the situated nature of knowledge.
