Due to the many different perspectives taken when using ?information?, it has inevitably become a vague term. In the context of MMC it is defined as the outcome of ?interpretation? when applied to data. Furthermore, MMC is achieved through one of two types of information artefacts: data-based (DB) or knowledge-based (KB). Unlike KB artefacts, the DB ones have been well studied in HCI. This short paper argues that effective communication of KB information must be addressed at two levels, the level of the InfoArtefact and the level of the InfoSpace. For the latter, it is necessary to develop the concept of ?navigationable? InfoSpace. This can be achieved by fusing the semantics of KB InfoAartefacts supported by the provision of visual cues to support navigation in such environments.
