XAROP: A Midterm Report in Introducing a Decentralized Semantics-Based Knowledge Sharing Application

Knowledge management solutions relying on central repositories sometimes have not met expectations, since users often create knowledge ad-hoc using their individual vocabulary and using their own individual IT infrastructure (e.g., their laptop). To improve knowledge management for such decentralized and individualized knowledge work, it is necessary to, first, provide a corresponding decentralized IT infrastructure and to, second, deal with specific problems such as security and semantic heterogeneity. In this paper, we describe the technical peerto-peer platform that we have built and summarize some of our experiences applying the platform in case study for coopetitioning organizations in the tourism
