We aim to provide to each SME and the ecosystem with knowledge management mechanisms to support their needs for information, service findings and recommendations. We present the design and implementation of a platform that supports the knowledge management needs in this environment. We describe the business related knowledge managed by the knowledge base (KB), as well as the architectural components and the core services supported by the KB infrastructure. Since the SMEs are independent and their KB contents are evolving we adopted a P2P framework for the cooperation of SMEs. We present the P2P framework and we outline the knowledge discovery and replication mechanisms supported by the implementation. The knowledge management mechanisms described in this paper form the infrastructure for knowledge management of the Digital Business Ecosystem IP project of EU.http://creativecommons.org/licenses/by/4.0/196-202Inaugural IEEE-IES Digital EcoSystems and Technologies Conference Christodoulakis Stavros Χριστοδουλακης Σταυρος Pappas Nikos Παππας Νικολαος Kazasis Fotis Καζασης Φωτης Anestis Georgios Ανεστης Γεωργιος Gioldasis Nektarios Γιολδασης Νεκταριος Institute of Electrical and Electronics Engineers Digital business ecosystem
