KP-LAB Knowledge Practices Laboratory -- Specification of the SWKM Architecture (V1.0) and Core Services

The objective of WP5 is to develop a generic middleware supporting knowledge management services for ‘trialogical’ learning applications. More precisely, the KPLab Semantic Web Knowledge Middleware (SWKM) aims to facilitate knowledge creation processes by supporting advanced interactions of collaborating learners (or workers) with knowledge artefacts (i.e. discovery, access, evolution, recommendation and mining). In this deliverable we present the high-level functionality of SWKM along with the Service-Oriented Software Architecture of the prototype system that will be developed by M12 (V 1.0) and the subsequent phases of the project. The proposed architecture broadly distinguishes three generic modules of the SWKM, i.e. the Knowledge Repository – responsible for the provision of scalable persistence services for large volumes of knowledge artefacts’ descriptions and ontologies; the Knowledge Mediator – responsible for the provision of services handling the main registry, discovery and evolution for KP-Lab knowledge artefacts; and the Knowledge Matchmaker – responsible for the provision of services that support interactions of KP-Lab users with knowledge artefacts employing their semantic descriptions. The services corresponding to each one of these modules are described along with the proposed functionality for each one, based upon the motivating scenarios and the subsequent definition of the key concepts of Trialogical Learning.
