In this project deliverable present the idea of Conceptual Data Structures (CDS), a unifying data model for end-user semantic personal knowledge management. We present concepts as well as a software framework.
We describe two main user interface prototypes based on the CDS framework and their evaluations. First, the NEPOMUK hypertext knowledge workbench (HKW) is described. Second we describe the visual knowledge workbench (VKW), consisting of two parts: iMapping and QuiKey. iMapping is graphical UI concept for personal knowledge mapping, QuiKey is a ``visual command line for knowledge articulation and querying and browsing. All prototypes are based on the same CDS API and are hence interoperable. The CDS API is integrated with the NEPOMUK RDF repository. We describe the current and planned integration status.
Additionally, we describe some natural language processing tools and a WikiModel parser framework developed in our workpackage and how they integrate with CDS.
