This material is organized in a special purpose distributed knowledge pool that provides all the essential management and browsing functionality to allow for the organization and dissemination of the content. In this paper we describe the design of the CHIRON knowledge pool focusing on its extensibility features. We also present its web-based user interfaces.

INTRODUCTION The CHIRON project is a Leonardo Da Vinci Project that aims to develop reference material presenting and analyzing research outcomes, experiments and best practice solutions for new forms of eLearning, based on integration of broadband web-, digital TV- and mobile technologies for ubiquitous applications in the sector of non-formal and informal life-long learning. One of the most valuable tools for its success is the knowledge pool, a web-based distributed information system that handles this reference material offering functionalities for managing, searching and browsing it. In particular, the basic elements of the knowledge pool are the following:  Data base with information of channels for data collection and continuous data sources such as scientific publications and conferences, research projects, thematic web resources, sources of statistical data, sources of technological data, international VET associations, international standardization committees, consultation bodies, task force groups and official documents of the European Commission etc.  Data base of all the possible users of the reference materials according to the defined project target groups. It will be used to disseminate regular information about the project progress as well the content of the reference materials.
