The work builds on the results of three successful IST projects under the European Commission's 5th Framework Programme (CELEBRATE, ITCOLE and VALNET). It is designed to help strengthen the integration of the European Commission's Information Society Technologies Programme's (ICT) research effort in an enlarged Europe. The large-scale project involving seventeen partners, six of which are Middle and East European states (MoEs) from new member states, will:

• Develop and ensure take-up of an open source technical architecture to support content exchange/collaboration between MoEs and other owners of educational repositories.
• Develop and ensure take-up of an open source learning toolbox that supports the collaborative use of learning resources by providing an environment for group centered work and knowledge building activities, but which also provides the sort of course-building tools found in more conventional Learning Content Management Systems.
• Research and testing of new approaches that can improve semantic interoperability related to the discovery and evaluation of learning resources.
• Validate CALIBRATE project results in up to 100 schools using an advanced validation methodology.

CALIBRATE will also link to a number of other EUN (European Schoolnet) projects and initiatives that will build a wider framework and lay the foundations for the implementation of a new European Learning Resource Exchange (LRE). This will be accessible to all interested Ministries of Education participating in the EUN and other public and private sector owners of educational content repositories.
