The Share.TEC system has the main goal to establish a highly visible and functional portal with advanced brokerage services that will provide personalised access to a wide-range of Teacher Education (TE) content. The heart of the Share.TEC system is the central repository, storing metadata about TE resources. In this paper we describe the design of the digital Share.TEC repository, providing the more flexible and powerful ways for representing Common Metadata Model (CMM) metadata records and objects from the Teacher Education Ontology (TEO), and ensuring the most efficient and comprehensive search and reasoning abilities, as the key factors for the success of the Share.TEC project. We describe the data models for representing CMM and TEO, as well as the processes ensuring their correct coexistence.

This paper presents the Share.TEC system architecture and the first system prototype. This description stresses on the main system components and underlying technologies, standards and protocols. The main system functionalities are following logically from the main use cases and user requirements. The system design allows a tight integration between data, which have been automatically harvested from various external repositories, and a representation of the ontology that describes all aspects of the teacher education domain. The proposed implementation relies on modern features such as searching a net of digital objects interconnected by custom-defined relations. A multicultural system which accommodates to the user preferences requires specific user interface. The dynamic approach for presenting the information to the user, based on the teacher education ontology, contributes to the flexibility of the system.
