The foundation for future education, teaching, training, learning, and performing infrastructure - The open interoperability conceptual framework approach.

The proliferation of Information and Communication Technologies (ICT) in Education, Teaching, Training, Learning, and the operational application (Performing) of acquired knowledge, skills, and competencies in contemporary social environments has directly influenced the transformation of early Networked Learning (NL) concepts into a Global Learning Infrastructure. Creating cooperative/collaborative stakeholders networks composed of learning subjects, objects, and competencies consumers, exposes the significant potential for gaining overall social progress. The main challenging obstacles of such globalization are: embedding semantics into the competence credentials carriers, trusted dissemination of verifiable competence tokens, the heterogeneous ontologies mapping, and sustainable service delivery infrastructure. The mainstream motivation of our research is the specification and development of a conceptual framework that fosters the interoperability of different stakeholders, whether individual or institutional, to declare, share and maintain the representative collections of information resources related to the particular Education, Learning, Teaching, Training, and Performing (Research, Development, Production, and Service) endeavors. In this article, we have specified an open, heterogeneous, interoperable conceptual framework capable of orchestrating past, current, and future paradigms to foster building the foundations for comparative analysis and evaluation of traditional and nontraditional competency-building processes, joined with students' portfolio creation, dissemination, and management. It is a starting specification that would serve for the future: open, heterogeneous, cooperative/collaborative, service-oriented software framework specification and development.
