The ARIADNE Foundation is a not-for-profit association that aims to: a) Carry out basic and applied research that will improve creation, sharing and reuse of knowledge through the use of technology; b) Develop and deploy methodologies and software that will provide flexible, effective and efficient access to large-scale knowledge bases; c) Apply the results of its research and development activities to help preserve multicultural and multilingual knowledge assets and collections; and d) Explore how these research and development results can be adopted and sustained so that they support educational and research communities. To support this goal, ARIADNE has created a standards-based technology infrastructure that allows the publication and management of digital learning resources in an open and scalable way. The vision that drives the continuous development of this infrastructure is to provide flexible, effective and efficient access to large-scale educational collections in a way that goes beyond what typical search engines provide. ARIADNE was initially set up by a network of European stakeholders, expanding now into a global network of member institutions sharing the same vision. ARIADNE is a member of the Global Learning Objects Brokering Exchange (GLOBE) Alliance and contributing towards the development of a global learning infrastructure that can be accessible from all.
