UTILIZATION OF METADATA FOR QUALITY ASSURANCE IN THE INTERNATIONAL SHARING AND REUSE OF OPEN EDUCATIONAL RESOURCES Open Access

In order to sustain the development and utilization of learning content under the limited financial and human resources, the sharing and reuse of open educational resources (OERs) have been promoted in various school levels and disciplines. In many countries, central organization(s) collect both learning content and its metadata, and provide them to learners and teachers with distinctive value‐added services from their portals. Collaborations among the national portals have also emerged beyond borders.Global Learning Object Brokered Exchange (GLOBE) is an international consortium of the hub organizations, which manage a federated repository and/or a meta‐referatory in each country and region. GLOBE was established in September 2004 by five founding members, and now twelve organizations in the world participate in. By adopting IEEE LOM version 1.0 for the metadata standards, SQI for the query language, and OAI‐PMH for harvesting, GLOBE realized a global search and delivery infrastructure for lifelong learning (LLL). At present, while the repositories all over the world store huge number of learning content and metadata, the variance of the quality becomes much bigger. In addition, because the effectiveness of learning content is relative and dependent on contextual factors, both optimizations specialized in learner characteristics and localizations to each language/culture are indispensable. The users need some supports on the quality and pedagogical guidance when they find their right content. GLOBE, based on multilingualism, multiculturalism and pluralism, collaborates to build up standardized services on the quality assurance of the content utilizing the “Educational” items of LOM. In AAOU framework also, the organizations can promote “openness”, and share the quality learning content and educational information by using a standardized content search and delivery infrastructure.
