•Be able to discover more teaching resources
Requirement: Build the discovery of teaching resources information across different schools and other academic communities.
Scenario: Using dissimilar data descriptions and data representation results in the difficulty of sharing teaching resources among schools. The standard formats should support the discovery of relevant teaching resources among communities easier. However, it does not need the centralized data center. In other words, teaching re- sources should be collected in local sites of each school, but their metadata sets are only harvested by each site.
