An Internet-Based Research on Digital Educational Resources Sharing
Services such as searching, transforming and sharing digital educational resources can be effectively realized through metadata. With the rapid development of internet, digital educational resources have the features of wide distribution, large amount, diverse platform and different standards. Therefore, internet users are s,pposed to switch or map the metadata of different standards or patterns, I.e. To realize a kind of metadata interoperation, the main technological methods of which are metadata switching, OAI,metadata reuse and metadata norm control, etc.However, all these methods defects in staying on a specific or abstract grammatical level. A new method,ontology-based metadata interoperation model, can take corresponding measures from semantic and grammatical perspective respectively to successfully solve the problem of interoperation on metadata semantic level.
