The effective management of learning information is crucial for e-learning systems in the digitally networked age. E-learning, an emerging new approach to learning enables learners to access sufficient learning information in different systems. Thus, an increasingly important as well as problematic issue is to achieve the exchangeability and interoperability of information. This paper introduces an effective method and information model for managing learning information via standard metadata, and then proposes an Open Education Service Architecture to achieve the interoperability between heterogeneous learning systems. To better illustrate this architecture, we provide a standard compliant Learning Contents Management System to organize and classify the learning information in an e-learning system.
