Common standards in learning technology will have a profound impact on the relationships among educators, learners, institutions, venders and publishers. Standards help to ensure Reusability、Accessibility、Durability、Interoperability、Adaptability、Affordability and Manageability will protect e-Learning investment. The SCORM of ADL (Advanced Distributed Learning) provides a foundational reference model upon which anyone can develop models of learning content and delivery. It is widely accepted as a major specification for the development of interoperable content and systems. The SCORM is built upon the work of the AICC, IMS, IEEE, and others to create one unified ""reference model"" of interrelated technical specifications and guidelines designed to meet DoD's high-level requirements for Web-based learning content. The current SCORM is a collection of specifications, includes the "Content Structure" and" CMI (Computer-Managed Instruction) Specification" from AICC, "Meta-data Dictionary" from IEEE, "Content Packaging" and "Metadata XML Binding and Best Practice" from IMS. The future of LT standards would depend on the development of advanced information technology, business models and content creation.
