Most LMS systems are web-based to facilitate "anytime, anywhere" access to learning content and administration. Some widely known open source LMS are Clarolinthai eFront Dokeos OLAT and Moodle, famous commercial LMS are WebCT and Blackboard.

IMS:

The IMS Global Learning Consortium (usually known as IMS) is a non-profit standards organization concerned with establishing interoperability for learning systems and learning content and the enterprise integration of these capabilities. Their mission is to "support the adoption and use of learning technology worldwide". Some famous IMS standards are the CP (Content Package) standard used to import/export of content, the "Learning Resource Meta-data Specification" (LOM) or the QTI standard for question and test interoperability.

SCORM:

The Shareable Content Object Reference Model (SCORM) is a standard for web-based e-learning. It defines how the individual instruction elements are combined on a technical level and sets conditions for the software needed for using the content. SCORM is distributed by the Advanced Distributed Learning (ADL) Initiative, a US organization under the Department of Defense (DoD).
