Learning Management System (LMS)

A comprehensive ALPS (Application-Level Profile Semantics) profile that defines the complete semantic vocabulary and interaction model for an enterprise-grade Learning Management System. This specification covers all aspects of online education including user management (students, instructors, administrators), course creation and delivery, content management, assessments, grading, communication tools, collaboration features, analytics, and accessibility. The profile is organized into semantic descriptors, state transitions, and navigation patterns to support standardized implementation and interoperability across educational technology platforms.

 <title>Learning Management System (LMS)</title>    
 <doc>A comprehensive ALPS (Application-Level Profile Semantics) profile that defines the complete semantic vocabulary and interaction model for an enterprise-grade Learning Management System. This specification covers all aspects of online education including user management (students, instructors, administrators), course creation and delivery, content management, assessments, grading, communication tools, collaboration features, analytics, and accessibility. The profile is organized into semantic descriptors, state transitions, and navigation patterns to support standardized implementation and interoperability across educational technology platforms.</doc>
