What Systems are Needed for LD?

• Will look at this in two parts
• The Authoring Environment
• The Runtime Environment
• Based on
• The Valkenburg Diagram
• The Dagstuhl Diagram
• The LADIE Reference Model elaboration

Run Time Environment

• Easier to think of it in two parts
• Setting up a Unit of Learning for a Run
• the Set up Architecture
• Using a Run live with Learners
• the Runtime Architecture

Set Up Required Interfaces

• LD Unit of Learning Repository
• Store, Search and Retrieve LD Units of Learning
• Person
• Get Users and Groups
• Load Learner Properties
• Learning Services
• Set up (dedicated) Service instance (with users
  in role)
• LD Runtime Player
• Initialise Unit of Learning
• with users in roles service handles
  property values default values
• Start Run
