Currently

• The only defined organization type is acyclic
  graph (tree)
• But other types are possible
• The only defined resource type is web content
• But other types are possible
• The only defined binding is XML
• Extensibility placeholders in all elements

Dereferencing Mapping
An organization element is a structured map of
resources. The resources element an
unstructured collection of resource descriptors.
An item in an organization may reference either
a resource descriptor, or a sub-manifest. In
the IMS Simple Sequencing and SCORM profiles of
IMS CP, only leaf items may reference a resource
or sub-manifest.

Resource

• Actually a digital descriptor for a resource
• In current version, resource is always web
  content
• Has an identifier (scope manifest)
• May have its own metadata
• Resource element contains an inventory of files
  and/or dependency references to other resources
• Launchable resources have an attribute whose
  value is a URL
• URL is typically relative to package root
• URL may be fully qualified external resource
• URL may have parameters
• Not launchable resources are typically used for
  shared assets

Erratum

The summary diagram in the IMS CP Information
Model document is incomplete. An item may in fact
also have meta-data

Profiles of IMS CP Simple Sequencing SCORM
Simple Sequencing adds rules to Organization and
items. Each item represents an activity. SCORM
1.2 adds some presentation data options and
specifies mandatory elements when metadata is
present. SCORM 2004 builds on SCORM 1.2 and adds
Simple Sequencing
