Projects

• Offline CMI
• Discussed earlier this week. Final edits for
  document to be complete next week, then
  distributed.
• Bill hopes for a vote in August
• Discuss AGR in Stuttgart
• XSD for CMI Course Description
• XSD for AICC Metadata

XSD for Course Structure - Purpose

• Represent AICC Course Structure Files in one XML
  File
• Course description (.CRS) file
• Descriptor (.DES) file
• Assignable Unit (.AU) file
• Course structure (.CST) file
• Objective relationships (.ORT) file
• Prerequisites (.PRE) file
• Completion Requirements (.CMP) file
• Augment the information to use this file as the
  super manifest of a content package.

Data Model Based on SCORM 1.2
SCORM Information (Info we left out)

Course Structure Files
Completion Requirements (to complete sequencing)
Objective Relationships
Assets (to complete the manifest)

Status of XML Course Description

• Option 1 continue
• Document and presentation describing data model
  exists
• Build an XSD
• Option 2 IMS/ISO Content Packaging
• Evaluate how to use with AICC
• Document how to get all of AICC Course
  Description into a content package
• Build and XSD

7
XSD for AICC Metadata

• Status of AICC Metadata
• Approved document (June 2007)
• LOM based
• Some differences

8
AICC vs LOM
AICC Metadata is a superset of LOM
AICC
Metadata
LOM Metadata
LOM elements not used by the AICC general.covera
ge educational.semantic density educational.typi
cal age range
9
LOM Support

• All LOM elements have the same name
• All LOM elements have the same data type
• All LOM elements include the same vocabulary with
  some elements containing additional vocabulary
  tokens
• All LOM elements and vocabulary tokens have the
  same definitions (to the best of our
  understanding)
• Where ambiguous, missing or incomplete, the AICC
  attempted to expand the definitions for better
  clarity and interoperability.
• We did not attempt to change the definitions.

Future for AICC MetadataProposed June 2007

• Use guidelines provide feedback
• Refine the document
• Develop an AGR
• What should we recommend
• There are multiple use cases for this guideline
• Develop and XML binding
• Develop best practices guide
• Identify new co-lead (Bill Shook current lead)

11
Develop XML Binding Options

• LOM binding is extremely complicated
• Multiple XSD files
• Many complex data-type checking features
• IMS has developed simplified version of the
  binding
• Rob Able said that we are free to base our
  binding on the IMS binding
• He sent me a copy
• Develop our own binding

XSD Projects Summary

• Both projects have stalled out (2007)
• Both projects have an XSD component
• Jack Hyde has volunteered to build XSDs before
  the Stuttgart meeting
• Need tools an XSD tool
• Questions
• Do we need to proceed?
• Can AICC provide Jack the tools?
• Are there other volunteers/options?
