Why we need standards
Standards Promote:• Persistence
– Remember laser disc based materials,
• Discovery– Beyond your local community
• Sharing between different systems– For efficiency.
• Flexibility– Internationalization and Accessibility.

Who makes standards.
IMS Working Groups
specification implementation standard
User Needs
New Technology
Research
review and feedback
IEEE
CEN/ISSS
ISO
ADL SCORM
(conformance)(certification)
© RELOAD 2003, funded by
What do they cover?
• Metadata
• Content Packaging
• Simple Sequencing
• Learning Design
• Question and Test Interoperability
• Digital Repositories
• Enterprise
• Accessibility
• Learner Information Profile
• Competency (and Portfolios)
• (Interactive Content)
© RELOAD 2003, funded by
Specification Documents
• Each Spec. has 3 components:– Information Binding
• XML Binding – how to describe.
– Information Model• What to describe: definitions, rules and
constraints
– Best Practice Guide• Guidelines for using and implementing.
• Available from IMS web site for free

(how the content is organised)
(what resources are needed)

Why do we need tools?
• Avoid working directly with XML(files get much more complicated than
the one in our example),
• speed up xml creation.• reduce errors,• aid conformance (and uptake),

RELOAD Tools
• Reference Implementation– Test, benchmark
• Visually assemble and manipulate Content Packages– Better than XML
• View Content Packages– For testing and preview.

Future
• RELOAD 1.1.1+ stable and feature complete
• Open Source – others are encouraged to extend, and are doing so
• Designed to adapt easily if specifications are revised.
© RELOAD 2003, funded by
Creating CPs with RELOAD
• 10 minute demo• Hands On• Further Tasks• Round-up
© RELOAD 2003, funded by
Hands On: A First CP
• Core Tasks (p7: Collect Resources Together -p16)– Collect Content– Create Working Directory– Prepare Placeholders– Import Content– Make Organizations– Preview– Rearrange– Add Metadata– Package and Zip
© RELOAD 2003, funded by
Advanced tasks
• Advanced Tasks (p23-25)– Manifests– Dependencies
© RELOAD 2003, funded by
Roundup
• RELOAD allows us to move from Abstract to Physical– Tests (proves) the specification– Links Content Creation and Content
Sharing
© RELOAD 2003, funded by
3. Metadata
• Describes resources:– General (title and keywords)– Lifecycle (versioning)– Metametadata (who wrote the record)– Technical (assisting implementation)– Educational (level)– Rights (copyright and other restrictions)– Relation (to other content)– Annotation (usage metadata)– Classification (in a system)
© RELOAD 2003, funded by
Why metadata is important
• Discovering Resources– Description, educational MD
• Using Resources– Version control, technical
• Enforcing Rights• Attributing Ownership/Authorship
© RELOAD 2003, funded by
Application Profiles
• Metadata must be interoperable– ~80 elements in LOM– Decide on important elements at a
local (organisational) level– Use shared vocabulary/taxonomy
• Kinetics, motion, physics …
– Implement Rules and restrictions
© RELOAD 2003, funded by
Good Metadata
• Added by Information Professionals• Consistent across a repository• Assists Reuse
– Usage metadata – recommendation systems like Amazon:
© RELOAD 2003, funded by
Hands On Session
• Take your own content and create content packages.
• Add Metadata– http://www.cetis.ac.uk/profiles/
uklomcore
• If you don’t have any content of your own, get some here. – http://reload.ac.uk/ex/
• Aggregate Packages.
© RELOAD 2003, funded by
Roundup
• You should have been able to :– Make your content reusable– Describe your content– Aggregate your content with others.

Where next?
• A repository– JORUM – Merlot , SMETE
• Federated Search:
– Maricopa Learning Exchange – CAREO
• An LMS– WebCT, BlackBoard, Saba, Teknical

4 SCORM
• SCORM: The Shareable Content Object Reference Model
• SCORM is real, – Certification (soon),– Now (almost).
© RELOAD 2003, funded by
SCORM History
• US Dept. of Defense, Boeing (AICC)• Training• Single User Model
• Drives (pulls) specs forward.
© RELOAD 2003, funded by
SCORM Future
• Close harmonisation with equivalent IMS specs – avoiding divergence.
• Incorporating Simple Sequencing (1.3 –2004)
• Question and Test Interoperability (1.4)
• Simulations and adaptive learning (v2)
© RELOAD 2003, funded by
Hands On Session
• In addition to CP and MD, SCORM includes support for management of learning (p20 SCORM Elements -22):– Pre-requisites– Max time allowed– Time Limit Action– Data from LMS– Mastery Score
© RELOAD 2003, funded by
SCORM Player
• Allows SCORM functionality preview without using an LMS.– Simple to set up– See what the learner sees– Test functionality.
– SingleCourseEx.zip

The Future
• RELOAD Editor is stable• Others are developing functionality
– SCORM 1.3 editor (ADL)– ALOHA Metadata Editor (CanCore)– VDEX Editor (ICBL)
• Learning Design

Roundup
• RELOAD is about enabling– Engage with the standards– Test the standards– Improve the tools.
