Aims of project (i)
• To facilitate the creation, sharing and
reuse of learning objects and services:
– generic ‘engine’ architecture,
– tools for the basic specs: MD and CP
• CP&MD Player: now stable,
• Focus away from development of new
features, and on to support and
maintenance.

Aims of project (ii)
• To enhance the range of pedagogical
approaches realisable through the use
of lesson plans:
– bringing the specs to life,
– beyond describing and organising content.
•LD Editor:
–To create IMS LDs.
•LD Player:
–To visualise them

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

(metadata)
(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).

LD History
• EML (from OUNL) Abstract Description,
• Interactions, Information,
• Play as metaphor.
• IMS Learning Design describes how one or
more players takes a ROLE (learners,
teachers etc.) and performs a series of
ACTIVITIES (browsing, assessment,
discussion, simulation) in an ENVIRONMENT
(learning objects and services).

An enormous job,
This is the first IMS LD Editor,
This is its first iteration,
Other UIs can be built on top of the
current ‘engine’,
• All the IMS LD Elements with all the
valid relationships,
• All it does is write an XML file.

In practice
• LD Editor complemented by a database
for storing LD fragments,
• Few people will ever create whole
Designs from scratch,
• Templates: generic designs.
• Wizards: SLEDS, WCKER

Timetable
• Editor: Dec 2004
• Incremental releases, adding
– IMS LD Level B: properties and conditions
– Level C: notifications
– UI enhancements
• Player: Feb 2005
– Updates to mirror editor functionality
• End of funding: July 2005

– Building on RELOAD
• Internationalization, Validators, More Specs
(LIP), New User Interfaces, Application Profiles
• UNFOLD
– Bringing LD specs to a wider community:
• Developers > Implementers > End Users
