Content management framework
When we develop an object, it must be stored, tracked, used, kept up to date and so on. One of the
most important considerations in doing this well is the type of framework, or data structure to
which each object is attached. The framework should put every object into a logical context that
aids later finding and using it.
Object-to-object perspective
At minimum the framework should allow users to establish and display objects in relation to each
other and their prerequisites. This is tantamount to a learning objectives hierarchy.
An advantage of the object hierarchy is the ability to establish prerequisite links (enabling
objectives). If an object retrieved by a learner has a subordinate, the subordinate could appear
as a prerequisite.

Object-to-process perspective
The framework display should also show how an object is connected to the other components in the
instructional design process: tasks or outcomes, test questions, assignment to lessons.
|
 |
By allowing links between outcomes and object(ives), and objectives
to lessons, we are reflecting a performance-based instructional design process. This means that
with additional features, the content management system becomes an facilitator of the instructional
design process.
The pathways established with this perspective provide a means to retrieve learning objects from an
outcome (or work centered) context. This is the key to a multiple purpose database objects. On one
hand, objects can be assembled to reflect course or lesson structure. On the other, objects can be
found to support work at hand, as in an Electronic Performance Support System (EPSS). The
connection with test questions opens a broad range of exam generation options.
User-defined links
The object management system should also be extensible, allowing users to create links to allow
custom query paths.
|
 |
With the ability to extend links in the framework, the ability
to find an object is greatly enhanced. For example, with the above pathways, we can find the object
from a task perspective or from the perspective of Product XYZ. With appropriate filters, we could
also find all objects associated with tasks that are applicable to product XYZ.

Impact of perspectives on learning object
properties
Let’s take another look at the learning object properties. If the object management system can
show the various perspectives, then the corresponding links become additional properties to every
learning object.

Additional features required
The system will need an array of user interface features such as:
- Quick and easy navigation among the objects
- Easy moving, copying, sharing of objects.
- Ability to track use of shared objects
- Security to prevent loss of control on modification of objects
- Change impact features
- Features that help prevent inappropriately linked or missing objects
|
Technically, all of these features extend the properties of the learning object.
