DEFINITIONS OF E-LEARNING OBJECTS
E-Learning Objects– Digital and efficient
– Self-standing, discrete, meets an instructional objective
– Reusable and sharable

THE VALUE OF METADATA
The vision of metadata is:– just the right content, to– just the right person, at– just the right time, on– just the right device, in– just the right context, and – just the right way.

METADATA
GENERATION

DEVELOPING A METADATA STATEGY
How much ……– Can be automatically generated?– Can be automatically harvested from another
repository or discovered from the learning object itself?– Must be human-created?
For use by ……– An end user– A metadata creator or manager– A computer application or program

THE VALUE OF SCORMSCORM (Sharable Content Object Reference
Model)– A suite of technical standards that enable web-based learning
systems to find, import, share, reuse, and export learning content in a standardized way
– Built on AICC, IMS, IEEE, ARIADNE, Dublin Core primarily for vendors and toolmakers who build Learning Management Systems (LMS) and learning content authoring tools
– Specifications include metadata, XML binding for metadata tags, content packaging (XML “manifest” that defines all the contents and their relationship to one another for the LMS)
.

THE VALUE OF SCORM
SCORM goals include a run time environment (API and data model) that enables standardized:– Tracking of learners– Assessment of skill and competency mastery by all
SCORM compliant LMS’s– Remediation and other types of complex directed
learning experiences and behaviors
MUCH WORK IS STILL NEEDED….

THE VALUE OF MPEG-7
– Multimedia Description Interface – the metadata specification for multimedia
– MPEG-7 is not just a better implementation of MPEG-1, 2, or 4 (MPEG-3 is no longer used, MPEG-5 and 6 have never been used, but there is an MPEG-21 (DRM))
– Semantic interoperability

METADATA CROSSWALKING, ABSTRACTIONS AND WEB
SERVICES
Addressing different communities:– Digital libraries and repositories (NSDL
uses Dublin Core metadata)
– Educational technologies and LMS’s (WebCt and CourseInfo are SCORM compliant)
– Portals (web syndication systems)
