Abstract:

Reusable information objects and reusable learning objects are the building blocks of e-learning courseware and e-documentation. A strong business case can be made for implementing a single-source content repository for RIOs/RLOs to achieve reusability between enterprise applications. Keys to achieving reusability include: an effective metatagging scheme, appropriate levels of granularity, and adherence to standards such as the SCORM.
