Observations of metadata Observations of metadata creationcreationWhen entering metadata for a learning

object observations show that:◦Phrases rather than single words are used◦Repeated content is often used◦Very few keywords are entered if any◦The keywords used were either very

specific or very generic, rarely a mixture of both

This creates a problem for searchers of information and limits the possibility of the learning object being found within a repository
