Abstract
A method for versioning learning objects comprises identifying learning content, which includes a plurality of learning objects, for storage in a content repository. Each learning object comprises or contains at least one content file. The method then includes comparing first version information of a first of the content files to versioning information obtained from an object version file identifying a prior version of the particular learning object. In response to at least a portion of the first version information of the first content file matching a corresponding portion of the versioning information stored in the object version file, a pointer to a corresponding content file in the prior version of the learning object is stored in a new object version file.
