Supporting Learning Object Versioning
Learning objects are often stored in distributed and decentralized repositories throughout the Internet. This provides unique challenges when managing the history of such an ob-ject, as traditional versioning techniques (e.g. CVS, RCS, etc.) rely on centralized man-agement. These challenges have been largely ignored by the educational technology community, but are becoming more important as sharing of learning objects increases.
This thesis explores these issues by providing a formal version model for learning ob-jects, a set of data bindings for this model, and a prototype authoring environment which implements these bindings. In addition, the work explores the potential benefits of ver-sion control by implementing a visualization of a learning object revision tree. This visualization includes the relationship between objects and their aggregates, the struc-tural history of an object, and the semantic changes that an object has undergone.
