eLearning courses are normally composed of learning objects. The reason for this composition is the necessity to reuse the objects in di erent courses, thus reducing the e ort needed to create them. To faciliate reuse, the learning objects have to be published to learning object repositories and need to be ndable by search engines. A search engine that is limited to textual content won't deliver adequate results because the objects frequently contain multimedia information.
This problem may be alleviated by the employment of metadata, to enable the indexation of the multimedia content for the search engine.
The potentialities of the semantic web are examined in this thesis to further improve the searching. Under this aspect the available standards for metadate and learning object repositories and refaratories are reevaluated. In the applicatory part of this thesis the prototype of a search engine is implemented. The engine operates with the means of the semantic web on the data which had been gathered via OAI-PMH from learning object repostiories.
