The traditional use of large search engines for retrieving educational information on the Internet is rather inaccurate and provides irrelevant search results in most cases. Recently metadata are widely used to semantically describe educational resources and a number of educational metadata specifications have been proposed aiming at defining the set of elements that can better describe an educational resource. This paper proposes an architecture for an educational metadata management system, which facilitates both metadata storage and data retrieval, by using a deductive object-oriented database. The proposed system provides not only tolls for creation, validation and modification of educational metadata documents, but also an efficient information retrieval mechanism based on user queries.
