Modern life is hard to imagine without Internet and the myriad of information it offers. That’s why it is becoming increasingly important to sort out this information and develop methods for quick and ”intelligent” searching. These are problems for the Semantic Web [1, 2]. It provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. Currently there are lots of tools and standards available for metadata handling. In the following paper I am describing a design for managing XML content exclusively on the database side. As a case study, I explore the capabilities of MySQL 5.1 in a user friendly Service Provider environment which collects metadata from different online repositories. It stores the information in a centralized database thus making it available for local applications and at the same time providing basis for optimized searching through one of the latest database technologies. In addition, I offer a solution for conversion between metadata formats, e.g. metadata standardization.
