This paper characterises two approaches to the use of metadata for resource discovery. The first, the Heavy approach, emphasises the quality of the metadata. The second, the Light approach, emphasises obtaining the largest number of resources, using software techniques to compensate for the reduced metadata quality. The approaches are illustrated with a series of case studies: library catalogues, the web, and educational resources. In designing a system, the choice of approach will depend on the particular requirements. Light metadata approaches scale better as the number of resources in the system increases.
