It is well known that selectivity leaves a lot to be desired in searching for information resources on the Internet with existing search systems[DESA4]. This has prompted a number of researchers to turn their attention to the development and implementation of models for indexing and searching information resources on the Internet. In this white paper 2 we examine briefly the results of a simple query on a number of existing search systems and then discuss two proposed index metadata structures for indexing and supporting search and discovery: the Dublin Core Elements List and the Semantic Header.
