Search engines and subject catalog operate on limited description, and are less effective for discovery. Libraries have taken some approaches to organize electronic resource on Internet, such as modifying MARC formats, using classifica-tion schemes, and subject heading systems. Another modern approach is using metadata to describe and to organize networked resource. Metadata contains a set of data elements to describe the content and location of an information object and to facilitate its discovery and retrieval in the networked environment. In this research, we use literature review to analyze the status of organizing electronic resources, and we also use comparative method to describe CIMI, EAD and TEI, and to compare their control agency, scheme history, user community, subject field, system architecture, element, markup language, flexibility and extensibility, fullness, compatibility, rules for formulation of content, ease of creation, subject analysis, authorize control, protocol, implement, and future development. Our analysis shows that search engines currently used are insufficient to organize electronic resources on Internet. Information communities should develop metadata to meet diverse requirements of the different subjects, values of resources, and the different environment of uses. We make the following two suggestions: (i) the description level of metadata should depend on values of resources, (ii) the metadata should use Z39.50 as protocol and use SGML as encoding standard to improve interoperability.
