摘要：Since the emergence of the World Wide Web in the mid-1990s,
metadata has been recognized as a key technology for digital
libraries. Metadata is typically defined as ¡°data about other data¡± ¨C
a simple definition that embraces a broad range of resources from library
catalogues and indexes to thesauri, ratings, reviews and terms and
conditions for use. On the Internet, metadata is designed for tasks ranging
from resource description and discovery to archiving, trading, content
filtering, resource syndication and information management. This diversity
of purpose reflects the variety of information resources available on the
Internet, ranging from personal web pages to huge portals for government
information, digital libraries and shopping catalogues, as well as the variety
of users ranging from young children to businesses and professionals.
