| Summary: | 碩士 === 輔仁大學 === 圖書資訊學系 === 86 === Electronic resources in the networked environment present
different characteristics from library''s traditional collection.
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.
