Abstract:
Metadata is structured, descriptive information about a resource. It is the
information that is gathered and recorded about a resource. For DLESE this
means providing information like a title, description, audience, geospatial
coverage, keywords, etc. about classroom activities, curriculum, scientific
visualizations, lesson plans, data, annotations, collections, images, or news
and opportunities, etc. Well-structured metadata integrated with an efficient
discovery system promotes targeted searching, browsing and use of such
resources by the Earth system science community. Once a resource is ?found? in
the library, metadata is the information about the resource that is returned to
a user. It is also the information that is exchanged with other libraries.
Metadata records are the content of DLESE. DLESE does not hold the physical
files of resources, only metadata records are held. Therefore, metadata is a
key structural component of the library. Technically, DLESE metadata is kept in
the form of structured digital records in the eXentisible Markup Language
(XML).
Since DLESE provides access to a broad spectrum of resources, different
metadata frameworks, ADN, DLESE collection, annotation, news and opportunities,
have evolved to support the unique characteristics of the resources being
described.
