| Abstract: | This paper recognizes some emerging issues on metadata as
a mechanism of resource discovery and its impact on precision of search results
in a distributed network environment. It aims to present a brief account of the
major metadata initiatives taken during the last couple of years, thus provide
glimpses of recent activities on metadata across the globe. It also highlights
a consistent growth of multiple metadata standards to meet the variety of needs
in a hierarchy of complexity. The paper examines various metadata-harvesting
tools and related technologies that fulfill the task implicit in a user’s
search. Discussion brings out some popular standards, useful protocols, and
open-source harvesters along with their intrinsic capabilities for harvesting
and presenting metadata. It also emphasizes on a variety of metadata services
viz., OCLC’s metalogue service, UKOLN metadata editor service, OAIster
harvester service, DP9 gateway service, etc. that are predominantly used in
different metadata communities. Attempt has been made to explore the underlying
principles of metadata-harvesting in DSpace and web search engines. It also
seems imperative to make a discussion on the use of multiple metadata formats
in DSpace enabled archives for exposing domain-specific metadata; and
subsequently evaluates the inherent mechanism for extensibility and
interoperability functions. Thus it proposes various means of creating metadata
in order to pursue high-precision document retrieval in dynamic collections.
Finally it notices semantic web technologies that could bring a reasonable
solution towards the integrated use of specialized metadata for long-term
management and preservation of digital objects. |
