dc.description.abstract | Metadata is an increasingly central tool in the current web environment, enabling large-scale, distributed management of resources. Recent years has seen a growth in interaction between previously relatively isolated metadata communities, driven by a need for cross-domain collaboration
and exchange. However, metadata standards have not been able to meet the needs of interoperability between independent standardization communities. For this reason the notion of metadata
harmonization, defined as interoperability of combinations of metadata specifications, has risen
as a core issue for the future of web-based metadata.
This thesis presents a solution-oriented analysis of current issues in metadata harmonization. A
set of widely used metadata specifications in the domains of learning technology, libraries and
the general web environment have been chosen as targets for the analysis, with a special focus on
Dublin Core, IEEE LOM and RDF. Through active participation in several metadata standardization communities, a body of knowledge of harmonization issues has been developed.
The thesis presents an analytical framework of concepts and principles for understanding the
issues arising when interfacing multiple standardization communities. The analytical framework
focuses on a set of important patterns in metadata specifications and their respective contribution
to harmonization issues:
Metadata syntaxes as a tool for metadata exchange. Syntaxes are shown to be of secondary importance in harmonization.
Metadata semantics as a cornerstone for interoperability. This thesis argues that the
incongruences in the interpretation of metadata descriptions play a significant role in harmonization.
Abstract models for metadata as a tool for designing metadata standards. It is shown how
such models are pivotal in the understanding of harmonization problems.
Vocabularies as carriers of meaning in metadata. The thesis shows how portable vocabularies can carry semantics from one standard to another, enabling harmonization.
Application profiles as a method for combining metadata standards. While application
profiles have been put forward as a powerful tool for interoperability, the thesis concludes that they have only a marginal role to play in harmonization.
The analytical framework is used to analyze and compare seven metadata specifications, and a
concrete set of harmonization issues is presented. These issues are used as a basis for a metadata
harmonization framework where a multitude of metadata specifications with different characteristics can coexist. The thesis concludes that the Resource Description Framework (RDF) is the
only existing specification that has the right characteristics to serve as a practical basis for such a
harmonization framework, and therefore must be taken into account when designing metadata
specifications. Based on the harmonization framework, a best practice for metadata standardiza-
tion development is developed, and a roadmap for harmonization improvements of the analyzed
standards is presented. | en_US |
