Abstract

This paper describes emerging metadata practice and standards. It gives an overview of the environments in which metatdata is used, before focusing on metadata for information resources. It outlines an approximate typology of approaches and explores different strands of metadata activity. It discusses trends in format development, metadata management, and use of search and retrieve protocols. It concludes by discussing some features of future deploament of metadata in support of network resource discovery

Abstract

Examines metadata within the context of network information management. Defines metadata, gives an overview of resource discovery service model in the context of the Web, and gives a simple typology of resource discovery metadata and the associated characteristics of metadata formats. Describes some of the projects and services, which are now using metadata for resource discovery in a networked environment. Covers: the Dublin Core, Web indexes, projects and services using metadata, associated technologies, and use of identifiers

Abstract

The Semantic Web activity is a W3C project whose goal is to enable a 'cooperative' Web where machines and humans can exchange electronic content that has clear-cut, unambiguous meaning. This vision is based on the automated sharing of metadata terms across Web applications. The declaration of schemas in metadata registries advance this vision by providing a common approach for the discovery, understanding, and exchange of semantics. However, many of the issues regarding registries are not clear, and ideas vary regarding their scope and purpose. Additionally, registry issues are often difficult to describe and comprehend without a working example. This article will explore the role of metadata registries and will describe three prototypes, written by the Dublin Core Metadata Initiative. The article will outline how the prototypes are being used to demonstrate and evaluate application scope, functional requirements, and technology solutions for metadata registries. Metadata schema registries are, in effect, databases of schemas that can trace an historical line back to shared data dictionaries and the registration process encouraged by the ISO/IEC 11179 community. New impetus for the development of registries has come with the development activities surrounding creation of the Semantic Web. The motivation for establishing registries arises from domain and standardization communities, and from the knowledge management community. Examples of current registry activity include:

Abstract

The Renardus project has brought together gateways that are 'large-scale national initiatives'. Within the European context this immediately introduces a diversity of organisations, as responsibility for national gateway initiatives is located differently, for example, in national libraries, national agencies with responsibility for educational technology infrastructure, and within universities or consortia of universities. Within the project, gateways are in some cases represented directly by their own personnel, in some cases by other departments or research centres, but not always by the people responsible for providing the gateway service. For example, the UK Resource Discovery Network (RDN) is represented in the project by UKOLN (formerly part of the Resource Discovery Network Centre) and the Institute of Learning and Research Technology (ILRT), University of Bristol -- an RDN 'hub' service provider -- who are primarily responsible for dissemination. Since the start of the project there have been changes within the organisational structures providing gateways and within the service ambitions of gateways themselves. Such lack of stability is inherent within the Internet service environment, and this presents challenges to Renardus activity that has to be planned for a three-year period. For example, within the gateway's funding environment there is now an exploration of 'subject portals' offering more extended services than gateways. There is also potential commercial interest for including gateways as a value-added component to existing commercial services, and new offerings from possible competitors such as Google's Web Directory and country based services. This short update on the Renardus project intends to inform the reader of progress within the project and to give some wider context to its main themes by locating the project within the broader arena of digital library activity. There are twelve partners in the project from Denmark, Finland, France, Germany, the Netherlands and Sweden, as well as the UK. In particular we will focus on the specific activity in which UKOLN is involved: the architectural design, the specification of functional requirements, reaching consensus on a collaborative business model, etc. We will also consider issues of metadata management where all partners have interests. We will highlight implementation issues that connect to areas of debate elsewhere. In particular we see connections with activity related to establishing architectural models for digital library services, connections to the services that may emerge from metadata sharing using the Open Archives Initiative metadata sharing protocol, and links with work elsewhere on navigation of digital information spaces by means of controlled vocabularies.
