- Abstract
- The relationship between library catalogues and electronic resources differs from that between catalogues and physical materials, particularly with regard to cataloguing rules, which were originally designed to help users of card catalogues to find physical works on library shelves. However, these rules apply awkwardly to electronic resources because functionally different electronic works raise special cataloguinf issues. Discusses the problems of describing remote electronic resources in online catalogues with particular reference to the InterCat project: a nationwide experiment to create a database of Internet resources in MARC format, containing description, location and access information (including PURLs = Persitent URLs)). Concludes that descriptive information helps the user identify the works needed, but that it is practical to provide only minimal desriptive information for remote electronic resources in the catalogue record. To a limited extent, the access lost from reduced description can be replaced with new cataloguing techniques designed to stabilize the catalogue record

- Abstract
- Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

- Abstract
- Examines international efforts to promote metadata as a common, interactive resource description tool for the Internet. These efforts centre on the Dublin Core Element Set, but include qualifiers such as those promoted by the Canberra Qualifiers. The LoC Network Development and MARC Standards Office maintains the Dublin Core / MARC / GILS (Government Information Location Standards) crosswalk which maps the common and correlative elements of each system. Describes current international initiatives and issues. Describes the Nordic metadata project which is aiming to create the basic elements of a metadata production and utilization system based on the Dublin Core Metadata Element Set. Describes the WWW consortium efforts in this area

- Abstract
- We propose an extension of a mediator architecture. This extension is oriented to ontology-driven data integration. In our architecture ontologies are not managed by an extemal component or service, but are integrated in the mediation layer. This approach implies rethinking the mediator design, but at the same time provides advantages from a database perspective. Some of these advantages include the application of optimization and evaluation techniques that use and combine information from all abstraction levels (physical schema, logical schema and semantic information defined by ontology). 1. Introduction Although the Web is probably the richest information repository in human history, users cannot specify what they want from it. Two major problems that arise in current search engines (Heflin, 2001) are: a) polysemy, when the same word is used with different meanings; b) synonymy, when two different words have the same meaning. Polysemy causes irrelevant information retrieval. On the other hand, synonymy produces lost of useful documents. The lack of a capability to understand the context of the words and the relationships among required terms, explains many of the lost and false results produced by search engines. The Semantic Web will bring structure to the meaningful content of Web pages, giving semantic relationships among terms and possibly avoiding the previous problems. Various proposals have appeared for meta-data representation and communication standards, and other services and tools that may eventually merge into the global Semantic Web (Berners-lee, 2001). Hopefully, in the next few years we will see the universal adoption of open standards for representation and sharing of meta-information. In this environment, software agents roaming from page to page can readily carry out sophisticated tasks for users (Berners-Lee, 2001). In this context, ontologies can be seen as metadata that represent semantic of data; providing a knowledge domain standard vocabulary, like DTDs and XML Schema do. If its pages were so structured, the Web could be seen as a heterogeneous collection of autonomous databases. This suggests that techniques developed in the Database area could be useful. Database research mainly deals with efficient storage and retrieval and with powerful query languages.

- The PICS, an initiative of W3C, is a technology that supports the association of descriptive labels with Web resources. By providing a single common transport syntax for metadata, PICS will support the growth of metadata systems (including library cataloguing) that are interoperable and widely supported in Web information systems. Within the PICS framework, a great diversity of resource description models can be implemented, from simple rating schemes to complex data content standards

- 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

- The goal of the State Library of Queensland's Metadata Project is the deployment of metadata using the Dublin Core Metadata Element Set in the State Library' WWW Web pages. The deployment of metadata is expected to improve resource discovery by Internet users, through provision of index information (metadata) in State Library Web pages which is then available to search engines for indexing. The project is also an initial attempt to set standards for metadata deployment in queensland libraries Web pages

- Abstract
- Develops frameworks to help Internet media designers address end user information presentation preferences by advancing structures for assessing metadata design variables. Design variables are then linked to user cognitive styles. An underlying theme is that artificial intelligence methodologies may be used to help automate the Internet media design process and to provide personalized and customized experiences. User preferences concerning knowledge acquisition in online experiences provide the basis for discussions of cognitive analysis, and are extended into structural implications for media design and interaction

- Abstract
- The Day was held in Oct 96 to inform about developments in dexcription of electronic documents. Metadata are necessary to aid handling of electronic network resources. A workshop in Dublin Mar 95 compiled 13 elements needed to identify a document-like object, while the Warwick workshop Apr 96 proposed a framework for electronic entries with more metadata types than the Dublin Core. The Nordic Metadata Project aims to evaluate existing metadata format; develop the Dublic Core; make conversion of the Core to the Nordic MARC format possible; and set up a metadata search service for Nordic Internet documents. At the 2nd International Conference on Conceptions of Library and Information Science, Copenhagen Oct 96 a metadata structure for research profiles on Internet homepages was proposed
