Clasificaciones Facetadas y Metadatos (I): Conceptos Básicos

Los metadatos son información relativa a otra información. Al definir un grupo de metadatos para un objeto dado, estamos describiendo el objeto en cuestión, lo estamos caracterizando. Por ejemplo, HTML permite definir metadatos para una página web a través de su etiqueta . Esos metadatos (author, keywords...) caracterizan la página, describen su contenido. Los metadatos, utilizados tradicionalmente en el entorno bibliotecario, están resultando de gran utilidad en la Web, tanto en Sistemas de Recuperación de Información (back-end) como en Sistemas de Navegación (front-end).

La Classificazione Come Investimento Nella Qualità dell'Informazione

La classificazione rappresenta un investimento che comporta dei costi nel breve termine, ma che dà anche notevoli frutti nel lungo termine (se impostata correttamente). Fra i sistemi di classificazione, quello a faccette (o multidimensionale) è sicuramente il più potente e versatile (nonostante gli schemi affermatisi come standard nella maggioranza delle biblioteche sono assai distanti da quello a faccette).

Controlled Vocabularies: A Glosso-Thesaurus

'There is a singular lack of vocabulary control in the field of controlled vocabularies,' Bella Hass Weinberg, professor of library science at St. John's University in New York, is fond of saying. To help you cut through the maze of verbiage often found in this field, we have created a glossary of terms.

Designing a New Schema with XML Design Patterns

Proposes the design of an XML-based type library format. If you've had exposure to Microsoft COM or Mozilla's XPCOM, you're probably familiar with their binary TLB (MS) and XDT (Mozilla) formats that define the available operations and interfaces for a package of portable components. An interpreted language such as JavaScript can use these definitions as cheat sheets to find out what operations and parameters are available to call on-the-fly.

The Evolving Metadata Architecture for the World Wide Web: Bringing Together the Semantics, Structure and Syntax of Resource Description

The Dublin Core is currently the best-developed candidate for a simple resource description model for electronic resources on the Web. It represents the results of a three year process of consensus-building through a series of focussed, invitational workshops involving librarians, digital library researchers, and various content specialists from many countries.

Extending the Warwick Framework

This paper presents 'Distributed Active Relationships' (an extension of the Warwick Framework), a general framework for dealing with meta data issues in digital libraries and other information systems. By treating meta data as data, rather than giving it a special distinguished role, arbitrary resources are allowed to be associated with arbitrary relationships.

From Structured Abstracts to Structured Articles: A Modest Proposal    

Work with structured abstracts--which contain sub-headings in a standard order--has suggested that such abstracts contain more information, are of a higher quality, and are easier to search and to read than are traditional abstracts. The aim of this article is to suggest that this work with structured abstracts can be extended to cover scientific articles as a whole. The article outlines a set of sub-headings--drawn from research on academic writing--that can be used to make the presentation of scientific papers easier to read and to write. Twenty published research papers are then analyzed in terms of these sub-headings. The analysis, with some reservations, supports the viability of this approach.

An Introduction to Metadata

Metadata is structured data which describes the characteristics of a resource. It shares many similar characteristics to the cataloguing that takes place in libraries, museums and archives. The term 'meta' derives from the Greek word denoting a nature of a higher order or more fundamental kind. A metadata record consists of a number of pre-defined elements representing specific attributes of a resource, and each element can have one or more values.

Keyword Perspective: Avoid This Mistake At All Cost

In this article, we are going to discuss a major problems involving keyword selection for existing businesses. It is a simple mistake, but one most people do not think about. The two prime Internet marketing platforms are pay-per-click advertising and search engine optimization. The issue we are going to discuss today applies equally to either of these platforms as well as any other internet advertising you undertake.

A Knowledge Network Constructed by Integrating Classification, Thesaurus and Metadata in a Digital Library

Knowledge management in digital libraries is a universal problem. Keyword-based searching is applied everywhere no matter whether the resources are indexed databases or full-text Web pages. In keyword matching, the valuable content description and indexing of the metadata, such as the subject descriptors and the classification notations, are merely treated as common keywords to be matched with the user query. Without the support of vocabulary control tools, such as classification systems and thesauri, the intelligent labor of content analysis, description and indexing in metadata production are seriously wasted.

Metadata Generation: Processes, People and Tools

Metadata generation is the act of creating or producing metadata. Generating good quality metadata in an efficient manner is essential for organizing and making accessible the growing number of rich resources available on the Web. The success of digital libraries, the sustenance of interoperability – as promoted by the Open Archives Initiative – and the evolution of Semantic Web all rely on efficient metadata generation. This article sketches a metadata generation framework that involves processes, people and tools. It also presents selected research initiatives and highlights the goals of the Metadata Generation Research Project.

Metadata Leadership

Libraries must increasingly accommodate bibliographic records encoded with a variety of standards and emerging standards, including Dublin Core, MODS, and VRA Core. The problem is that many libraries still rely solely on MARC and AACR2. Meanwhile, the world of information is passing us by. How important is this problem? There are now literally millions of useful online items that lack MARC cataloging and will likely never be cataloged in MARC. We ignore these resources at our peril. Our users will justifiably seek assistance elsewhere, as many already have. Ignoring the problem will only make libraries increasingly marginalized. What are we to do?

New Metadata Standards for Digital Resources: MODS and METS

Metadata has taken on a new look with the advent of XML and digital resources. XML provides a new versatile structure for tagging and packaging metadata as the rapid proliferation of digital resources demands both rapidly produced descriptive data and the encoding of more types of metadata. Two emerging standards are attempting to harness these developments for library needs. The first is the Metadata Object and Description Schema (MODS), a MARC-compatible XML schema for encoding descriptive data. The second standard is the Metadata Encoding and Transmission Standard (METS), a highly flexible XML schema for packaging the descriptive metadata and various other important types of metadata needed to assure the use and preservation of digital resources.
