用VFP实现对MARC记录中任意字段的读取

通过对MARC记录存放格式的分析，介绍使用VFP开发环境从MARC记录中任意读取各字段数据的一种方法。     

论基本元数据核心集与MARC互换的可行性

当前网络信息资源组织方面最突出的问题就是如何使用元数据合作描述网络资源,解决异构数据库相互转换等问题。本文概述了MARC的缺陷和DC的优势,提出CNMARC向DC转换的必要性,详细列出DC元素与MARC各字段映射关系,同时分析了MARC与DC互换的可行性。     

基于XML／RDF的MARC元数据描述技术

由W3C推出的元数据标准可扩展标记语言XML和资源描述框架RDF分别规范了Internet上资源描述的语法和语义,为元数据的编码、交换和重用提供了基础架构。本文针对目前广泛存在于图书馆系统中的MARC格式的大量书目数据,研究了基于XML／RDF的MARC元数据描述技术,重点解决了MARC元数据的XML描述问题和基于RDF的MARC元数据描述问题,从而使得专用的MARC规范格式的书目数据转换成通用的机器可读和机器可理解的元数据成为可能。本文的研究成果对于现有MARC数据在未来数字图书馆中的利用具有重要意义。     

From MARC to BIBFRAME 2.0: Crosswalks

ABSTRACT

One of the big challenges facing academic libraries today is to increase the relevance of the libraries to their user communities. If the libraries can increase the visibility of their resources on the open web, it will increase the chances of the libraries to reach to their user communities via the user's first search experience. BIBFRAME and library Linked Data will enable libraries to publish their resources in a way that the Web understands, consume Linked Data to enrich their resources relevant to the libraries' user communities, and visualize networks across collections. However, one of the important steps for transitioning to BIBFRAME and library Linked Data involves crosswalks, mapping MARC fields and subfields across data models and performing necessary data reformatting to be in compliance with the specifications of the new model, which is currently BIBFRAME 2.0. This article looks into how the Library of Congress has mapped library bibliographic data from the MARC format to the BIBFRAME 2.0 model and vocabulary published and updated since April 2016, available from http://www.loc.gov/bibframe/docs/index.html based on the recently released conversion specifications and converter, developed by the Library of Congress with input from many community members. The BIBFRAME 2.0 standard and conversion tools will enable libraries to transform bibliographic data from MARC into BIBFRAME 2.0, which introduces a Linked Data model as the improved method of bibliographic control for the future, and make bibliographic information more useful within and beyond library communities.     

Metadata Dreaming

ABSTRACT

The author presents the state of metadata schemes today and discusses the idea of a “third way” between free-text searching and full cataloguing. He concludes that there is no such compromise and suggests that metadata schemes will have to incorporate controlled vocabularies and detailed designators if they are to progress, thus leading to a confluence that will be, in essence, a new form of traditional cataloguing.     

将简单文本书目库转换成标准MARC数据库的实践与思考

机读目录的检索原理与功能

检索是书目的主要功能之一,著录信息中相当大部分与检索点密切相关。当今,书目形式已由传统的书本式、卡片式向机读式发展,检索过程也由人工查检改进为计算机操作。然而,从一些文献编目规则的制定和编制的机读目录数据来看,存在与计算机特点脱节的情况,影响了机读目...

Automatically Batch Loading Metadata from MARC into a Work-Based Metadata Model for Music

This article describes work done at Indiana University to “batch load” data from MARC bibliographic and authority records into the Work-based and FRBR-like Variations system. A series of experiments to iteratively refine our batch loading algorithm is described, along with details of how the algorithm identifies Works, creates relationships between entities, and maps a large amount of data from MARC into Variations records. The article closes with a discussion of the potential impact of this work on Variations project workflow and community FRBRization activities.     

浅谈CNMARC与MARC21

Fixed Fields Coded Data for Geo-Related Information in the MARC21 Structure: A Discussion on the Possible Expansion of Coded Data Elements to Improve Machine Manipulation and User Discovery

Patrons of map collections often have specific, geographically-based, requests for maps and the information they provide. Map librarians can often meet these needs through personal knowledge of the scope of their collections. For larger collections, this method is unsustainable. This article, therefore, seeks to begin a discussion on how coding could be used to expand the ability of our patrons’ online information seeking methods to meet their information needs.
