XML schema for UNIMARC and MARC 21

Abstract

Purpose

The purpose of this paper is to create a model for an XML document that will carry information about bibliographic formats. The model will be given in the form of an XML schema describing two bibliographic formats, UNIMARC and MARC 21.

Design/methodology/approach

The description of bibliographic formats using the XML schema language may be discussed in two ways. The first one relates to creating an XML schema in a way that all elements of the bibliographic format are described separately. The second way, used in this paper, is creating an XML schema as a set of elements that presents concepts of bibliographic formats. A schema created in the second way is appropriate for use in implementation of cataloguing software.

Findings

The result is an XML schema that describes MARC 21 and UNIMARC formats. The instance of that schema is an XML document describing a bibliographic format that will be used in software systems for cataloguing. An XML document that is an instance of the proposed XML schema is applied in the development of the editor for cataloguing in the BISIS library information system. This XML document represents input information for that editor. In this way, the implementation of the editor becomes independent of the bibliographic format.

Practical implications

The created XML schema cannot serve as an electronic manual because there is some information about the format that is not included in it. In order to overcome this shortcoming an additional XML schema that will contain remaining format data may be provided.

Originality/value

The originality lies in the idea of creating one XML schema for two bibliographic formats. The schema contains elements that are models for data used in cataloguing tools. On the basis of that XML schema, the object model of bibliographic formats is implemented as well as software component for manipulating format data. This component can be used in development of library software systems.
