XML SCHEMA OF UNIMARC FORMAT VARIANT AND BIBLIOGRAPHIC RECORD IN BISIS SOFTWARE SYSTEM 1
Branko Milosavljević, Bojana Dimić Surla · 2007
BISIS library software system is based on a UNIMARC format variant called YUMARC format. An XML schema for description of the YUMARC format as well as an XML schema of the record formed in accordance with the YUMARC format are proposed in the article. MARC (Machine Readable Cataloguing) bibliographic format (1), as a format for recording and exchange of bibliographic data in a machine-readable form, has represented a basis for deflning other bibliographic MARC formats intended for the needs of library systems in difierent countries. The UNIMARC (Univer- sal Machine Readable Cataloguing) format was one of the formats developed for European countries (2). As a universal cataloguing format of bibliographic ma- terials, this format enables exchange of data in a machine-readable form among national and international bibliographic institutions. A connection between the structure of bibliographic records and the struc- ture of an XML document was noticed in early phases of the XML technology development. One of the common points is the existence of the elements which can be mandatory or optional, repeatable or divided into subelements. Every XML structure can be formally described by using the XML schema that is deflned by the XMLSchema language (3). The rules for creating XML schema correspond to the rules for creating the structure of the bibliographic records prescribed by some of the library standards. The biggest advantage of using XML for representing bibliographic data is re∞ected in simpler data processing in open distribution systems. The already developed software tools for work with XML documents are also to be credited for this. The BISIS library software system has been in the process of development at the Novi Sad University since 1992, and several versions have been made so far (4). The system is based on the UNIMARC format, is supplemented for 1 The work is supported by the Ministry for Science, Technologies and Development of the
