The aim of this paper was not only to define the XML bibliographic records format, but also to describe the use of different XML standards and off-the-shelf tools in library automation. The quality control system of bibliographic records within the BISIS library software system has been implemented using XML Schema, XSLT and XPath languages, according to UNIMARC bibliographic format. The paper describes the possibility of using XML in bibliographic record control. The categorization of UNIMARC bibliographic records verifications, that could help to determine record quality, is discussed. Additionally, it describes XML schema for XML format used in the BISIS system. The XML schema and XSLT expressions for additional control of bibliographic records present the basis of XML bibliographic record quality control system. A prototype of this system is implemented in the Java programming environment, independently from bibliographic format, using XML validation, parsing and transformation tools. Thus, it may be used for performing XML bibliographic record quality control, which have different bibliographic formats, using XML schema and XSLT expressions specified in the paper.
