The subject of the report is a model of “Z39.50-server + relational DBMS” system: the specificity of requirement processing and reduction of relational data to Z39.50 format. Some complexities appearing in the process of conversion of relational data to hierarchical Z39.50 data schema are examined. Different representations of structured Z39.50 data (GRS-1, SQL-RS, XML) are analyzed. The report is based on the authors’ experience obtained while Z39.50-server named ZooPARK is worked out. The prototype of system is available at http://z3950.uiggm.nsc.ru/zgwk/kadrs.htm.
