Metadata Normalization Methods in the Digital Mathematical Library

Methods for the automatic generation of metadata for documents in digital mathematical collections in the formats of international resource aggregators in mathematics and Computer Science are proposed. Metadata normalization services for electronic collections of scientific documents in accordance with DTD rules and XML schemas Journal Archiving and Interchange Tag Suite (NISO JATS) V1.0, V1.1, V1.2 have been created. Algorithms for creating electronic collections and including them in the digital mathematical library are presented. Tools for generating metadata of collection documents in accordance with the syntactic rules of digital libraries have been developed. An algorithm for the automated preparation of metadata of electronic collections of the Lobachevskii DML library according to the rules of the dblp Computer Science Bibliography (DBLP) bibliographic database on computer sciences is given. An algorithm for converting metadata to the oai_dc format and generating the archive structure for import into DSpace digital storage has been created. Methods for integrating electronic mathematical collections of Kazan University into Russian and foreign digital mathematical libraries have been proposed and implemented.
