Basic Services of Factory Metadata Digital Mathematical Library Lobachevskii-Dml

Abstract

A number of problems related to the construction of the metadata factory of the digital mathematical library Lobachevskii-DML have been solved. By metadata factory we mean a system of interconnected software tools aimed at creating, processing, storing and managing metadata of digital library objects and allowing integrating created electronic collections into aggregating digital scientific libraries. In order to select the optimal such software tools from existing ones and their modernization:we discussed the features of the presentation of the metadata of documents of various electronic collections related both to the formats used and to changes in the composition and completeness of the set of metadata throughout the entire publication of the corresponding scientific journal;we presented and characterized software tools for managing scientific content and methods for organizing automated integration of repositories of mathematical documents with other information systems;we discussed such an important function of the digital library metadata factory as the normalization of metadata in accordance with the formats of other aggregating libraries.As a result of the development of the metadata factory of the digital mathematical library Lobachevskii-DML, we proposed a system of services for the automated generation of metadata for electronic mathematical collections; we have developed an xml metadata presentation language based on the Journal Archiving and Interchange Tag Suite (NISO JATS); we have created software tools for normalizing metadata of electronic collections of scientific documents in formats developed by international organizations – aggregators of resources in mathematics and Computer Science; we have developed an algorithm for converting metadata to oai_dc format and generating the archive structure for import into DSpace digital storage; we have proposed and implemented methods for integrating electronic mathematical collections of Kazan University into domestic and foreign digital mathematical libraries.

Digital Libraries and the Common Digital Space of Mathematical Knowledge

“…One of the basic directions of research developed within the framework of this digital mathematical library is associated with the development of a system of interconnected software tools that ensure the creation, processing, storage, management of metadata of digital library objects and the integration of created electronic collections into digital scientific libraries that aggregate them. We call the system of such tools a metadata factory [48,49].…”

“…As a result, the developed tools of the metadata factory of the digital mathematical library Lobachevskii-DML became (see [48]):…”

“…The initial sets of metadata used in the conversion to the named format were generated automatically using the software tools developed by us, taking into account the specifics of the Open Journal Systems software platform [59] on which this journal operates. The algorithm for translating this metadata into the DBLP format has been successfully implemented; it is described in detail in [48,56].…”

Algorithms for Integration of Unstructured Mathematical Documents into the Common Digital Space of Scientific Knowledge

“…The works [16,17] describe methods of forming metadata of digital collections using the tools of the metadata factory of the digital library Lobachevskii-DML. The implementation of these tools is based on methods for analyzing the structure of documents (see, for example, [18][19][20][21][22][23]).…”

“…The Journal Archiving and Interchange Tag Suite (NISO JATS) xml schemas have been developed to represent the metadata of articles in periodicals and are used in a number of digital mathematical libraries (see, for example, [16,[33][34][35]). In the EuDML project based on NISO JATS V1.0, three sets of metadata are distinguished: obligatory metadata, fundamental metadata, and supplemental metadata (see [28,36,37]).…”
