Приведены алгоритмы создания метаописания ретро-коллекций, основанные на анализе структуры математических документов и применении программных инструментов выделения метаданных. Дано описание ретро-коллекций, сформированных с помощью разработанных алгоритмов и включенных в состав фабрики метаданных цифровой математической библиотеки Lobachevskii-DML. Указаны схемы формирования метаданных и методы нормализации извлеченных метаданных в соответствии со схемами и требованиями интегрирующих математических библиотек.

Algorithms for creating a meta description of retro collections based on the analysis of the structure of mathematical documents and the use of software tools for extracting metadata are given. The description of retro-collections formed using the developed algorithms and included in the metadata factory of the digital mathematical library Lobachevskii-DML is given. The schemes for the formation of metadata and methods for normalizing the extracted metadata in accordance with the schemes and requirements of the integrating mathematical libraries are indicated.
