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.

Abstract:

Digital resources of the Russian State Library (RSL) are composed of the Digital Library including 11 collections, the largest of which and the one of the greatest demand is the Digital Dissertation Library, of the RSL Internet Store and of other electronic services. The Russian State Library is in a constant process of broadening its electronic collections, and it would develop the very system of its remote services for readers, too. Thus the RSL makes its contribution to the quality of science and education in Russia, to cultural education of the nation and to creation of a united library and information environment within the state.

Abstract: В работе рассматривается общая архитектура новой версии системы ИСИР, опирающейся на открытые стандарты W3C: Semantic Web [SW], XML[XML] технологии, и на применение opensource решений. Архитектура позволяет разрабатывать распределённые объектно-ориентированные информационные системы - цифровые библиотеки, информационные и корпоративные порталы, сайты на базе различных типов хранилищ информации, таких как объектные и реляционные базы данных, LDAP-каталоги. Система параметризуется описанием объектной схемы данных конкретной предметной области и легко адаптируется к её изменениям. Для описания схемы используется W3C стандарт на описание схем Интернет ресурсов - RDFS. Архитектура имеет многоуровневую модульную организацию, каждый уровень имеет собственные цели и абстракции. Фундамент решения - ядро ИСИР - унифицирует механизмы работы с хранимыми объектными данными, предоставляет ряд услуг по управлению этими данными, например, разграничение прав доступа, журнализация изменений. На базе ядра строятся более высокоуровневые сервисы такие, как RDF/XML-обмен данными, репликация информации между репозиториями, атрибутно - полнотекстовая индексация данных и др. Имеются средства для простой и эффективной разработки пользовательских Web-интерфейсов. Средства публикации информации и построения отчётов применяют механизмы XSLT и поддерживают широкий спектр целевых форматов. Служба управления потоками работ по редактированию ресурсов репозиториев следует стандартам WfMC - канонической модели и языку спецификации потоков работ XPDL. Служба управления содержанием Web-сайта обеспечивает мульти - иерархическую каталогизацию слабоструктурированной информации, отличающейся нерегулярностью взаимосвязи ее элементов.

Abstract:

Interdisciplinary thematic projects implemented by means of the electronic library "Scientific heritage of Russia" allow integrating objects of various nature (printed publications, archival documents, multimedia objects) into a single thematic resource and making it accessible to users. The approaches to the formation of interdisciplinary thematic collections in the digital space of scientific knowledge are investigated. Algorithms for the formation and presentation of a digital interdisciplinary collection are presented. The method of creation and presentation of virtual collections in the information environment of the electronic library "Scientific heritage of Russia". The main types of sections present in most projects are indicated. The main stages of the formation of an interdisciplinary collection in the digital space of knowledge have been formed and described, including the composition of the collection sections, sources for presenting collection materials, dispatching work with sources, the formation of metadata, the main types of sections, etc. An example of the application of the content formation methodology for creating an interdisciplinary collection is given.

Abstract: Digital Archives deal with digital copies of documents, photo, video, audio etc. Traditional form of digital document’s structuring is database based on metadata fields like Dublin Core. A new approach for digital archiving is presented in this paper. This approach consists from two parts: structuring not only documents, but also joint important information and second – following ideas and standards of Semantic Web to provide integration and interoperability of local domains of archive data. A platform solution was designed to support the approach. Several applied systems oriented on accumulation of historical documents and facts were build.
