Popis: Описаны технологические подходы, применяемые для создания распределенных информационных систем поддержки научных исследований. Рассмотрены архитектурные решения, разработанные для создания таких систем и принципы интеграции этих систем с внешними источниками. Определены функциональные требования к модели такой информационной системы, которые обусловлены, во-первых, информационными потребностями исследователей, а во-вторых, необходимостью обеспечения надежного и долговременного хранения информации. Рассмотрены правила представления и преобразования метаданных. Описан и реализован прототип такой системы.
The article addresses the description of technological approaches used to create distributed information systems for supporting scientific research. We describe the developed architectural solutions which are intended to create such systems and the principles for integrating of these systems with the external sources. The functional requirements for the model of such an information system are determined. These requirements are determined, firstly, by the information needs of researchers, and secondly, by ensuring a reliable and long-term storage of information. The considered model of SIS is implemented in the form of a prototype of the Electronic Library Management System (ELMS IRIS). ELMS IRIS operates with electronic collections. The electronic collection is considered as a set of information objects, united on a semantic basis and having the same structure (data schema). An ELMS allows to work with two types of collections which are the catalogs and the thesauri. The rules of representation and transformation of metadata are discussed. In order to organize metadata exchange between repositories and a metadata server (as well as with other systems with an extended profile), a special service is created that converts metadata from the internal schema into other metadata schemes. The OAI-PMH service is implemented, which periodically synchronizes the metadata of the repository and the metadata server in accordance with the schedule in batch mode. To fill the “Main metadata catalog”, in accordance with the metadata schemas created, managed dictionaries are used from the reference support block. To ensure data interoperability, the application server based on ZooPARK-ZS is also implemented, which provides access to system metadata via Z39.50 and SRW/SRU protocols. The developed model can be used as a model of the system for working with documents related to scientific and educational activities, since it solves the main tasks for these systems which are to provide a system for reliable long-term storage of digital (electronic) documents while preserving all the semantic and functional characteristics of source documents as well as ensuring “transparent” search and access of users to documents. These actions are necessary both for familiarization and for the analysis of the facts contained therein; and organization of collection of information on remote digital repositories supporting protocols OAI-PMH, SRW/SRU, Z39.50.
