09/12/20133 The Unified Research Information Space (URIS) The Unified Research Information Space (URIS) of the Russian academy of Sciences (RAS) is an integrated information space of distributed and local digital resources of RAS organizations and hardware and software tools that support its functionality and control.
09/12/20134 The main tasks of URIS RAS Development of a unified metadata model on the basis of modern technologies and implementation of a global search mechanisms on its; Active scientific communications; Building of distributed catalogs of scientific information; Information support of research study; Development and publication of corporate standards; Development and implementation of a software package The RAS Basic Institution; Construction of points for access these information (portals); Implementation of access and integration to information resources of RAS organizations; Security support; Interconnection with other information systems.
7 URIS Information Bus The basis of the URIS RAS is an Information Bus that is a set of hardware, software and administrative tools that support: Resources and services supplement Security Metadata actualization Data integration Global search.

09/12/ Technologies The information model of URIS RAS is based on Semantic Web – RDF, RDFS, OWL ontology of scientific information. This includes: Scientific activity, in particular projects as a process, conferences, seminars etc. Participants of Scientific activity, like persons, working groups, organizations etc. Results of Scientific activity, like data bases, software projects, innovations etc. Documents and publications, like papers, dissertations etc
09/12/ URIS Metadata requirements Include basic resource types Provide access to resources Provide extensibility Provide data integration Provide identification Provide searching in distributed environment Use Semantic Web approach. Provide interoperobility
09/12/ URIS Metadata standards Semantic Web – RDF, RDFS, OWL DCMI - Dublin Core Metadata Initiative (dublincore.org)dublincore.org PRISM - Publishing Requirements for Industry Standard Metadata (Adobe,…) AGLS Metadata Standard vCard – visit card in RDF. FOAF open initiative Friend Of A Friend ( personal information) BIBLINK, bibTeX, Math-Net, UKOLN CLD … CERIF 2000, MARC и RUSMARC, CIDOC …
09/12/ Metadata Scheme levels Metadata definitions are divided into schemes according to: – Application fields (AF) – Levels of description.
09/12/ The basic metadata profile General purpose elements Academic data Historical aspects The minimal description of person The minimal description of an activity The minimal description of results of activity
09/12/ Special profiles Bibliography Information about developments and products Mathematics Conferences Collections and archives Library Publishing
09/12/ Scheme levels ·Minimal – sufficient to exchange data; ·Base – minimal sufficient for an application field; ·Extended – sufficient for an application field; ·Special – full description of an application field.
09/12/ RAS institutions information tasks Inner administrative tasks Institution as a research RAS organization Support of a research process Public representation
09/12/ The software package RAS Institution The software package The RAS Institution is intended to supply institutions with a modern information system that supports internal requirements (publication of scientific information, administrative processes and information etc.) from one hand, and external ones (representation of the information in URIS RAS and Internet) from another hand. It includes: Infrastructure services that supports Data storage Global identification Data exchange and replication Security Indexing and search.
09/12/ The software package RAS Institution Base components include subsystems Administrative directory Publications Projects. Interaction components News Forums Private communication Application components Publishing department Library Electronic library Library of dissertations.
09/12/ Base components CMS – Content management system Resource library (pictures, files) Organization directory Publications Projects
09/12/ Services Access control Indexing and searching Data exchange News Forums Private communication (P2P)
09/12/ Application components Digital library Publishing Library Library of dissertatios
09/12/ RAS institution applications Portal RAS RAS organizations information systems Thematic information systems Bridges
09/12/ Purposes –Metadata support (keeping and editing) –Metadata harvesting –Integration of scientific spatial data –Searching of spatial data and services –Spatial data visualisation (maps, pictuers etc)
09/12/ Architecture Implementation is based on RAS Institution Ontology is based on EIS Includes extensions for ISO 19115/19119 standards
