CSTIT RAS Andrei S. Lopatenko EuroCRIS May Integration of CRIS Reasons –Why we need integrate CRISes Requirements –How we should integrated them –What are primary requirements for integration solution Solutions –What our solution provides new for integration

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Current situation There are a number of CRIS in Europe and national areas (Russian, as example) Usually each CRIS stores geographically local (university, district, country) data. Some of them store sector data scientific data (for innovations only, chemical data) Each CRIS provides a limited number of services The users of CRIS has access to data stored in it only, no CRIS works as a gateway or as a mediator

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Current situation As usual researchers need an access to all information related to their topic, not local only Required information is stored in a number of CRIS To get information researcher need to know about and to have access to a number of CRIS

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Current situation So to give to researcher ability to get required information we should 1.to give him list of all related to his research CRISes(develop CRIS portals) 2.to give him access to CRISes 3.to teach him to work with CRISes Such solution is difficult, expensive, time- consumable, people-consumable and maybe impropriate in some situations

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Example Russian ISIR (Integrated System of Informational Resources) of Russian Academy of Science ( - Central Datawarehouse for RAShttp://isir.ras.ru holds data about Persons, Institutes, Departments, Projects, Publications

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Example ISIR Central Node (Presidium of RAS). Data about all Academy of Science Regional Nodes (Kazan). Data of institutes of Kazan Scientific Center Sectorial Nodes (Mathematics, joint with MathNET, Telecommunications)

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Example Russia Innovation projects of Russian Fund of Basic Research (innovation projects, results, patents) Oriental Studies (epigraphic sources)

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Example Data of Innovation Projects system and regional node of ISIR are a great asset to central node of ISIR, because those data describes activities in Academy of Science Some data (staff) of the central node of ISIR are a great asset for innovation projects system

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Primary requirements Data integration technique should be platform and language independent work in case of independent development of each CRIS able to solve problems of semantic and schematic differences between systems, work in heterogeneous environment with independently developing information systems

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Solution To exchange data between CRIS To use RDF as a language for encoding data To use kernel metadata model(CERIF), which provides basic metadata model for interoperation of CRIS To use application profiles as a method for expanding metadata schemas to application needs

CSTIT RAS Andrei S. Lopatenko EuroCRIS May CRIS-1 CRIS-2 CERIF-RDF Export (with possible transformations) CERIF-RDF Import (with possible transformations)

CSTIT RAS Andrei S. Lopatenko EuroCRIS May RDF for encoding Power of RDF in expressing data. RDF is semantic.RDF is semantic. There is XML encoding of RDF. XML standard applications for signing, linking, identifying, searching, transforming can be applied A lot of developed and emerging tools allow to easily develop solutions on RDF

CSTIT RAS Andrei S. Lopatenko EuroCRIS May CERIF A lot of CRIS store same kinds of data(semantically), which are described in CERIF standard CERIF is about ten-years subject of discussion and using by European CRIS project teams As author experience shows CERIF is detailed enough to define kernel, satisfying needs of CRIS and not detailed so to be schematic conflicted CERIF is multilevel (metadata model, data exchange model, Full model), what makes solution flexible

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Application profiles To combine elements from a number of namespace schemas To override the default definitions of element with a definition that makes sense in a local context. To describe schema of application To specify dependencies among vocabulary terms To define multiple entity classes in a particular data model. To provide guidelines, in free text, about the local use of particular terms

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Developing application-specific schemas Need to specify a set of elements and their properties Need to specify restrictions/integrity rules Need to specify which vocabulary and where Need to specify relation between elements

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Problems There can be semantic and schematic differences between namespaces

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Our application profiles consist of. A set of included namespaces Definitions semantic relations between elements from different namespaces Overriding definition of elements Vocabularies definitions and vocabularies content Definitions semantic relations between elements from different vocabularies Rules for resolving semantic and schema conflicts

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Application profiles. Advantages Allow to reuse schemas Proved to be useful (SCHEMAS, UKOLN DESIRE, Z39.50 applications) Close to Digital Library projects such as Digital Library Warwick Framework

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Current state Have developed 1.RDF schema for CERIF. 2.importing and exporting tools from CERIF database (published on cordis) into CERIF RDF 3.vocabulary tools 4.application profiles managing tools

CSTIT RAS Andrei S. Lopatenko EuroCRIS May Representing CERIF in RDF. Possible usage Data exchange between CRIS Semantic representation of research data in the web pages for data gathering. RDF-DC is not sufficient Translating data into RDF for additional functionality, which can not be provided by CRIS. Developing Value-added services

CSTIT RAS Andrei S. Lopatenko EuroCRIS May CRIS Database RDF generation Application profile For data exchange (based on CERIF) Database Description (schematic) Java, Xerc, ODBC tools Generation rules Schema Transformation, Vocabuly mapping CRIS data RDF encoded CRIS data Exporting RDF
