1. New Task Group CRIS Architecture & Development Maximilian Stempfhuber RWTH Aachen University Library stempfhuber@bth.rwth-aachen.de

2. Agenda A view to research information The role of CERIF As a data model In the CRIS development process Why a new Task Group? Task Group’s Mission

3. Information & Research Process Work programm Project proposal Project Results Transfer Wealth creation Research organisations Research programmes Research strategy State of the Art Proposal Management Project management (Human)Resources Infrastructure Experiments Publication management Communication Research data Software Prizes, patents Expertise Commercial products Knowledge Wealth Excellence Research Information

5. CERIF A Data Model for CRIS Common European Research Information Format Equipment Project Organisation Service FundingProgramme Patent Skills CV Product Event Person Classification ( Semantics ) Classification ( Semantics ) Publication

6. CERIF A Data Model for CRIS Common European Research Information Format Entity Relationship Model Generators for several DBMS CERIF-XML as exchange format Code of Good Practice Commercial software systems Proprietary implementations

7. Same Model… … different results

8. Current Process Code of Good Practice Organizational view Covers whole process Waterfall-like Missing Aspects (Software) Architecture Technology Reference Implementation

9. Looking Beyond… … the CRIS domain Administrative systems at the institution Local information systems (OAR etc.) Community systems (ResearchGate etc.) Clusters of Excellence (Idea League) Virtual Organizations (Fraunhofer, Helmholtz, Leibniz, Max-Planck)

10. CERIF-CRIS Connectivity CERIF-CRIS Projects, Persons, Org. Units, Publications, Events, Research Programmes, etc. CERIF-CRIS Projects, Persons, Org. Units, Publications, Events, Research Programmes, etc. CERIF-CRIS Projects, Persons, Org.

11. Community CRIS

12. euroCRIS Strategy euroCRIS Enhance existing CRIS Fill gaps with new CRIS Connect CRIS with a common CERIF wrapper Create standardized, reusable services

13. The Gap… CERIF Concrete System Code of Good Practice high low Agreements, Standards, Best Practices, Re-Use … between model and implementation

14. What’s Missing? Operating System Database Management System CERIF Data Access Layer Business Logic User Interface CERIF- XML Search, Harvesting, ServicesCode of Good Practice

15. Why is it important? 20 CERIF : 80 Development & Testing

16. What can be gained… … for euroCRIS as an organization? Community building Exchange Reuse Evolution Spreading ideas & Connectivity … beyond CERIF

17. What can be gained… … for euroCRIS members? Using building blocks Reducing development & testing Getting additional functionality Opening ones system & content … even in combination with commercial software

18. Requirements Requirements engineering (Functional) Software specification Code of Good Practice (Updated) Best Practice Examples / DRIS (Updated) Available (commercial) solutions

19. Database Systems Paradigms (Relational, Object-Oriented, XML, multi-dimensional DBMS) Systems (IBM DB2, Oracle, PostgreSQL; commercial vs. Open Source) Interfaces (ODBC, JDBC, Perl DBI, PEAR) Query languages (SQL, OQL, XQuery) Schema evolution / migration

20. Database Abstraction Separating software architecture from the (physical) database model Encapsulation vs. normalization Object-Relational-Mapping (ORM) Schema evolution / migration Convention over configuration (Coding by convention) & tool support

21. Programming & Managing Re-use of modules and libraries Generating CRIS Open Source code base Share experience with colleagues – Scalability (e.g. middleware) – Reliability (e.g. components) – Integrated Development Environments (IDE) – Development process (SCRUM, V-Model, MDA, …)

22. Software Architecture Permanent evolution vs. re-use – Development philosophy → architecture – Domain modeling → architecture – Software frameworks → architecture – Tools support → architecture – Programming languages → architecture Current buzz words: SOA/REST, Cloud Computing, RIA, BPM, Portal/CMS

23. Functional Modules Self containment Standardized interfaces Standardized functionality Standardized input (e.g. CERIF-XML) Standardized output? CRIS plug-in architecture needed

24. Workflow Business Process Modeling (BPM) Workflows at the UI level Quality assurance in CRIS Event/data-driven services Drives re-usable software modules (e.g. input verification, data acquisition) & processes

25. User Interface Common / consistent user experience Re-use of interaction patterns Sharing solutions (e.g. CSS frameworks) Sharing knowledge (e.g. accessibility) Integration CRISs and services

26. Information Design Common ways for expressing – Semantic relationships – Temporal aspects – Qualities & quantities Software modules for visualizations – Network graphs – Timelines – Charts, … Experiences with commercial software

27. Statistics & Reporting Defining recurring information needs Standardizing on basic data formats Statistics / reporting as a (re-usable / commercial) service Software modules Layout templates (e.g. XSLT, XML FO)

28. External Access Defining public CRIS services – Functional specification – Interface specification – I/O format specification Services – Searching for entities – Data analysis / information extraction

29. Data Exchange Harvesting interfaces Entity extraction Replication Federation Schema mapping

30. TG Roadmap Establishing TG Mission Recruiting TG Members Initial Survey: Where are we now? Where are we going? – Technologies used (DMBS, languages etc.) – Methodologies used (SOA, SCRUM, outsourcing etc.) – Gap analysis: Topics for support & exchange, common modeling of CRIS architectures, abstraction layers, module specifications etc.
