  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.

  11. Community CRIS

  12. euroCRIS Strategy Enhance existing CRIS Connect CRISwith a commonCERIF wrapper euroCRIS Create standardized,reusable services Fill gaps withnew CRIS

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

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

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

  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.
