C ommon E uropean R esearch I nformation F ormat – A Concept about Research Entities and their Relationships Specification (Conceptual Level) – An abstract formal description of the concept about entities and their relationships Model (Logical Level) – A formal machine readable description of the concept Database Scripts (Physical Level) SQL Script CREATE Table Person CREATE Table Project CREATE Table OrgUnit Organisation of Data / Information accordingly !!

C ommon E uropean R esearch I nformation F ormat (1) data model ( conceptual, logical, physical ) (2) allows for a ( metadata ) representation of –research entities –their activities / interconnections (research) –their output (results) (3) allows for high flexibility with formal semantic relationships enables quality maintenance, archiving, access and interchange of research information supports knowledge transfer to decision makers, for research evaluation, research managers, strategists, researchers, editors, the general public
