Application of Kroki Mockup Tool to Implementation of Executable CERIF specification

Abstract

The paper presents application of Kroki tool to create an executable specification of the CERIF standard. Kroki (fr. croquis – sketch) is an open-source tool that is being developed in order to foster development agility and better communication among team members with different specialties. It can be used for creating specifications of data-driven applications using two different notations (UML based and mockup based) and for generating application over the specification. This paper presents usage of Kroki tool for visualization and further development of CERIF data model, as well as the use of Kroki for generating a prototype of a CRIS system over the CERIF data model. The CERIF 1.5 specification was taken from the euroCRIS web site and entered into the Kroki tool. More than 280 CERIF classes are divided into 31 packages, in order to make CERIF model easier to read and comprehend. Thanks to its mockup and lightweight UML editor, Kroki enables each user, with or without background in information technologies, to understand and change the CERIF specification.
