Groovy and Grails Meet Eclipse Modelling Framework

This paper presents an approach to combine model-driven engineering with a popular web framework. In particular, it presents a case study of an implementation of the newest version of Noark 5, the Norwegian standard for archives in the public sector. In this project the data objects are modelled in the Eclipse Modelling Framework and the implementation is based on Groovy and the Grails web framework. This paper also describes the EMF2GORM tool, which is developed in order to automatically generate data classes for Grails. In addition to supporting simple classes and relations between them, this tool also supports setting other properties and constraints such as specifying that a data class should be available for free-text searching and specifying constraints that span over multiple model elements.
