Questasy, a DDI based data dissemination tool

Presenter 1
Edwin De Vet

Questasy is a data dissemination tool based on DDI3 developed at CentERdata. It is written in CakePHP and uses a MySQL database. It supports documentation of longitudinal studies as well as the creation of custom datasets. OAI-PMH support for harvesting of studies can be easily set up. The metadata of studies can be exported as DDI 3.1 XML (since version 4.2). Since CakePHP is an MVC framework and supports theming, Questasy can be easily modified to meet specific customer needs. Version 5.0 saw two main features implemented: multilingual support and DDI 3.1 import. For future developments we will investigate whether we can implement DDI 3.2 export and import. Further issues that will be implemented are better documentation of questionnaire routing, summary statistics of variables and dissemination of datasets and syntax created by researchers.
