Blaise 5.0.4 - The November 30th 2015 release

intro blaise release 5 0 4It's almost December. Time to release a new version of Blaise!

This version includes the second version of Manipula, which is now production-ready, the first version of CATI, Multi-mode support, User-defined special attributes, and a few smaller additions. Furthermore, we have worked on performance enhancements, improved the iOS and Android apps, and solved many issues that were reported by our users.


manipulaThe second version of Manipula is now available. In this version we have implemented support for AUTOREAD=NO, update files, temporary files, variable meta and it is now possible to define a datamodel in the uses section of your manipula setup.


cati1This release offers a first step toward a version of CATI (Telephone Interviewing) that offers functionality comparable to Blaise 4 CATI. In this release the focus is on the functionality that is needed for auto delivery of a case to an interviewer. We have implemented the CATI specification, daybatch creation and the call scheduler. We also offer a first version of a CATI management dashboard. We have shipped an example with the system that shows how Blaise 5 CATI works.

Multi-Mode Support

Blaise 5 now truly supports multi-mode questionnaires, by adding the modes keyword to the language. In your datamodel, you define the modes in which this questionnaire can run. Every mode can have its own set of allowed special answers. Based on the mode, different routing is possible as well. Also, different texts are possible in different modes (e.g. question texts, answer options, etc.)

User Defined Special Attributes

Blaise 5 now allows the questionnaire designers to add their own special attributes (e.g. NA). These special attributes can be used in the same way as the standard special attributes (DK and RF).

Browser Page Preview

browser previewIt is now possible to preview the page you are designing in a browser. When you switch to the Layout view of a datamodel, you will see a preview icon appear in the list of shortcut icons on the top of the Control Centre. Using that icon, you can preview the current page in any of the browsers installed on your system.

Watch Window

The Session Viewer has been extended with functionality to see the state of a particular session. You can select fields to watch, and you can compare two states to see what was changed since the last update.

Support for a custom relational database for session and audit trail data.

Actions for parallels

For a Parallel, actions can be specified in the OnEnd property. These actions will be executed when the end of the parallel is reached. The Finish action has been added to allow to end the interview (similar to when the end of the main parallel is reached).
