It was primarily developed for the LISS Data Archive, but was designed to be repurposed for other surveys. The structure of the application, from the underlying database to the generated Web pages, is based on DDI 3. This paper describes how Questasy was designed and implemented.

The tool plays a critical role in the work flow at the DDA, providing needed integration of information. The design decisions made during development may be instructive for others building tools based on DDI 3.

ABSTRACTA questionnaire is usually revised several times during construction, and documenting those revisions in detail is important for understanding the lineage of the questions asked and for further questionnaire development in future studies. This documentation is also indispensable for teaching survey research methods.Nonetheless, this documentation is usually done only partially or not at all, due to a lack of useful documentation tools. The aim of the Questionnaire Development Documentation project was the development of a system to permit permanent electronic documentation of questionnaire development and the final state of the instrument.QDDS is a useful and effective system but may be improved by moving to DDI 3 to take advantage of enhanced functionality, especially in terms of versioning. DDI 3 also has the potential to provide the framework for a question bank.

The Data Documentation Initiative (DDI) metadata specification 6 is expressed in the form of XML schema. With version 3, the DDI specification has become quite complex, including 21 namespaces and 846 elements 7 . Organizations employing DDI, or considering doing so, may want to 1. store and manage the metadata elements in relational databases, for reasons of integration with existing systems, familiarity with the concepts of relational databases (such as Structured Query Language), systems performance, and/or other reasons; 2. select only the subset of the available DDI metadata elements that is of utility to their work, and have the flexibility of capturing metadata they need that would not fit into the DDI model. This paper discusses advantages and disadvantages of the relational database approach to managing DDI. It also describes methods for modeling DDI in relational databases and for formally defining subsets of DDI to employ in this environment.1 CentERdata [a.amin@uvt.nl]
