Developing Products of the Alliance
Developing New DDI Products
The DDI Alliance continues to develop new products to meet the needs of current and potential user group. These are proposed by members and supported by contributed work and funding from the Alliance as agreed to by the Executive Board. New products may be used to expand the coverage of existing DDI products or be published as stand-alone products that address a need in the DDI Community.
Development of a number of RDF Vocabularies as well as an expansion of the role of RDF in DDI products began in a workshop on "Semantic Statistics for Social, Behavioural, and Economic Sciences: Leveraging the DDI Model for the Linked Data Web" at Schloss Dagstuhl - Leibniz Center for Informatics, Germany, in September 2011. This work continued with follow-up workshops and focused product meetings.
A major development effort starting in 2013, entitled the "Moving Forward Project," resulted in new content and production approaches in existing products as well as new product development.

| Disco | This specification is designed to support the discovery of microdata sets and related metadata using RDF technologies in the Web of Linked Data. The vocabulary leverages the DDI specification to create a simplified version of this model for the discovery of data files. It is based on a subset of the DDI XML formats of DDI-Codebook and DDI-Lifecycle. |
