DDI Controlled Vocabularies (CVs)

Overview

What is a controlled vocabulary?

This collection documents web services (APIs) available for DDI Alliance Controlled Vocabularies (CVs) that have been created by the DDI Controlled Vocabularies Group (CVG).
A full list of DDI CVs, with information on concepts covered and available versions, can be found at DDI Alliance Controlled Vocabularies (CVs).

Many of the DDI Alliance vocabularies are already in use worldwide - across Europe, by countries belonging to the Consortium of European Social Science Data Archives (CESSDA), in the United States by the Inter-university Consortium for Political and Social Research (ICPSR), and Mathematica Policy Research, in Canada, etc. DDI Controlled Vocabularies are also incorporated in editing and publishing tools that work with the DDI specification, like Colectica and Nesstar Publisher.

Formats

From this Postman collection, the DDI CVs are published as SKOS in the following serialisations: JSON-LD, N-Triples, Turtle, and RDF/XML.

HTML and PDF and XML versions can be retrieved from the website at : DDI Alliance Controlled Vocabularies (CVs).

Usage

Usage information for each controlled vocabulary is available in the vocabulary documentation at DDI Alliance Controlled Vocabularies (CVs). This includes instructions specific to DDI Lifecycle and recommendations, with examples, for how to cite the CVs outside the DDI. The published DDI CVs work with both versions of the DDI specification.
