DDI Working Paper Series

The DDI Working Paper Series (ISSN 2153-8247) is intended as a dynamic publication avenue for authors working in the DDI space. Currently, the series includes papers on new and emerging themes as well as papers on best practices and use case literature.

If you are interested in publishing a paper to be part of the DDI Working Paper Series, please contact the DDI Alliance Director.


Best Practices

[Insert other papers here]

Best Practices Across the Data Life Cycle

These Best Practices provided reflect the work of 25 individuals who came together in a workshop at Schloss Dagstuhl, in Wadern Germany, in November 2008. The documents are the first attempt to define procedures for using DDI optimally and as such are not considered "final."

Best Practices for Longitudinal Data

The first four of these papers on using DDI to document longitudinal data are the outcomes of a workshop held at Schloss Dagstuhl - Leibniz Center for Informatics in Wadern, Germany, October 18-22, 2010. Workshop participants representing seven countries came together to write the papers, which focus on applying DDI 3 to complex, longitudinal data. The fifth paper on the Generic Longitudinal Business Process Model was an outcome of a workshop held the following year.

The best practice authors and editors welcome your feedback on the usability of the documents and priorities for new best practices. Please send your comments and suggestions to ddi-bp-editors@icpsr.umich.edu

Use Cases

These papers on DDI 3 use cases are the outcomes of a workshop held at Schloss Dagstuhl - Leibniz Center for Informatics in Wadern, Germany, November 2-6, 2009. Workshop participants representing nine countries in the Americas and Europe came together to write the papers, which focus on applying DDI 3 to specific projects and systems.

Questasy: Documenting and Disseminating Longitudinal Data Online Using DDI 3

This paper describes how Questasy, a Web application developed to manage the dissemination of data and metadata for panel surveys, was designed and implemented.

Building a Modular DDI 3 Editor

This paper focuses on the creation of an open source DDI 3 editor built using a layered architecture at the Danish Data Archive (DDA).

Using DDI 3 for Comparison

This paper explores how archives can use DDI 3 to support and document data comparison and harmonization.

Extracting Metadata From the Data Analysis Workflow

This paper is an exploration of what metadata can be harvested from several commonly used programs, and therefore by deduction what else is not available from these programs.

Questionnaire Management and DDI: The QDDS Case

This paper describes the Questionnaire Development Documentation project, a system created by GESIS – Leibniz Institute for the Social Sciences to permit permanent electronic documentation of questionnaire development and the final state of the instrument.

Grouping of Survey Series Using DDI 3

This paper is an exploration and evaluation of DDI 3 to determine its suitability for marking up and managing cross-national comparative surveys like the International Social Survey Programme data.

An Archive's Perspective on DDI 3

This paper describes the DDI 3 evaluation process at the Finnish Social Science Data Archive (FSD), and the issues that came up during this work, including how to address multilinguality and metadata reuse.

Semantic Web

These papers on DDI and the Semantic Web are the outcomes of a workshop held at Schloss Dagstuhl - Leibniz Center for Informatics in Wadern, Germany, September 11-16, 2011. Workshop participants from several countries came together to write the papers, which focus on various aspects of using DDI in the context of the Semantic Web.

Using RDF to Describe and Link Social Science Data to Related Resources on the Web: Leveraging the Data Documentation Initiative (DDI) Model

This paper looks at leveraging DDI to enable semantic linking of social science data to other data and related resources on the Web and is organized into five use cases: (1) Linking related publications; (2) Linking people and organizations; (3) Linking geography; (4) Linking related studies; (5) Linking to licenses.

Other Topics

These papers cover new and emerging themes related to DDI.

Exploring the Relationship Between DDI, SDMX and the Generic Statistical Business Process Model

This paper, presented at the Second Annual European DDI Users Group Meeting in Utrecht, Netherlands, in December 2010, investigates the similarities and degree of overlap among the DDI, SDMX, and GSBPM standards.

Representing and Utilizing DDI in Relational Databases

This paper, which resulted from a workship hosted by the Leibniz Institute for Educational Research and Educational Information (DIPF) and held in Frankfurt, Germany, on April 7-8, 2011, explores the use of relational databases to represent DDI XML. 

Communicating in Time and Space: How to Overcome Incompatible Frames of Reference of Producers and Users of Archival Data

This paper, written by Professor Bo Sundgren of Stockholm University, was the basis of the Keynote Address at the European DDI Users Group Meeting (EDDI) held December 5-6, 2011, at the Swedish National Data Service (SND) in Gothenburg, Sweden.

Developing a Model-Driven DDI Specification

This paper, an outcome of a 2012 Dagstuhl seminar on "DDI Moving Forward," captures the decisions and deliberations of the seminar participants on the approach to creating a new model-based standard.

A Qualitative Data Model for DDI

This paper, informed by key qualitative data use cases, presents a model describing qualitative data.
