Administrative Data Group

Charge: DDI arose as a documentation standard for survey data. The Administrative Data Group will explore ways to enhance the DDI specification to document administrative data optimally.

Timetable:

  • Stage 1: Survey the different ways administrative data is documented in different organizations.
  • Stage 2: Summarize the special requirements of administrative data.
  • Stage 3: Review the DDI content with respect to data collection and administrative data.
  • Stage 4: Compare the requirements of administrative data with the capabilities of DDI.
  • Stage 5: Create proposals for a modification of the DDI standard.

First results will be presented at the DDI-expert meeting in summer 2012.

Members: The group is currently under construction. New members are welcomed. Please contact David Schiller, Institute for Employment Research, Germany (Chair)

Experimental Data Working Group

Charge: This Group will explore and recommend ways to enhance the DDI specification to better document experimental data, such as randomized controlled trials.  The group will develop requirements for new/changed elements and attributes in the specification.

Timeline: The group will meet virtually and by phone during the coming year, with the goal of presenting a proposal for changes to the specification to the Technical Committee before the next DDI Alliance Expert Committee meeting in June 2014.

Membership opportunity: new members are welcomed.  Please contact Kate McNeill for more information.

Chair: Katherine McNeill, MIT

Members:

  • Limor Peer, Yale University
  • Wolfgang Zenk-Moeltgen, GESIS-Leibniz Institute for the Social Sciences 

Qualitative Data Model Working Group

Charge: To develop a robust XML-based schema for qualitative data exchange (compliant with DDI) and encourage tools development based upon these needs.

Timetable: Start January 2010 -- First meeting, 19 April 2010; Gothenburg working meeting December 2011; Bergen working meeting November 2012

Progress: Draft QuDex schema produced outside of remit of the group in 2008. The group have built on this schema and evaluated its relationship to DDI. Three class views for qualitative data collection, archiving, and re-use have been modelled and an object definitions document created.

Convenor: Arofan Gregory, Metadata Technology
Chair: Louise Corti, UK Data Archive
Architects: Larry Hoyle, University of Kansas, and Agustina Martinez, Liverpool John Moores University

Group Report, 2012-2013

In 2013 the group released a white paper describing the model: A Qualitative Data Model for DDI.

RDF Vocabularies Working Group

Charge: To develop RDF vocabularies for efficient use of DDI metadata in the contect of the Semantic Web/Linked Data.

Work is under way on two RDF vocabularies, the DDI-RDF Discovery vocabulary for publishing metadata about datasets into the Web of Linked Data, and XKOS, an RDF vocabulary for describing statistical classifications, which is an extension of the popular SKOS vocabulary.

The work on both vocabularies 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 (http://www.dagstuhl.de/11372). This work has been continued at these three meetings: follow-up working meeting (Discovery vocabulary) at the 3rd Annual European DDI Users Group Meeting (EDDI11) in Gothenburg, Sweden, in December 2011 (http://www.iza.org/eddi11); second workshop on "Semantic Statistics for Social, Behavioural, and Economic Sciences: Leveraging the DDI Model for the Linked Data Web" at Schloss Dagstuhl in October 2012 (http://www.dagstuhl.de/12422); and a follow-up meeting (Discovery only) at GESIS-Leibniz Institute for the Social Sciences in Mannheim, Germany, in February 2013.
