Members selected for temporary working group to propose a restructuring of the Scientific Board

Dear DDI community,

I am pleased to announce the members of the temporary working group to propose a restructuring of the Scientific Board.  Members include:

  • Jane Fry (Carleton University and DDI Training Working Group co-chair)
  • Dan Gillman (U.S. Bureau of Labor Statistics)
  • Jon Johnson (CLOSER and DDI Technical Committee vice-chair)
  • Ron Nakao (Stanford)
  • Hilde Orton (NSD)
  • Nicolas Sauger (Sciences Po)
  • Wendy Thomas (Minnesota Population Center and DDI Technical Committee chair)
The goal is to restructure the Scientific Board so it is active and engaged throughout the year -- beyond the annual meeting -- and optimally functioning as the scientific and technical body of the Alliance.  Ingo Barkow, current vice chair of the Scientific Board, will chair the working group; Achim Wackerow, chair of the Scientific Board, and I will also participate.
 
Participants will engage in several conference calls and one in-person meeting.  Work will be completed in advance of the May 2020 annual meeting, when the finalized proposal will be discussed and voted on.  Thanks to all participants for their service.

DDI Lifecycle 3.3 specification available for final public review and comment

In the summer of 2018, DDI Lifecycle version 3.3 was made available for public review. Several important issues were identified as a result of that review. Those issues were thoroughly reviewed and addressed, and are now ready for final review at:

https://ddi-alliance.atlassian.net/wiki/spaces/DDI4/pages/794951754/DDI+Lifecycle+3.3+-+Final+Review

This page includes a link to the package containing the schemas and field level documentation. In addition, there are links to related content: Model documentation, High Level documentation, Implementation Guide, Examples, and a complete 3.2 to 3.3 change log with notes on requirements for transforming from version 3.2 to 3.3.

A brief review period for this revised DDI Lifecycle version 3.3 will take place Friday, January 25 through Friday, February 21, after which the Alliance will vote on the new specification.

Version 3.3 contains additional new coverage for the following:

  • Classification management (based on GSIM/Neuchatel)
  • Non-survey data collection (Measurements)
  • Sampling
  • Weighting
  • Questionnaire Design
  • Support for DDI as a Property Graph (properties on items and references)
  • Quality Statement improvements (useful for Eurostat reporting)

DDI Lifecycle version 3.3 also includes improvements in the types and organization of documentation for the specification. These changes allow for the publication of updates and additions as they occur rather than requiring the reissue of the specification itself. We welcome comments on the coverage and format of this documentation.

 

EDDI Conference Held in Tampere, Finland

EDDI 2019 was held at Tampere University and was jointly hosted by Statistics Finland and the Finnish Social Science Data Archive, who were celebrating their 20th anniversary.

With 89 participants, it was the largest EDDI since 2014, and also the largest ever turn out from the host country. Over half of the participants were from Scandinavia!  

Tutorials included: an introduction to DDI (utilizing material from the DDI Train-the-Trainers initiative), using paradata with DDI, going beyond a DDI codebook, and how a syntax representation of the DDI 4 UML model can be generated in any language.

There were two keynotes. Marja Rantala from Statistics Finland gave an interesting and insightful talk on challenges in interoperability drawing on her extensive experience in aligning Nordic geography. The second keynote was from Damien Lecarpentier speaking about the challenges of building the European Open Science Cloud, which is bringing together a coherent infrastructure which it is hoped will foster cross disciplinary data sharing.

One theme of the program was how DDI is now embedded in many key infrastructures in Europe -- beyond data archives. Examples included the adoption of DDI controlled vocabularies in CESSDA and how they are key in solving the challenges of multilingualism,  as well as the maturing of DDI-Lifecycle to support questionnaire development and longitudinal data management. Other presentations highlighted adoption of DDI in National Statistical offices as GSIM progresses from modelling into implementation.

The poster session is always a highlight of EDDI, and this year was no exception. Software and tools both in development and in maturity were demonstrated focusing on questionnaires and grappling with legacy data. Poster presentations showcased international developments, including three from Japanese participants!  More information on presentations and posters are available from https://zenodo.org/communities/eddi19/.

The next EDDI conference will be in Paris, hosted by SciencePo, on the 1st & 2nd of December 2020.

Seeking nominations for temporary working group to propose a restructuring of the DDI Scientific Board

The DDI Alliance would like to improve the structure and organization of the Scientific Board, which is the scientific and technical body of the Alliance.  At the 2019 Annual Meeting of the Scientific Board, a temporary working group was approved to propose a restructuring and to draft changes to the Alliance Bylaws.  This work is to be completed in advance of the May 2020 annual meeting, when the finalized proposal will be discussed and voted on.  Participation in the temporary working group will involve several conference calls and one in-person meeting.  The temporary working group will be chaired by Ingo Barkow, current Vice Chair of the Scientific Board.  

We are seeking 4-5 participants for the working group.  We are especially interested in a diverse representation, including individuals new to DDI.  All member institutions may nominate an individual to participate on the temporary working group.  To submit nominations, please email names to secretariat@ddialliance.org by 13 December.  The DDI Executive Board will make the final selection of working group members.

A Birds-of-a-Feather session at the December 3-4 European DDI (EDDI) conference will include discussion about the temporary working group.  Interested members attending EDDI are invited to participate in the session.
