Joachim (Achim) Wackerow, current member of the DDI Scientific Board, is retiring from GESIS at the end of February and will no longer be able to serve as an official member on the Scientific Board. Achim's term runs through June 2023. According to the DDI Bylaws, "Any member vacancy will be filled by election as soon as possible and that member will begin serving when elected for the remainder of the vacating member's term."
The Scientific Board is seeking nominations to fill Achim's vacancy. Representatives from Members and Associate Members of the Alliance are eligible to serve as elected members of the Scientific Board. If you are interested in serving, or know of someone else who would make a good candidate, please email me (firstname.lastname@example.org) by 28 February 2022. We will hold an election in March to fill the vacancy.
The Scientific Board is the scientific and technical body of the Alliance and represents the Scientific Community. The purposes of the Scientific Board are to:
- Provide direction and coordination in the development of the substantive content of the DDI standards and other work products of the Alliance by its sub-committees and working groups within the context of the Alliance Strategic Plan.
- Implement the scientific work plan agreed at the Annual Meeting of the Scientific Community.

DDI Standards and Metadata Featured in U.S. National Academies Report, "Transparency in Statistical Information"
The Committee on National Statistics under the U.S. Academy of Sciences, Engineering, and Medicine released a report on November 18, 2021 from the Panel on Transparency and Reproducibility in Federal Statistics called Transparency in Statistical Information for the National Center for Science and Engineering Statistics and All Federal Statistical Agencies (Report). You can download a copy for free by following the link. The panel included several people familiar to the DDI community.
The focus of the report is on transparency of federal statistics, where transparency is defined in the report as follows:
Transparency is the provision of sufficiently detailed documentation of all the processes of producing official estimates. The goal of transparency is to enable consumers of federal statistics to accurately understand and evaluate how estimates are generated.
The emphasis on documentation, understanding, and evaluation should be familiar to all who use the Data Documentation Initiative (DDI) metadata standards. This emphasis is about metadata.
The Report is divided into 7 chapters and 2 substantive appendices, with Chapter 5 devoted to metadata, systems, and standards. Several of the standards described are DDI-Codebook, DDI-Lifecycle, and the soon to be released DDI-CDI (Cross Domain Integration). SDTL, XKOS, and Controlled Vocabularies are briefly described, too. Descriptions of other standards, such as SDMX, DCAT, PROV, GSIM, and GSBPM are included and divided between Chapter 5 and Appendix A. In Appendix B, the case for how transparency can be achieved through the use of and conformance to standards is presented.
Every chapter deals with a particular aspect of transparency, and for many in the DDI community, Chapters 2 and 3 will be interesting, as archiving is discussed. Each Chapter includes a short set of recommendations for the federal statistical agencies, and the ones listed here include text about the need among the agencies to adopt standards and manage metadata. Excerpts from each follow:
3.1 "The metadata that accompany such data should also be preserved using broadly accepted metadata standards appropriate to the data at hand."
5.1 "The Interagency Council on Statistical Policy (ICSP) should develop and implement a multi-agency pilot project to explore and evaluate employing existing metadata standards and tools to accomplish data sharing, data access, and data reuse."
5.2 "The ICSP should: (1) prioritize and emphasize the importance and benefits of federal statistical agency staff engaging in international metadata standards and tool development, and (2) organize a discussion among statistical agencies that leads to an effective, coordinated, and accountable approach for staff in agencies that produce federal statistics to contribute to international metadata standards and tool development."
The Report provides an opportunity for the DDI Alliance to position itself as the source of many of the metadata standards needed by the federal statistical agencies to achieve transparency. The expertise that many representatives of member organizations in the Alliance can bring to discussions is vital to furthering the adoption of DDI. Communication among the Alliance, the ICSP, and the agencies should begin soon.

The DDI Alliance hosts several mailing lists using Mailman software, including the ddi-users mailing list we use to communicate with the entire DDI community.
We are now planning to transfer mailing list hosting from Mailman to Google Groups. We expect this transfer to improve stability and usability. The transfer is scheduled for the week of 1 February 2022.
After the transfer, users should not notice a large difference in messages sent on the lists. Existing mailing list subscribers will remain as list subscribers and will continue to be able to send and receive messages. The primary difference will be that starting February, messages sent to DDI mailing lists will be stored in a Google Group rather than on a Mailman archive. Mailman archives will be retained in their current format for the time being.
For mailing lists with no activity since 2019, we will shut down the list but retain the Mailman archives. Any users on those retired lists not already subscribed to ddi-users will be subscribed.
Please feel free to contact the Secretariat with any questions. We will be emailing each list as we progress through the transfer to Google Groups.

The DDI Alliance Scientific Board has approved the establishment of a "simple liaison" relationship with the World Wide Web Consortium (W3C) to coordinate activities in the field of data description, especially around specification development. The goal of a simple liaison is for both parties to gain a better understanding of their respective activities and look for opportunities to work together. Most often, W3C establishes simple liaisons with peer organizations, other standards bodies, or any other non-profit entity that may wish to build consensus around an emerging Web technology.
The W3C contact is Pierre-Antoine Champin, W3C fellow and coauthor of JSON-LD. The DDI Alliance contact is Joachim Wackerow, DDI Scientific Board member and collaborator with W3C experts in the context of the Schloss Dagstuhl – Leibniz Center for Informatics workshops on DDI and metadata. Since 2011, twelve experts involved in W3C activities (six of them are members of the W3C DXWG) have participated in Dagstuhl workshops on DDI and metadata.
The main W3C activity affected by the liaison is the Dataset Exchange Working Group (DXWG), which created the Data Catalog Vocabulary (DCAT). Data description specifications are increasingly used in combination with other specifications, especially in the semantic web. An important example is the combination of DCAT with a specification that describes more granular elements (e.g. variables); DDI-Cross Domain Integration (DDI-CDI) is a candidate as a domain-independent specification. Other DDI-relevant W3C specifications include: RDF Data Cube Vocabulary, CSV on the Web, Data Catalog Vocabulary, and Provenance Ontology (PROV-O).
The Chair and Vice Chair serve two year terms. In addition to leading the Executive Board, which is the policymaking and oversight body of the DDI Alliance, the Chair and Vice Chair also lead the Annual Meeting of the DDI Membership Representatives.
Special thanks to Steve McEachern, Australia Data Archive (ADA), who served the previous three consecutive terms as Chair of the Executive Board.
