The DDI Alliance, CODATA and other partners are organising three workshops in September.  These will be hybrid in format, using the traditional Dagstuhl location in conjunction with other remote locations and participants.  The topics of the workshops are as follows:

• Further Development of the DDI Cross Domain Integration Model for FAIR Data Sharing across Discipline and Domain Boundaries, Schloss Dagstuhl – Leibniz Center for Informatics, Wadern, Germany, September 20-24, 2021
• Interoperability for Cross-Domain Research: Use Cases for Metadata Standards, Schloss Dagstuhl – Leibniz Center for Informatics, Wadern, Germany, September 27 to October 1, 2021
• Interoperability for Cross-Domain Research: FAIR Vocabularies, Canberra, Melbourne, and other sites in Australia, September 27 to October 1, 2021

The workshop on DDI-CDI will inform on a technical level the subsequent workshop on use cases for metadata standards.

The two workshops on ‘Interoperability for Cross-Domain Research’ build on the outcomes of two previous Dagstuhl Workshops in 2018 and 2019 on the alignment of standards and technologies for cross-domain data combination. These two workshops, taking place in different time zones will collaborate at specific times in the day.

The ideas for all workshops were developed within the cooperation of CODATA and DDI Alliance by the long-time organizing team Simon Cox, Arofan Gregory, Simon Hodson, Steven McEachern, and Joachim Wackerow. Additional organizers contribute to specific workshops: Rowan Brownlee, Hilde Orten, and Lesley Wyborn.

Participation is by invitation only.

DDI member representatives voted in July 2021 to elect four members to the DDI Executive Board.  This followed a call for nominations in April and discussion of the candidates at the June annual Meeting of Members.  

The DDI Executive Board is  composed of seven voting members: six At-Large members elected by the Designated Member Representatives and one member appointed by the Host Insitution.  Members serve for a term of four years. The Executive Board is responsible for managing the operations of the Alliance, including setting overall policy and budget.

Fifteen of the 28 voting eligible DDI member representatives participated in the election.  According to the Alliance Bylaws, the election is decided on the basis of those candidates getting the most votes.

The election results (number of votes are indicated in parentheses):

• Cory Chobanik (14)
• Steve McEachern (14)
• Barry Radler (13)
• Cathy Fitch (12)

I want to thank Barry, Cathy, Cory, and Steve for accepting the nominations and for their service on the Board.  Barry, Cathy, and Steve are incumbent members of the Board.  Cory is a new member.  Their biosketches and position statements (when provided) are listed below.

I also want to sincerely thank Dana Müller, who served on the Board from 2017-2021.  Dana's commitment and insights were invaluable.

Sincerely,
Jared

Position Statement

For the better part of two decades I have been using DDI products to document a complex multi- disciplinary longitudinal study that has generated an ever-growing body of popular data products. As such I have a vested interest in the DDI Alliance responsibly developing, managing, and promoting the suite of DDI standards and products. I hope to advance those interests by serving on the DDI Alliance Executive Board for another term.

This Webinar will explain how different DDI products can help to support the implementation of the FAIR principles (guidelines to improve the Findability, Accessibility, Interoperability, and Reuse of digital assets).

CODATA (the Committee on Data of the International Science Council) recently completed a European Open Science Cloud co-creation project which explored the potential uses and applications of the draft Data Documentation Initiative Cross-Domain Integration (DDI-CDI) specification for EOSC.  The main output was a substantial report The Role of DDI-CDI in EOSC: Possible Uses and Applications which explores the challenges faced by EOSC and discusses a number of use cases/examples of the role that DDI-CDI can play.

Main report: The Role of DDI-CDI in EOSC: Possible Uses and Applications https://doi.org/10.5281/zenodo.4707263

The report was produced in close consultation with members of the DDI Alliance that developed the specification.  A wide range of experts participated in workshops and intensive meetings, as detailed in the activity report produced for the EOSC Secretariat.

Documentation on DDI-CDI is available below.  The DDI Alliance aim to publish the production release in June/July 2021.

Report Launch Workshop, 2 June

The report will be launched at a virtual workshop to be held at 13:00-15:00 UTC on Weds 2 June.  This workshop will summarise the key findings and recommendations of the report; discuss the examples/case studies and how they may be further explored and tested; and identify next steps for trial implementations.  The agenda and registration for the launch workshop will be announced in the near future.  In the meantime, please save the date!

The Role of DDI-CDI in EOSC: Possible Uses and Applications

This report looks at the potential use of the Data Documentation Initiative Cross-Domain Integration (DDI-CDI) specification to the data-sharing requirements faced by EOSC. By analyzing real-world projects and implementations, and through discussion with those responsible for related metadata and infrastructure specifications, the potential role played by the DDI-CDI model in the overall EOSC system is envisioned, and recommendations made for how to realize the identified opportunities for its use.

The challenges faced by EOSC can be broken into two main areas:

– Problems of Scale: The volume of data is growing exponentially and is coming from a wider range of sources. At the same time, the FAIR principles require an increased amount of metadata, especially when it comes to interoperability and reuse of that data. Current manual approaches are proving to be unsustainable. The automation of metadata collection – that is, harvesting metadata programmatically from systems which produce, manage, disseminate, and use data – offers a possible solution, but the necessary framework for such activities is not in place. Standard models and encoding for such metadata (a “lingua franca”) must be established for large-scale capture and exchange of metadata.

– Problems of Cross-Domain Use: In order for data to be shared across domain and institutional boundaries, it must be understood by its users at all levels. While increasing attention is paid to the semantic mapping of concepts across domains, there are other critical needs for such data sharing. Disparate data structures must be accommodated, based on the tools and formats used in specific domains, and the means of data collection and processing – the provenance of the data – must be understood. Use of specific domain models and vocabularies must be known, and they must be accessible in a machine-actionable form. Reusable crosswalks between domains are needed. All of these requirements point to the need for more granular metadata, so that data can be successfully re-arranged to be suitable for use outside its domain of origin. The path of a single observation, as it is reused and further processed, should be knowable.

DDI-CDI will not address all of these concerns; no single standard or technology will provide a complete answer. It has, however, been designed to fill important gaps in the needed range of standards, models, and technologies to meet these challenges. On the basis of an intensive series, of meetings, conference sessions, workshops and other discussions with a range of different groups, this report looks at use cases and the emerging FAIR ecosystem to understand the potential application of DDI-CDI, and the role it could play within a broader frame. The approach being taken by EOSC—as described in the EOSC Interoperability Framework and in other activities—is then assessed to show specifically where DDI-CDI would fit. Recommendations for further work are then made on that basis.

Specific implementation examples include a data integration using climate data, energy consumption data, and consumer questionnaire responses; an example of how a repository could facilitate automated capture of metadata, based on the Dataverse platform; a data integration example from the European Social Survey Multi-Level application; and an exploration of processing, provenance, and cross-domain requirements as seen in the ALPHA Network and INSPIRE applications for the integration of population and clinical data. An analysis of how DDI-CDI could be used in combination with DCAT is presented, and the role which DDI-CDI could play within the emerging FAIR ecosystem, in relation to FAIR Implementation Profiles, FAIR Data Points, and FAIR Digital Objects, is examined. Finally, the way in which DDI-CDI could be integrated into the emerging EOSC infrastructure is considered in light of the EOSC Interoperability Framework and the FAIRsFAIR vision of integrated metadata catalogues.

DDI-CDI offers a new type of specification which could help to realize the capture, interchange, and use of metadata throughout the EOSC data-sharing infrastructure, and could do so in ways which are scalable and machine-actionable. It operates at the needed level of granularity and would work to heighten the utility of semantic mapping and approaches to the full utilization of data. Our recommendations identify several concrete areas where this application of the model should be further explored.
