European DDI Conference 2021: Training Fair

The DDI Training Group organized a series of tutorials around the 2021 European DDI Users Conference. This included a general overview of the DDI standards on Friday 26 November, followed by a series of more detailed tutorials and a session describing the software tools and services available for implementing DDI, all on Monday 29 November.  A short description of each session is available here, along with recordings and presentations.

Track 1: Discovering DDI

This track provides a general overview of all of the DDI specifications and shows how DDI fits into the overall frame of FAIR data sharing, intended for newcomers who may want to learn what DDI is without diving into the details. The programme featured a number of speakers from the DDI Alliance and member organizations, including Jane Fry, Barry Radler, Jared Lyle, Arofan Gregory, and Simon Hodson.

Track 2, parallel session A: DDI Codebook tutorial

DDI Codebook is a metadata specification for providing detailed, machine-actionable and human-readable metadata about individual studies and their data files in an XML format. Instructors are Jane Fry of Carleton University and Adrian Dusa of the University of Bucharest, who will introduce you to this popular metadata standard.

Track 2, parallel session B: DDI Lifecycle tutorial

DDI Lifecycle addresses the needs of metadata management not only for archives and data disseminators, but also throughout the data lifecycle, from data collection and survey design through the end stages. It is also a useful tool for understanding how related data sets fit together, whether as a longitudinal or repeat cross-sectional effort, or through ad-hoc comparison and harmonization. A range of topics will cover a broad description of the specification, as well as providing focus on specific aspects of the standard for metadata and data management. Presenters include Wendy Thomas, Hayley Mills, Kaia Kulla, and Benjamin Beuster.

Track 2, parallel session C: DDI Cross Domain Integration (DDI-CDI) tutorial

DDI-CDI is a forthcoming standard which is intended to complement other metadata specifications – notably DDI Codebook and DDI Lifecycle – by making it possible to share and reuse data across domain boundaries and within and between research infrastructures. To do this, it uses a datum-centric approach to describing the structures of a wide range of data sets, including long, wide, multi-dimensional, and key-value types. Presenters are Dan Gillman and Arofan Gregory.

Track 3: DDI Tools and Services

This session provided an overview of many of the tools and service providers available to those who are interested in actively implementing DDI. Each presenter covered the tools and/or services which they provide in a short format, including product demos. The intention is to help users understand what tools and services exist, and who they should talk to in order to learn more.

Presentations/presenters included:

  • Colectica (Dan Smith, Jeremy Ivreson)
  • Metadata Technology North America (Pascal Heus, Andrew DeCarlo)
  • Kuha 2 (Toni Sissala, Finnish Data Archive)
  • DDI with R (Adrian Dusa): presentation slides
  • CLOSER Archivist (Hayley Mills)
  • Dataverse (Alina Danciu; Geneviève Michaud; Jim Myers; Baptiste Rouxel; Tom Villet): presentation slides
