Webinars Introducing DDI-CDI (Cross Domain Integration) to a Global Audience

Presentations and Recordings

Two webinars were held to introduce DDI-CDI to the global data community: one on 16 June 2020 at a time intended to be convenient for participants in the Western Hemisphere, one on 18 June for the Eastern Hemisphere.  The presentations and recordings are linked below.

The recording of the webinar on 16 June, is available below from Vimeo:

The recording of the webinar on 18 June, is available from the CODATA GoToWebinar Channel or below from Vimeo:




About the Webinars

The Data Documentation Initiative Alliance has recently announced the public review of their new specification, DDI – Cross Domain Integration (DDI-CDI). In order to introduce potential reviewers to the specification, webinars were held on Tuesday, 16 June 2020 at 14:00 UTC and on Thursday, 18 June at 07:00 UTC. The specification was introduced, followed by a discussion period, with each the webinar lasting for an hour. 

DDI-CDI is a model-driven specification that is designed to provide support for the wide range of data which are becoming increasingly significant for the Social, Behavioral, and Economic (SBE) sciences, but often come from new sources outside the SBE domain, and often use non-traditional data structures. Such unfamiliar data also demands increased information about provenance, especially the processes by which they were created. Based on the DDI 4/Moving Forward work, DDI-CDI is designed to meet these emerging needs for the integration of data in old and new forms, coming from a variety of domains.

Cross Domain (Data) Integration is particularly important for grand challenge research areas that necessarily combine data of many types and provenance, including infectious disease research, disaster risk reduction, resilient cities research, climate change mitigation and adaptation and so on. CODATA sees great potential in DDI-CDI as a contribution to the International Science Council-endorsed Decadal Programme ‘Making Data Work for Cross-Domain Grand Challenges’. Consequently, CODATA through the Decadal Programme will partner with DDI in the public review process, assisting in getting feedback on the specification from different domains and use cases.

The DDI-CDI specification is available both as a formal UML model and as an XML syntax representation of that model and is designed to align with both existing DDI specifications and other popular standards. Being model based, it is intended to support a wide range of technology platforms and tools. This webinar will help potential adopters provide critical feedback to make sure that it can meet these goals.
