The Data Documentation Initiative (DDI) Alliance is pleased to announce the
first Public Review of DDI – Cross Domain Integration (DDI-CDI), a
specification aimed at helping implementers integrate data across domain
and institutional boundaries.

Although historically the DDI Alliance has produced specifications aimed at
the Social, Behavioral, and Economic (SBE) sciences, DDI-CDI is designed to
serve a broader audience, reflecting the need across many different domains
to exchange and reuse data which comes from outside the traditional range
of data sources. It is intended to be used as a stand-alone specification
for data integration in any domain or combination of domains and it can be
used in combination with existing DDI specifications (e.g., DDI-Codebook
and DDI-Lifecycle).

Reflecting this broader objective, CODATA sees great potential in DDI-CDI
as a contribution to the International Science Council-endorsed
<https://council.science/> 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.

DDI-CDI focuses on a uniform approach to describing a range of needed data
formats (traditional wide/rectangular data, long [event] data,
multi-dimensional data, and NoSQL/key-value data) which allows them to be
connected and understood to support transformation and processing for
integrated use. It is explicitly designed to work with many popular generic
technology standards such as PROV-O, BPMN, DCAT, SDMX, DataCube, SSN/SOSA
and Schema.org <http://schema.org/> to allow for easy integration into
systems which support them. DDI-CDI is aligned with other DDI
specifications (DDI-Codebook, DDI-Lifecycle) to support integration of
external data in systems which use DDI.

Review by experts both within and outside the SBE sciences will assist in
making sure that DDI-CDI is able to describe data and its provenance at a
detailed, machine-actionable level. This Public Review is intended not only
to critique the existing model and XML syntax representation, but also to
identify places where additional work is needed to better support research
and policy in the broadest possible set of domains.

Links to the specification and instructions for comment are found at
https://ddi-alliance.atlassian.net/wiki/x/IQBPMw. We are eager to obtain
feedback from the broadest possible audience on this specification. The
comment period is open until July 31, 2020, and we hope to hear from you.
To assist you in your review we recommend the following approach:

Read the Overview section of the DDI-CDI review page. This provides a guide
to what you will find in the download package. There are four documents
linked from the Overview section. Looking at these in the order presented
will provide you with information on the purpose, organization, use, and
structure of DDI-CDI. Depending on your areas of interest and expertise you
may be focusing on specific aspects of the package. These documents will
help guide you to the relevant material. If you have questions about the
package contents and how to review them, use the issue form or email option
to ask for clarification. Find these options through the link in the upper
right frame of the review page.

We will be conducting a series of webinars to introduce potential reviewers
to DDI-CDI. CODATA will support and collaborate on this series. Webinars
are being planned for core DDI stakeholders and users and then for a wider
range of domains and use cases, including: Earth sciences, life sciences,
engineering, physical sciences, SDGs and policy monitoring indicators,
discovery standards, process and provenance. If you are interested in
attending, please contact us by replying to this email.

Your feedback to DDI-CDI is appreciated.
