[DDI-users] Public Review: DDI - Cross Domain Integration (DDI-CDI)

[Jared Lyle]

The DDI Alliance is pleased to announce the Public Review of DDI - Cross
Domain Integration (DDI-CDI), a specification aimed at helping implementers
integrate data across domain and institutional boundaries.  The new DDI-CDI
is an application of the model which emerged from many years of work on a
"next generation" DDI specification, known as "DDI 4."

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. DDI-CDI is aligned with other DDI specifications
(DDI-Codebook, DDI-Lifecycle) to support integration of external data in
systems which use DDI. 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 to allow for easy integration into systems which
support them.

DDI-CDI offers an extension to the suite of DDI work products which will
help those in the SBE domains and outside of them integrate the expanding
range of data required by today's research.

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 a broad community 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.

Your feedback to DDI-CDI is appreciated.
