<p class="MsoNormal"><span lang="EN-US">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
a series of general introductory webinars have been held. Perhaps you already took part in one of them or would like to have a look at them?

About DDI-CDI</b><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">DDI-CDI is a model-driven specification that is designed to provide support for the wide number of use cases that use data from multiple sources and domains. It originates from the Social, Behavioral, and Economic (SBE)
sciences, but is designed to be applicable to data coming from any domain. Integrating data across domain and disciplinary boundaries requires a flexible mechanism for describing disparate data sources, and their provenance and processing. 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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Cross Domain (Data) Integration is particularly important for grand challenge research areas that necessarily combine data of many types.</span><a href="https://codata.org/"><span lang="EN-US"> CODATA</span></a><span lang="EN-US"> sees
great potential in<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">DDI-CDI as a contribution to the</span><a href="https://council.science/"><span lang="EN-US"> International Science Council</span></a><span lang="EN-US">-endorsed</span><a href="https://codata.org/initiatives/strategic-programme/decadal-programme/"><span lang="EN-US"> Decadal
Programme ‘Making Data Work for Cross-Domain Grand Challenges’</span></a><span lang="EN-US">. Consequently, CODATA through the Decadal Programme will partner with DDI in the public review process, assisting in getting feedback.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">DDI-CDI aims to be technology agnostic and to be adaptable to any platform or representation. At the moment the DDI-CDI specification is provided as a formal UML model and as an XML syntax representation of that model:
we are keen to adapt it to other technologies and representations, including RDF, JSON, Python etc.<o:p></o:p></span></p>
