<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The DDI Alliance released a prototype of DDI 4. DDI 4 is a large UML model library for describing research and other data. Subsets of the library--called views--are
provided for specific user perspectives. Encodings in other technologies, XML Schema and OWL/RDF, are available as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">DDI 4 has potential as a metadata standard for cross-domain research data. Large parts of DDI 4 are independent from the social science domain. Especially in
the areas of data description, conceptual, and workflows (for process description), DDI 4 will be useful for a cross-domain approach. The DDI 4 data description is based on two powerful techniques: first, the datum-based approach which enables the description
of data in many forms (also data lakes and legacy forms); second, the variable cascade which links conceptual definitions down to the instance variable.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The current DDI 4 is a prototype release. We would like to get comments on this early release from the broader community. The comments will enable further focused
development work on DDI 4.<o:p></o:p></span></p>

the data produced by surveys and other observational methods in the social, behavioral, economic, and health sciences. They can document and manage different stages in the research data lifecycle, such as conceptualization, collection, processing, distribution,
discovery, and archiving.<o:p></o:p></span></p>

<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:black">We’re happy to announce the prototype release of DDI 4. This preliminary version is not intended for production but provides an opportunity
to test and provide feedback on how the DDI 4 model describes and documents some basic research material, such as a dataset, an instrument, and a codebook. </span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p style="margin:0cm;margin-bottom:.0001pt"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:black">DDI 4 is based on an information model that can be expressed in different technologies, including standard RDF vocabularies and XML structures.
This form of model-based standard is a best practice in the standardization world, and several other domains have used this approach for years to structure their domain-specific standards. The development of DDI 4 will enable the standard to stay abreast of
current technological changes and guarantee alignment across different technology implementations. More details about the history and origin of DDI 4 can be found on the “Work Products of the DDI Alliance”
