NADDI 2013 Program Now Available

The program for the first annual North American Data Documentation Initiative (NADDI) Conference is now available at: http://www.ipsr.ku.edu/naddi/program.shtml
The NADDI Conference will take place on April 2 and 3 in Lawrence, Kansas and registration is now open. http://www.ipsr.ku.edu/naddi/registration.shtml.  Please register by March 5, 2013. A reduced registration rate is available for a limited number of graduate students.
The keynote speaker will be Dr. Jay Greenfield http://www.ipsr.ku.edu/naddi/JayGreenfield.shtml of Booz Allen Hamilton where he is the semantic architect for a DDI Lifecycle based metadata system that supports the National Children's Study (NCS).
DDI is an international data standard for the observation and measurement of human activity. Although primarily used by quantitative social scientists, an increasing number of scientists in other disciplines are embracing DDI to document and manage their data and metadata. More information about DDI is available at: http://www.ddialliance.org/
The conference will be informative, interesting, and educational. There will be presentations on the use of DDI in research programs and data repositories, developments with DDI and demonstrations of new DDI tools. The NADDI Conference is an opportunity for those using DDI and those interested in learning more about it to come together and learn from each other. Patterned after the successful European DDI conference (EDDI), the conference will of interest to both researchers and data professionals in the social sciences and other disciplines.
Following the conference, on April 4, 2013, there will be a full day of training on the use of DDI. More information about the training is available at: http://www.ipsr.ku.edu/naddi/training.shtml
Major funding for the conference has been provided by the Alfred P. Sloan Foundation. More information about the foundation is available here: http://www.sloan.org/ .
The conference is hosted and sponsored by the Institute for Policy & Social Research (http://www.ipsr.ku.edu ),  KU Libraries (http://lib.ku.edu/), the DDI Alliance (http://www.ddialliance.org/).

DDI Qualitative Working Group Meeting Held in Bergen

Following the working group meeting in Gothenburg in December 2011, a small group has been formed to work on defining a robust model for describing qualitative data, from data collection to archiving to re-use, convened by Arofan Gregory and Louise Corti.  At the Bergen meeting, held prior to EDDI12 meeting, progress was made to create a representative model, depicted by three class view diagrams (thanks to Larry Hoylel for his tireless work on this) plus detailed definitions of objects and their properties and relationships. The model and definitions will be available for external review in late January, so do watch this space.

DDI Moving to Model-Driven Specification

At its annual meeting in June 2012 the DDI Alliance approved the creation of a model-driven specification for DDI with bindings to expressions like XML and RDF. This next-generation specification will will make it easier to interact with other disciplines and other standards, to understand the specification, to develop and maintain it in a consistent and structured way, and to enable software development that is less dependent on specific DDI versions.


To begin work on the model, a workshop was held at Schloss Dastuhl in Wadern, Germany, in October 2012.

EDDI Conference Program Available

We are seeking presentations, talks, papers, posters on all things DDI:

  • Case Studies
  • Mature implementations
  • Early Implementations
  • Interplay of DDI with other standards or technologies
  • Projects in early phases in which DDI is under consideration

Call for Tools / DDI Tools Award

We invite developers and practitioners to participate in the first DDI Tools Competition and show the world what can be done for visualizing the content of DDI instances. The main goal of the DDI Tools Competition is to develop innovative applications that show DDI-based information to the end-user. Conceivable examples are (but not limited to): generators for smart codebooks in form of PDF or Microsoft Help files, parts of web information systems or portals, and stand-alone applications. The tools should be able to consume DDI Lifecycle (3.1) instances, and should be made available as Free Software (i.e. source code as Open Source). Further details on the competition and on sample instances will be announced on October 8. Please use the online submission system of the conference to submit an abstract on your tool until October 3, 2012. The deadline for submissions of the final program code is November 17, 2012.
