Public Review of DDI 3.3


Date: Aug 7, 2018


The DDI Alliance (http://www.ddialliance.org/) is pleased to announce the Public Review of DDI 3.3. This version of the DDI specification includes important updates and new content, including:
 
  • Classification management (based on GSIM/Neuchatel)
  • Non-survey data collection (Measurements)
  • Sampling
  • Weighting
  • Questionnaire Design
  • Support for DDI as a Property Graph
  • Quality Statement improvements (useful for Eurostat reporting)
Additionally, DDI 3.3 has a formal model now, so a detailed changelog can be generated between DDI 3.2 and 3.3.

We are eager to obtain feedback from the DDI and RDF communities on this vocabulary. The comment period is open until September 21, 2018, and we hope to hear from you!
