The purpose of this review is to examine the process of transforming the EA XMI into the canonical XMI and from there to the various implementation syntaxes. This is being done as there were changes in this process between the last public review and the presentation of the final package to the Technical Committee for the purpose of preparing the product for a vote for publication.

The document documents at then the end of this page is are not part of the current publication package but provides production information you will need for your review. We are particularly interested in the following topics in relationship to the generation of multiple syntax representations of the DDI-CDI model:

Following is a segment of the email submitting DDI-CDI to the Technical Committee for review and preparation for a publication vote. It includes links to the materials you will need for review.

Since the first Candidate Release was submitted, the DDI-CDI specification has gone through further implementation and testing, including a pre-production implementation at UKDA of the variable descriptions and data structures (in both XML and RDF syntaxes), another proof-of-concept using the Process description portion of the specification in combination with DDI Lifecycle at the European Social Survey, combining social, environmental, and climate data as part of the EOSC Future "Climate Neutral and Smart Cities" project, and has further been implemented at Sikt (SPSS and Stata transformation to DDI-CDI) and at the workshop in Dagstuhl (a prototype CSV-to-DDI generator was developed, for use by the UN Statistical Division, as part of the development of the Cross Domain Interoperability Framework (CDIF) effort.
