DDI Training Materials -- Now Available in French
Submitted by lyle on Tue, 2024-01-30 15:16
To meet the training needs of the French-speaking community, the DDI Training Working Group has translated several training materials that are now available on the DDI Alliance website.
Translating DDI documentation training materials
The Centre for Sociopolitical Data (CDSP) has been participating for several years in the coordination of the DDI Training Working Group, whose mission is to promote the DDI data documentation standard and provide training in its use.
Initiated by the two co-chairs of the TWG (Alina Danciu and Hayley Mills), the coordination of this project was ensured by Lucie Marie (CDSP) in collaboration with other engineers from the CDSP and with the engineers from IR* Progedo.
The translations, validated by the DDI Alliance Scientific Advisory Board, are now available on the DDI Alliance website and archived on Zenodo .

DDI Lifecycle - 4.0 beta announcement
Submitted by lyle on Fri, 2023-12-22 15:52
Hello DDI Community,
The Technical Committee is happy to announce the availability of a beta version of DDI Lifecycle 4.0.
DDI Lifecycle 4.0 is managed using a Model First development approach. Content additions and changes are added to the model and the serialization formats are automatically generated. The metadata content of DDI 3.3 has been converted into the new 4.0 model.
The ddi-lifecycle-4.0-beta.1.zip package includes:
- schema.xsd - XML Schema
- jsonSchema.json - JSON Schema
- ddi4.xmi - OMG's UML XMI 2.5
- ddi4.owl - RDF OWL (closed with restrictions)
- ddi4.owl.ttl - RDF OWL (open)
- ddi4.shex - ShEx
- ddi4.shacl- SHACL
Other formats are also available but are not included in the official release. The beta package is available at: https://github.com/
The documentation for DDI Lifecycle 4.0 is also autogenerated from the model, and can be viewed at: https://ddialliance.
We are looking for feedback on the community's preference between the different OWL serializations and general comments about the XML and JSON. One version of the OWL models restrictions, the other is open and uses RDF shape languages to define rules. Ordering of lists in the OWL is handled using normal predicate relations combined with the addition of enumerable slots with index positions to keep the vocabularies in OWL-DL, we would like to hear the community's feedback on this approach to ordering as shown in the Sequence item type.
You can provide questions and comments back using the github issues with a free github account at: https://github.com/
Thank you,
DDI Technical Committee
