Submitted by lyle on Tue, 2024-11-05 14:03

The Technical Committee is happy to announce the availability of the second beta version of DDI Lifecycle 4.0.

https://github.com/ddialliance/ddimodel/releases/tag/v4.0-beta.2

We continue to look for feedback on the community's preference between the different OWL serializations and general comments about the XML and JSON. Users can provide questions and comments to the TC using github issues with a free github account at:

https://github.com/ddialliance/ddimodel/issues

Comments on this Beta 2.0 are requested by December 5th.

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. Issues raised during the first beta version review have been addressed.

The ddi-lifecycle-4.0-beta.2.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 2 package is available at: https://github.com/ddialliance/ddimodel/releases

The documentation for DDI Lifecycle 4.0 is also auto-generated in real time from the model, and can be viewed at: https://docs.ddialliance.org/DDI-Lifecycle/dev/model/

What's Changed

• Add Ordered attribute to properties which were implicitly ordered in the model

• Check cardinalities for choices from DDI to cogs conversion

• Upload development version builds to docs.ddialliance.org automatically

• Missing 3.3 elements with extension base Reference (In Person TC meeting activity)
