We have created an export of Smart Data Models in DTDL format. You’ll see them in the root directory named schemaDTDL.json.
A bit more than 500 models have got it because we are in the process of a final complete mapping between the possibilities of JSON schema and DTDL.
This is the first version for testing purposes and they are not meant to be ready for production. Anyhow, we welcome any feedback on them.
