If model A references another model in its interface definition, e.g. in 'extends' or in schema of a component, than the referenced model file will only be found, if the model name equals the file name.

Working (with model 'dtmi:digitaltwins:GeoSPARQL:SpatialObject;1' defined in file 'SpatialObject.json'

        }
    ],

This also means that using ModelUploader with models that have the same name but a different namespace doesn't work.

Hi there,

I am facing an issue trying to execute the command for the OWLTODTLD converter:

I have tried the example command on my Mac through VisualStudio terminal and Mac terminal : p@@@@@@-MBP opendigitaltwins-tools % ./OWL2DTDL -u https://w3id.org/rec/full/3.3/ -i ./RecIgnoredNames.csv -o /Users/pzerva/Desktop/DTDL/
and I get : zsh: permission denied: ./OWL2DTDL

although I seem to have both r and w access to the files/folders of OWL2DTDL.

Also another question is that in the example execution a URI needs to be provided for the ontology model - what if I have some local ontologies files/models I want to convert in DTDL - is it possible to convert those and what commands I can use?

In addition is there a converter from JSON-LD twins and models to DTDL ?

Multilingual labels or comments are not properly combined in the output DTDL JSON-LD.

The following

<rdfs:Datatype rdf:about="https://data.arcadis.com/test"/>
<owl:DatatypeProperty rdf:about="https://data.arcadis.com/test">
    <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#string"/>
</owl:DatatypeProperty>
<rdf:Description rdf:about="https://data.arcadis.com/test">
    <rdfs:label xml:lang="en">Test</rdfs:label>
    <rdfs:label xml:lang="nl">Test-NL</rdfs:label>
    <rdfs:label xml:lang="fr">Test-FR</rdfs:label>
    <rdfs:comment xml:lang="en">comment</rdfs:comment>
    <rdfs:comment xml:lang="nl">Comment-NL</rdfs:comment>
    <rdfs:comment xml:lang="fr">Comment-FR</rdfs:comment>
</rdf:Description>

generates the following output DTDL

{
  "@type": "Property",
  "description": {
    "en": "comment"
  },
  "dtmi:dtdl:property:description;2": [
    {
      "@language": "nl",
      "@value": "Comment-NL"
    },
    {
      "@language": "fr",
      "@value": "Comment-FR"
    }
  ],
  "displayName": {
    "en": "Test"
  },
  "dtmi:dtdl:property:displayName;2": [
    {
      "@language": "nl",
      "@value": "Test-NL"
    },
    {
      "@language": "fr",
      "@value": "Test-FR"
    }
  ],
  "name": "test",
  "schema": "string",
  "writable": true
}

What's the recommended option to upload models to ADT?

az dt model create seems an overlap with the UploadModels tool in this repo.

Hi, I've followed the instructions to the T with two separate subscriptions/accounts. I get the same error upon authenticating:

AADSTS650057: Invalid resource. The client has requested access to a resource which is not listed in the requested permissions in the client's application registration. Client app ID: 7fe23b3c-ecb6-xxxxx-yyyyy-52a41bc5b4bb(mxyxadt). Resource value from request: https://digitaltwins.azure.net. Resource app ID: 0b07f429-9f4b-xxxxx-yyyyy-cc5e8e80c8b0. List of valid resources from app registration: .

"clientId": "7fe23b3c-ecb6-yyyy-yyyy-52a41bc5b4bb",
"instanceUrl": "https://mxyxadt.api.xxx.digitaltwins.azure.net"
}

Any ideas why?

I don't think it is related, but I am using the new system-assigned identity feature in ADT. Should I not?
"A system-assigned managed identity enables Azure resources to authenticate to cloud services (e.g. Azure Key Vault) without storing credentials in code. Once enabled, all necessary permissions can be granted via Azure role-based-access-control. The lifecycle of this type of managed identity is tied to the lifecycle of this resource.Learn more."

Also, my AAD is not a "premium level" plan.

Thanks!

I have converted the Owl2DTDL to .exe in visual studio but nothing happens when I try to run .exe. Can you include a tutorial? Or provide a link.
