There is a command group 'az_dt_model'. This group of commands could 'manage dtdl models and definitions on a digital twins instance'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_dt_model_list'.The syntax is: az dt model list --dt-name
                 [--def {false, true}]
                 [--dependencies-for]
                 [--resource-group]. The 1th example of the child command would be to use it to 'list model metadata', the syntax is: az dt model list -n {instance_or_hostname}. The 2th example of the child command would be to use it to 'list model definitions', the syntax is: az dt model list -n {instance_or_hostname} --definition. The 3th example of the child command would be to use it to 'list dependencies of particular pre existing model s   space separate dtmi values', the syntax is: az dt model list -n {instance_or_hostname} --dependencies-for {model_id0} {model_id1}. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name or hostname. if an instance name is provided, the user subscription is first queried for the target instance to retrieve the hostname. if a hostname is provided, the subscription query is skipped and the provided value is used for subsequent interaction.. The parameter '--def --definition' is optional. the operation will retrieve the model definition.. The parameter '--dependencies-for' is optional. the set of models which will have their dependencies retrieved. if omitted, all models are retrieved. format is a whitespace separated list.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`..
