I try to adapt a module driver based on 7.9 **AbstractTagDriver**  
Package com.inductiveautomation.opcua has gone in Ignition 8.0.  
What are the substitute for :

com.inductiveautomation.opcua.types.NodeId  
com.inductiveautomation.opcua.types.StatusCode  
com.inductiveautomation.opcua.UAException  
com.inductiveautomation.opcua.types.\*

com.inductiveautomation.xopc.driver.api.tags  
and com.inductiveautomation.xopc.driver.api.configuration.DeviceSettingsRecord

Everything under `com.inductiveautomation.opcua` has a counterpart somewhere in `org.eclipse.milo.opcua` except the old `DataType`, which is `BuiltinDataType` in Milo.

`com.inductiveautomation.xopc.driver.api.tags` still exists.

`DeviceSettingsRecord` is at `com.inductiveautomation.ignition.gateway.opcua.server.api`

Delete the unresolved imports and then place your cursor on a class that’s missing an import and hit option/alt+Enter in IntelliJ and it will usually find and suggest the new import.

Thanks @Kevin.Herron, it's indeed simpler when we delete the unused import !

How to get BuiltinDataType from DataValue ????

```
public VariantDriverTag(String address, Object localValue, StatusCode statusCode) {
    this.localAddress = address;
    try {
        if (localValue == null){
            // crée un dataValue de type variant avec valeur null
            this.dataValue = new DataValue(statusCode);
            this.dataType = BuiltinDataType.Int64;
        }else {
            this.dataValue = new DataValue(new Variant(localValue),
                    statusCode,
                    new DateTime(),
                    new DateTime());
            this.dataType = dataValue.getValue().getType(); <=== 
            this.typeIndetermine = false;
            logger.info("construtor VariantDriverTag : address={},dataType={}",address,this.dataType);
        }
    } catch (UAException e) {
        logger.error(e.getMessage());
    }
}

```

As long as the `DataValue` isn’t holding a null value you can get the class of the underlying value and try `BuiltinDataType.fromBackingClass()`.

Eclipse is similar. But I find it convenient to use ctrl-shift-O to "Organize Imports" for the whole file at once. It rarely gets it wrong. (-:

Can you please give me a hint how to replace the NodeBuilders (com.inductiveautomation.opcua.nodes.builders.NodeBuilder, ObjectNodeBuilder, VariableNodeBuilder)?  
I found the VariableTypeManager.VariableNodeConstructor interface but have no idea how to get an actual instance of it.  
Is there a javadoc for milo somewhere? The source on github seems to have verly limited comments.

The [ExampleNamespace](https://github.com/eclipse/milo/blob/dev/0.3/milo-examples/server-examples/src/main/java/org/eclipse/milo/examples/server/ExampleNamespace.java) from Milo is also worth looking at if you’re playing with the new Device API, since it’s basically just an extension of a Milo Namespace.

There’s also some node builder usages in there.

Thank you, those examples are very helpful!
