Could it cread ModellingRule? about opcua-modeler HOT 10 CLOSED

OK, HasModellingRule is a type reference and reference editor is not implemented yet. But this is very high on my todo list. Should have a look..

I also do not know how to use ModellingRule. If you can explain we can probably add it.

This is a variant which can be implemented in address space:
"<UAVariable BrowseName="1:State" DataType="Float" NodeId="ns=1;i=2008" ParentNodeId="ns=1;i=2005">
<DisplayName>State<\DisplayName>
<Description>State<\Description>
<References>
<Reference IsForward="false" ReferenceType="HasComponent">ns=1;i=2005<\Reference>
<Reference ReferenceType="HasModellingRule">i=78<\Reference>
<Reference ReferenceType="HasTypeDefinition">i=63<\Reference>
<\References>
<Value>
uax:Float\9.99<\uax:Float>
<\Value>
<\UAVariable>"
where the reference(<Reference ReferenceType="HasModellingRule">i=78<\Reference>) can't be added in free uamodeler.
As I know, the ModellingRule includes Mandatory and Optional at least. If the ModellingRule of a variant is not Mandatory, the address space may not implement it, but there is a need to implement that variant.

Do you have anything started with this? If you have some code already I might have time to help out with this.

I have a lot of copy paste code. I need to make the basic work, then I can publish for testing/improvement

started work here. FreeOpcUa/opcua-widgets#8
not finished. I am not sure how to modify a reference. Looks like I need to delete and rewrite it

I'll take a look at it.
