I observed that when I rename a model entity – by calling smtk;:model::EntityRef::setName() – the model resource’s clean flag does **not** get reset to the false state. (I can post a test to demonstrate.) Should that be changed, or if not, should we add a comment in EntityRef.h that setName() does not affect the resource clean flag?

Only operations invoke observers to inform them that things have changed. You should use the [SetProperty](https://gitlab.kitware.com/cmb/smtk/-/blob/master/smtk/operation/operators/SetProperty.sbt) operation to set a string property on the component. Then all of the updates you expect should occur.

Got it, thanks. I presume, then, that the entity name is now/also a string property with the property name “name”.
Next time we update smtk/resource/Resource.h, maybe we should expand on the comment for the clean() method:
```auto
/// Indicate whether the resource is in sync with its location.
```
It would be good to state that applications making direct API calls must also call `setClean()` to reset the flag.
