Representation of property values that are defined terms

[simleo]

In Recording changes to RO-Crates, we have examples that represent the value of actionStatus like:

  "actionStatus":  {"@id": "http://schema.org/CompletedActionStatus"}

However, there are some TRE-FX profile examples that use:

  "actionStatus": "http://schema.org/CompletedActionStatus"

Are they both correct? And since CompletedActionStatus is defined in the RO-Crate context, isn't the following also correct?

  "actionStatus": "CompletedActionStatus"
