The Calling REST APIs section demonstrates how to use LoopBack 4 to call GET APIs. It would be benefiting to the broader community to demonstrate how to call POST APIs. I have the todo-jwt example hosted in Heroku that could be used in the doc

class DerivedMetadata(Metadata):
    def ok(self):
        print("ok")

md = DerivedMetadata.from_file("root.json")
md.ok() # fails because md type is Metadata, not DerivedMetadata

This seems to happen because the construction path goes

• DerivedMetadata.from_file()
• DerivedMetadata.from_bytes()
• JsonDeserializer.deserialize() _here deserializer doesn't know the corre

Describe the bug
In #3322 the new relationships file was added to the SAF (Simple Archive Format) package structure to allow for the creation of new relationships between Entities. This same file should also be written on export of Entities, to better support "round-tripping" of SAF packages.

Ideally, this round-tripping might also be tested via ITs, see also #7980
