Add example of the initial overrided object

[joeitu]

Hi,
in the override doc if I understand correctly the first example override an ex:myHelloWorldWithOverride object.

Since we don't know what the first object looks like it is hard to tell is part of the original object or what should be directly copied.

For eg. "@type": "Override",
Is "Override" the type of the initial object or should it be the type when writing an override?

Sorry if this seems a bit confusing, but in short I think an example of the original overridden object would be helpful to make the example clearer.

Override is a special type to indicate that this object overrides the values of another object. So the original object could look something like:

{
  "@id": "ex:myHelloWorldWithOverride",
  "@type": "hello:HelloWorld",
  "hello:say": "HELLO",
  "hello:hello": "WORLD",
  "hello:punctuation": "!"
}

I'll look into updating the example.
