Add wrap for koral:distance and cosmas:distance

[margaretha]

For coherence, wrap should be added in koral:distance and cosmas:distance for specifying the scope of the distance, e.g. sentence.

{
  "@type" : "koral:distance",
  "wrap" : {
    "@type" : "koral:term",
    "foundry" : "base",
    "layer" : "s",
    "key" : "s"
  }
  "boundary" : {...}
}

For token distance such as "w" in C2, the key attribute should be replaced with "koral:token" as follows:

{
  "@type" : "cosmas:distance",
  "wrap" : {
    "@type" : "koral:token"
  }
  "boundary" : {...}
}

Maybe it's more appropriate to have an "operand" key that wraps a span or a token, that then wraps a term (as usual)?

[margaretha]

Yes sure, so for clarification, the serialization should be as follows.

Sentence

{
    "@type": "koral:distance",
    "key": {
        "@type": "koral:span",
        "wrap": {
            "@type": "koral:term",
            "foundry": "base",
            "layer": "s",
            "key": "s"
        }
    },
    "boundary": {...}
}

Term

{
    "@type": "cosmas:distance",
    "key": {
        "@type": "koral:token"
    },
    "boundary": {...}
}

[Akron]

I literally meant operand, because operand and wrap are the keys to follow for the rewrite, right?
And regarding distances: I guess we agree that exclusion is different to "distance", so we may want to think about renaming distances as a key to constraints and introduce koral:exclusion and cosmas:exclusion?
