# MongoDB Object ID representation.
#
# For ObjectIDs, MongoDB uses the `ObjectId("hash")` notation.
# This notation is replicated by the `to_s` service.
#
# Since the MongoDB notation is not JSON complient, the mongoc wrapper uses
# a JSON based notation like `{"$oid": "hash"}`.
# This is the notation returned by the `to_json` service.
