/***
 * A container for signed TUF metadata.
 *
 * Provides methods to convert to and from json, read and write to and
 * from JSON and to create and verify metadata signatures.
 *
 * ``Metadata[T]`` is a generic container type where T can be any one type of
 * [``Root``, ``Timestamp``, ``Snapshot``, ``Targets``]. The purpose of this
 * is to allow static type checking of the signed attribute in code using
 * Metadata::
 *
 * root_md = Metadata[Root].fromJSON("root.json")
 * # root_md type is now Metadata[Root]. This means signed and its
 * # attributes like consistent_snapshot are now statically typed and the
 * # types can be verified by static type checkers and shown by IDEs
 *
 * Using a type constraint is not required but not doing so means T is not a
 * specific type so static typing cannot happen. Note that the type constraint
 * ``[Root]`` is not validated at runtime (as pure annotations are not available
 * then).
 *
 * Apart from ``expires`` all of the arguments to the inner constructors have
 * reasonable default values for new metadata.
