		 *
		 * Registered CURIES need to specify a name and URI template. This will

		 * The shortened relation follows the format `{name}:{rel}`. `{rel}` in
		 * the URI template will be replaced with the `{rel}` part of the
		 * shortened relation.
		 *
		 * For example, a CURIE with name `example` and URI template
		 * `http://w.org/{rel}` would transform a `http://w.org/term` relation
		 * into `example:term`.
		 *
		 * Well-behaved clients should expand and normalize these back to their
		 * full URI relation, however some naive clients may not resolve these
		 * correctly, so adding new CURIEs may break backward compatibility.
