 The `Link object` represents a possible design-time link for a result.
 The presence of a link does not guarantee the caller's ability to successfully invoke it, rather it provides a known relationship and traversal mechanism between results and other methods.

+Unlike *dynamic* links (i.e. links provided **in** the result payload), the OpenRPC linking mechanism does not require link information in the runtime result.
 
 For computing links, and providing instructions to execute them, a [runtime expression](#runtime-expression) is used for accessing values in an method and using them as parameters while invoking the linked method.
