A description of the link. CommonMark syntax MAY be used for rich text representation.
The name of an existing, resolvable OAS operation, as defined with a unique operationId. This field is mutually exclusive of the operationRef field.
A relative or absolute URI reference to an OAS operation. This field is mutually exclusive of the operationId field, and MUST point to an OasOperation object. Relative operationRef values MAY be used to locate an existing OasOperation object in the OpenAPI definition.
A map representing parameters to pass to an operation as specified with operationId or identified via operationRef. The key is the parameter name to be used, whereas the value can be a constant or an expression to be evaluated and passed to the linked operation. The parameter name can be qualified using the parameter location [{in}.]{name} for operations that use the same parameter name in different locations (e.g. path.id).
A link to request bodies defined in the [OasDocument's] components/links.
A literal value or {expression} to use as a request body when calling the target operation.
A server object to be used by the target operation.
The Link object represents a possible design-time link for a response. 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 responses and other operations.
Unlike *dynamic* links (i.e. links provided in the response payload), the OAS linking mechanism does not require link information in the runtime response.
For computing links, and providing instructions to execute them, a [runtime expression](https://swagger.io/specification/#runtime-expression) is used for accessing values in an operation and using them as parameters while invoking the linked operation.
