libjson-rpc-common-perl 0.11-2 (s390x binary) in ubuntu noble

 JSON::RPC::Common provides abstractions for JSON-RPC 1.0, 1.1 (both
 variations) and 2.0 (formerly 1.2) Procedure Call and Procedure Return
 objects (formerly known as request and result), along with error objects. It
 also provides marshalling objects to convert the model objects into JSON text
 and HTTP requests/responses.
 .
 This module does not concern itself with the transport layer at all, so the
 JSON-RPC 1.1 and the alternative specification, which are very different on
 that level are implemented with the same class.
