Piqi-RPC is an RPC-over-HTTP system for Erlang.
Piqi-RPC gives Erlang developers a convenient and reliable way to connect services written in Erlang with the rest of the world using JSON, XML or Google Protocol Buffers over plain HTTP.
Basically, Piqi-RPC can be viewed as an HTTP gateway for Erlang functions. Any standard HTTP client can communicate with them not knowing anything about Erlang or Piqi-RPC. And the opposite is also true: Erlang functions work with idiomatic Erlang data structures and don’t have to be aware of HTTP or even Piqi-RPC.
In other words, Piqi-RPC system automates several areas where Erlang developers usually need to write (and maintain!) a lot of boring plumbing code:
Parsing and validating input parameters -- Piqi-RPC automatically parses XML, JSON, Protocol Buffers and command-line arguments, validates them and converts to idiomatic Erlang data structures.
Generating output parameters -- again, Piqi-RPC automatically generates XML, JSON and Protocol Buffers from native Erlang representation.
HTTP communication -- Piqi-RPC provides fully-compliant HTTP communication layer. It receives and validates HTTP requests, sends responses, handles "Content-Type" and "Accept" headers and generates around 10 different meaningful HTTP response types for various error conditions that can occur during request execution.
