SOAPjr is a protocol specification for exchanging structured information in the implementation of Web services in computer networks. It is a hybrid of SOAP and JSON-RPC (abbreviated as "jr" in this case). ==Introduction== SOAPjr is designed to create clean, fast, AJAX-style APIs and is analogous to the introduction of out of band signalling in the telephony world. Traditional SOAP〔(【引用サイトリンク】 title=RFC 3902 : SOAP 1.2 Technical Report Recommendation )〕 is no longer the Simple Object Access Protocol it was initially designed to be. It can be bloated and overly verbose, making it bandwidth-hungry and slow.〔XML#Disadvantages_of_XML〕 It is also based on XML, making it expensive to parse and manipulate 〔(JSON may be up to 100x faster to parse than XML )〕 - especially on mobile or embedded clients.〔(Cheaper parsing of XML on Mobile Devices )〕 However, its core envelope/head/body design pattern is useful for AJAX style APIs.〔(Demonstration of SOAPjr and out-of-band error handling )〕 SOAPjr uses a similar Envelope/Head/Body model, using lightweight and easier to manipulate JSON.〔(JSON RFC )〕 In contrast to SOAP, JSON-RPC〔(JSON-RPC 1.1 Working Draft Specification )〕 is overly simplistic and basically tunnels HTTP〔(HTTP RFC )〕 GET-style key/value pairs within a query string using JSON. However, within JSON-RPC there is no head/body separation, leaving metadata to pollute the main data space. SOAPjr combines the best of these two concepts and is designed to create modern AJAX APIs that can easily be used by mobile devices, embedded systems or desktop browsers.
