  • Seems useful.
    The 'Sample GET' slides and 'Sample PATCH' one should probably use the same object names for better understanding.
    Same for the FORM-based examples.

Transcript

  • 1. Introducing: JSOP
  • 2. Pitch & Goal - Browser enabled, HTTP-based protocol designed to exchange fine-grained information efficiently. - Easy to consume by todays Web-”Gear” (browsers, flash & friends) - Probably suitable for an RFC @ IETF
  • 3. Basics - Serialization to JSON (optionally YAML/XML) - GET (batch/hierarchical) - PUT (batch/hierarchical) - PATCH (json diff content type) - Support for binary as multipart
  • 4. Retro-style - PUT & PATCH -> multipart POST - Allows for Simple HTML forms
  • 5. Extensions - Sort-Order - Query - Typing - Locking - Versioning - Essentially: WebDAV + friends but simple
  • 6. Sample GET Request: GET /myfolder.json HTTP/1.1 Response: { "createdBy" : "uncled", "name" : "myfolder", "id" : "50d9317a-3a95-401a-9638-333a0dbf04bb" "type" : "folder" }
  • 7. Sample GET 2 Request: GET /myfolder.4.json HTTP/1.1 Response: { "createdBy" : "uncled", "name" : "myfolder", "id" : "50d9317a-3a95-401a-9638-333a0dbf04bb" "type" : "folder" "child1" : { "grandchild11" : { "depth3" : { "depth4 : { ... } } } } }
  • 8. Sample PUT PUT /myfolder HTTP/1.1 { "createdBy" : "uncled", "name" : "myfolder", "id" : "50d9317a-3a95-401a-9638-333a0dbf04bb" "type" : "folder" "child1" : { "grandchild11" : { "depth3" : { "depth4 : { ... } } } } }
  • 9. Sample PATCH PATCH /myfolder HTTP/1.1 +newdoc : { "type" : "document", "createdBy" : "me" } -olddoc >movingdoc : /otherfolder/mydocument ^lastModifiedBy : "me"
  • 10. PATCH diff ops "+": create Node/Property/Resource "^": update Node/Property/Resource "-": delete Node/Property/Resource ">": move Node/Property/Resource
  • 11. PATCH diff diff ::= members members ::= pair | pairs pair ::= key [ " : " value ] pairs ::= pair line-end pair | pair line-end pairs line-end ::= "rn" | "n" | "r" key ::= opchar id opchar ::= "+" | "^" | "-" | ">" id ::= * identification url (path | id) * value ::= value+ | value- | value^ | value> value+ ::= * a JSON object * value- ::= "" value^ ::= * any JSON value except JSON object * value> ::= id
