JSON Referencing and Schema
- 1. Persistent Computing on the Web with JSON Schema and Referencing Kris Zyp
- 2. Overview JSON Referencing JSON Schema The possiblities...
- 3. JSON + Hyperlinks = JSON Referencing
- 4. JSON Referencing Cyclic Multiple references Cross-message references Cross-site references http://www.sitepen.com/blog/2008/06/17/json-referencing-in-dojo/
- 5. JSON Referencing (ID Based) { “ name”:”Kris Zyp”, “ id”:”kriszyp”, “children”:[{“id”:”jennikazyp”,“name”:”Jennika Zyp”}], “ spouse”:{ “ name”:”Nicole Zyp”, “spouse”:{“$ref”:”kriszyp”}, “ children”:[{“$ref”:”jennikazyp”}] } }
- 6. JSON Referencing (Path Based) { “ name”:”Kris Zyp”, “children”:[{“name”:”Jennika Zyp”}], “ spouse”:{ “ name”:”Nicole Zyp”, “spouse”:{“$ref”:”#”}, “ children”:{“$ref”:”#.children”} } }
- 7. JSON Referencing (ID + Path) { “ name”:”Kris Zyp”, “ id”:”kriszyp”, “children”:[{“name”:”Jennika Zyp”}], “ friends”:[{“$ref”:”jesse#.spouse”}] }
- 8. JSON + Schema = JSON Schema
- 9. JSON Schema schema: {"description":"A person", "type":"object", "properties": {"name": {"type":"string"}, "age" : {"type":"integer", "maximum":125}} } instance: {“name”:”Kris”, “ age”:30}
- 10. JSON Schema Schema: {"description":"A person", "type":"object", "properties": {"name": {"type":"string"}, "age" : {"type":"integer", "maximum":125, “optional”:true}, “friends”: {“type”:”array”, “items”:{“type”:”object”}} } } instance: {“name”:”Kris”, “ friends”:[{“name”:”Nikki”}] }
- 11. JSON Schema Schema: {“type”:”array”, “items”:[{“type”:”string”},{“type”:”number”}] } instance: [“foo”,44]
- 12. JSON Schema Schema: {"description":"A person", "type":["object",”string”] } instance: “ foo” instance: {“prop”:3}
- 13. JSON Schema Schema: {"description":"A person", "type":["object",”string”] } instance: “ foo” instance: {“prop”:3}
- 14. JSON Schema schema: {"description":"A person", "type":"object", "properties": {"name": {"type":"string"}, "gender" : {"type":"string", "enum”:[“male”,”female”]}}, “ additionalProperties”:false } instance: {“name”:”Kris”, “ gender”:”male”}
- 15. What can we do with these?
- 16. JSON Schema + JSON Referencing {"description":"A Social Person", “id”:”socialperson”, "type":"object", "properties": {"name": {"type":"string"}, "age" : { "type":"integer", "maximum":125 }, "friends" : { “ type” : ”array”, “ items” : {“$ref”:”socialperson”} } }, “ extends”:{“$ref”:”person”} }
- 17. JSON Referencing + REST Lazy loading - Generic clients can auto-load objects as necessary Object identification can be used for saving state changes http://blog.medryx.org/2008/07/24/jsonreststore-overview/
- 18. JSON Referencing + REST GET /Person/3 { “ name”:”Kris”, “ friends”:[ {“$ref”:”4”}, {“$ref”:”5”} ] }
- 19. JSON Referencing + JSON-RPC POST /person/kriszyp { “ method”:”addFriend”, “ id”:”1”, “ params”:[{“$ref”:”jessesmith”}] }
- 20. Applying data definitions to code
- 21. JSON Schema + Typed Code
- 23. JSON Schema Interface {"description":"A person", "type":"object", "properties": {"name": {"type":"string"} }, “methods”:{ “getName”:{“returns”:{“type”:”string”}, “params”:[]}, “setName”:{“params”:[{“type”:”string”}]}, } }
- 24. Cross-site Referencing { “ name”:”Kris Zyp”, “ id”:”kriszyp”, “ friends”:[ {“$ref”:” http://thezyps.com/person/nikki ”}, {“$ref”:” http://social.com/user/33 ”} ] }
- 26. Mobile code (run anywhere) Code can run anywhere Server JavaScript Environment Browser JavaScript Environment Consistent persisted data structures across environments
- 27. Connecting and structuring data for the future JSON Schema and JSON Referencing
