JSON validation against JSON schemas: Why is this obvious JSON data not failing validation -

-

this json file should fail validation not. tell me why.

plug below json data , schema web site, validate,
http://json-schema-validator.herokuapp.com , same results in mule validate json schema. not comply schema (i added fields, misspelled fields, date-time value not real date time) yet not fail it. can tell me why?

json schema:

{   "$schema": "http://json-schema.org/draft-04/schema#",   "id": "http://hud.gov/ocio/xsd/esb/serviceauditingframework/2.0#",   "definitions": {     "serviceauditlogdata": {       "type": "object",       "title": "serviceauditlogdata",       "required": [         "servicerequesttimestamp",         "sourcesystem"       ],       "properties": {         "auditid": {           "type": "string"         },         "servicerequesttimestamp": {           "type": "string",           "format": "date-time"         },         "serviceprovider": {           "type": "string"         },         "serviceproviderversion": {           "type": "string"         },         "serviceprovidertimestamp": {           "type": "string",           "format": "date-time"         },         "eventtype": {           "type": "string"         },         "eventdetail": {           "type": "string"         },         "hostname": {           "type": "string"         },         "sourcesystem": {           "type": "string"         },         "authenticationid": {           "type": "string"         },         "enduserid": {           "type": "string"         },         "inputdata": {           "type": "string"         }       },       "propertiesorder": [         "auditid",         "servicerequesttimestamp",         "serviceprovider",         "serviceproviderversion",         "serviceprovidertimestamp",         "eventtype",         "eventdetail",         "hostname",         "sourcesystem",         "authenticationid",         "enduserid",         "inputdata"       ]     }   } }

json data

   {       "serviceauditlogdata": {         "junk":"asdfasdf",         "servicerequesttimestamp": "2004-09-29t12:58:31.470z",         "serviceprovider": "flqs",         "serviceproviderversion": "v1.0.1",         "audit_id": "17f24136-2494-4bf8-9d3b-9baafaae0cc9",         "serviceprovidertimestamp": "2012-11-04t21:44:57.997z",         "eventtype": "query pool",         "eventdetail": "default pool",         "hostname": "esb-d-srv1.",         "sourcesystem": "lrs",         "authenticationid": "esblrsaccount",         "enduserid": "h574857",         "inputdata": "l234234234, l32453462345, l23452346"       }     }

it not fail because schema not enforce constraint. notice definitions not jsonschema keyword constraints validation. used place sub-schemas re-used in other parts of schema definition. thus, start with, should change definitions keyword properties.

another common misunderstanding jsonschema related properties keyword. let's take following example:

{     "type" : "object",     "properties" : {         "key1" : {             "type" : "string"         }     } }

you must read as: json must object, , in case contains key equal key1, value must string. according following 2 json objects valid:

{     "key2":12 }

and:

{     "key1":"sdf" }

finally, related date-time format, must check section 6 of rfc3339 sure have valid date-time. , in case, implementation of formats not compulsory in jsonschema validators.
