Hi ,
i am trying to define a schema validation for schema that need to contain :
{ "a" :"a value",
"b":"b value" ,
"c":"c value" ,
"properties":{
"property1Name":{
"type" :"type value",
"field1":"field1value",
"field2":"field2value"
},
"property2Name":{
"type" :"type value",
"field1":"field1value",
"field2":"field2value"
}
}
}

i define a schema to validate the restrications on each instance :
{
"a":{"type":"string"} ,
"b":{"type":"string"},
"c" :{"type":"string"} ,
"required": ["a","b","c","properties"]
}
how can i add the restriction for this properties part ? that each property will contain "field1" and "field2" ?

Thanks,
Reut

Hi,

if you want that properties "property1Name" etc. are flexible you could use
"additionalProperties". Otherwise you could also hardcode the properties. Take a 
look at the following schema:

{
"type": "object",
"properties": {
"a": {
"type": "string"
},
"b": {
"type": "string"
},
"c": {
"type": "string"
},
"properties": {
"type": "object",
"additionalProperties": {
"type": "object",
"properties": {
"type": {
"type": "string"
},
"field1": {
"type": "string"
},
"field2": {
"type": "string"
}
}
}
}
},
"required": ["a","b","c","properties"]
}

Means basically inside the "properties" property you can have variable keys 
which must have as value an object with the "type", "field1" properties etc.

best regards
Christoph

hi , 
thanks for your answer . i tried the solution you offer .
my schema now look like this  :
{
  "a": {
  "type": "string"
  },
  "b": {
  "type": "string"
  },
  "c": {
  "type": "string"
  },
  "d": {
  "type": "string"
  },
  "e": ["string"],
  "f": {
  "type": "string"
  },
  "properties": {
  "additionalProperties": {
  "type": "object",
  "properties": {
  "type": {
  "type": "string"
  },
  "field1": {
  "type": "string"
  } 
  },
              "required": ["type", "field1"]
  }
  },
  "required": ["a", "b", "c", "d", "properties"]
 }
when i try to validate with this schema the instance : i am not getting any error for that "field1" is missing . Do you have any idea about this ?
{
  "a": "aval",
  "b": "bval",
  "properties": {  
    "prop name": {
    "type": "number",
      "field222": "text box",
      "default": 60
    }
  }
}

Thanks,
Reut
