AVRO schema for JSON Patch document - avro

the JSON Patch document defined in rfc6902 has a field value that can basically be of any type.
[
{ "op": "test", "path": "/a/b/c", "value": "foo" },
{ "op": "remove", "path": "/a/b/c" },
{ "op": "add", "path": "/a/b/c", "value": [ "foo", "bar" ] },
{ "op": "replace", "path": "/a/b/c", "value": 42 },
{ "op": "add", "path": "/biscuits/1", "value": { "name": "Ginger Nut" } }
]
value:
description: The value to be used within the operations.
nullable: true
anyOf:
- type: string
- type: number
- type: integer
- type: boolean
- type: array
items: {}
- type: object
How could such a value field be defined in an avro schema

Time Series Insights not showing sub-object properties of a key/value pair

I have an application that is pushing data into IoT Hub which is being used as a data source for TSI. Below is an example message:
{
"EnqueuedTimeUtc": "2021-06-17T22:00:47.2170000Z",
"Properties": {},
"SystemProperties": {
"connectionDeviceId": "Device1",
"connectionAuthMethod": "{\"scope\":\"device\",\"type\":\"sas\",\"issuer\":\"iothub\",\"acceptingIpFilterRule\":null}",

},
"Body": {
"topic": {
"namespace": "spBv1.0",
"edgeNodeDescriptor": "Routed Group/E2",
"groupId": "Routed Group",
"edgeNodeId": "E2",
"deviceId": "D2",
"type": "DBIRTH"
},
"payload": {
"timestamp": "2021-06-17T22:00:47.082Z",
"metrics": [{
"name": "Ramp1",
"timestamp": "2021-06-17T22:00:47.082Z",
"dataType": "Int32",
"metaData": {},
"properties": {
"Quality": {
"type": "Int32",
"value": 192
},
"My Property": {
"type": "String",
"value": "{\"\":\"\"}"
}
},
"value": 77
}],
"seq": 1
}
}
}
I found documentation showing that my array of 'metrics' is supported as shown here:
https://learn.microsoft.com/en-us/azure/time-series-insights/concepts-json-flattening-escaping-rules
With this message, I can see 'Ramp1' show up in TSI with a value and timestamp as expected. However, the 'properties' under each metric do not show up. In this example that is 'Quality' and 'My Property'. Is there a way to get this data into TSI with an association to 'Ramp1'?

Swagger array of different objects

For example I need to represent following structure in swagger yaml format:
"included": [
{
"type": "people",
"id": "42",
"attributes": {
"name": "John",
"age": 80,
"gender": "male"
}
}
]
With single object everything is fine:
included:
type: "array"
items:
type: object
properties:
type:
type: "string"
# and so on
The question is what if I need to describe something like:
"included": [{
"type": "people",
"id": "9",
"attributes": {
"first-name": "Dan",
"last-name": "Gebhardt",
"twitter": "dgeb"
},
"links": {
"self": "http://example.com/people/9"
}
}, {
"type": "comments",
"id": "5",
"attributes": {
"body": "First!"
},
"relationships": {
"author": {
"data": { "type": "people", "id": "2" }
}
},
"links": {
"self": "http://example.com/comments/5"
}
}, {
"type": "comments",
"id": "12",
"attributes": {
"body": "I like XML better"
},
"relationships": {
"author": {
"data": { "type": "people", "id": "9" }
}
},
"links": {
"self": "http://example.com/comments/12"
}
}]
I know that in OpenAPI it's possible ( aka swagger 3 ) and tried some workarounds in current version but with no luck.

How to define an enum in OpenAPI (Swagger)?

Does anyone know how to define possible enum values in an OpenAPI 2.0 definition so that they will be displayed in the Model tab of Swagger UI? Example here has an enum option for the status property. How to do define such an enum in OpenAPI 2.0?
"enum" works like this in OpenAPI 2.0:
{
"in": "query",
"name": "sample",
"description": "a sample parameter with an enum value",
"type": "string",
"enum": [ "1", "2"],
"required": true
}
and in OpenAPI 3.0:
{
"in": "query",
"name": "sample",
"description": "a sample parameter with an enum value",
"schema": {
"type": "string",
"enum": [ "1", "2"]
},
"required": true
}
As you can see, there's a query parameter called sample of type string, and has an enum stating two possible values. In this case, the sample states the parameter is required, so the UI will not show an empty value as an option.
For a minimal working sample, try this:
{
"swagger": "2.0",
"info": {
"title": "title",
"description": "descriptor",
"version": "0.1"
},
"paths": {
"/sample": {
"post": {
"description": "sample",
"parameters": [
{
"in": "query",
"name": "sample",
"description": "a sample parameter with an enum value",
"type": "string",
"enum": [
"1",
"2"
],
"required": true
}
],
"responses": {
"200": {
"description": "Successful request."
}
}
}
}
}
}
To test it locally, you can declare a variable (for example spec) in your javascript, and pass it into the SwaggerUi object.
var spec = { ... };
window.swaggerUi = new SwaggerUi({
url: url,
spec: spec,
dom_id: "swagger-ui-container",
supportedSubmitMethods: ['get', 'post', 'put', 'delete'],
onComplete: function(swaggerApi, swaggerUi){
...
The url parameter will be ignored in this case.
Eventually, the output looks like this:
Updating this with YAML syntax.
OpenAPI 2.0:
parameters:
- in: query
name: sample
description: a sample parameter with an enum value
type: string
enum:
- 1
- 2
required: true
OpenAPI 3.0:
parameters:
- in: query
name: sample
description: a sample parameter with an enum value
schema:
type: string
enum:
- 1
- 2
required: true
This should work:
{
"name": "bookingType",
"in": "path",
"type": "array",
"items": {
"enum": [
"packages", "accommodations"
]
},
"description": "lorem ipsum"
}
Reference https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md#itemsObject
This isn't the exact answer, but it might work for you until they add this functionality.
Simply declare the property like so
"MyObject":{
"properties":{
"MyEnum":{
"type":"Value1 or Value2 or Value3"
}
}
}
Your ModelSchema will show {}, but The Model will show MyEnum(Value1 or Value2 or Value3, optional)

How to add data to a custom HighChart's HighMaps map? joinBy?

I created a custom map using Inkscape as described on the HighMaps docs pages at: http://www.highcharts.com/docs/maps/custom-maps
Everything up to step 16 seems to go smoothly.
Step 16 says that the only remaining thing to do is to add data or use the MapData option and this is where I am struggling.
How does one link the custom shapes in the map to data points? Using the shape name in a JoinBy?
http://jsfiddle.net/GeertClaes/aWJ2D/
$(function () {
// Initiate the chart
$('#container').highcharts('Map', {
title:{text:''},
subTitle:{text:''},

}

}

});
});
There's a couple of ways:
1.) The easiest is to add it into your data using the value property. This is discouraged because it hardcodes the value for the map paths:
"data": [
{
"name": "Status1-CurrentPeriod",
"path": "M0,-695,0,-682C1,-682,2,-683,3,-683,15,-683,25,-672,25,-658,25,-645,15,-634,3,-634,2,-634,1,-634,1,-634L1,-622,108,-622,107,-694,0,-695z",
"value": 6 // <-- here's a numerical value for this path
}
2.) Seperate your mapData from your data. Map the values in mapData to the values in data with a joinBy. This makes your map paths reusable:
series: [{
"type": "map",
"joinBy": ['name', 'name'], // <- mapping 'name' in data to 'name' in mapData
"data": [
{
"name": "Status1-CurrentPeriod",
"value": 6
}
],
"mapData": [
{
"name": "Status1-CurrentPeriod",
"path": "M0,-695,0,-682C1,-682,2,-683,3,-683,15,-683,25,-672,25,-658,25,-645,15,-634,3,-634,2,-634,1,-634,1,-634L1,-622,108,-622,107,-694,0,-695z"
}
...
}]

How do I use the swagger models section?

Inside the Swagger API Documentation there is inside the json beside the apis array a model object entry but no documentation about it. How can I use this "models" part?
{
apiVersion: "0.2",
swaggerVersion: "1.1",
basePath: "http://petstore.swagger.wordnik.com/api",
resourcePath: "/pet.{format}"
...
apis: [...]
models: {...}
}
Models are nothing but like your POJO classes in java which have variables and properties. In models section you can define your own custom class and you can refer it as data type.
If you see below
{
"path": "/pet.{format}",
"description": "Operations about pets",
"operations": [
{
"httpMethod": "POST",
"summary": "Add a new pet to the store",
"responseClass": "void",
"nickname": "addPet",
"parameters": [
{
"description": "Pet object that needs to be added to the store",
"paramType": "body",
"required": true,
"allowMultiple": false,
"dataType": "Pet"
}
],
"errorResponses": [
{
"code": 405,
"reason": "Invalid input"
}
]
}
Here in parameter section it have one parameter who's dataType is Pet and pet is defined in models as below
{
"models": {
"Pet": {
"id": "Pet",
"properties": {
"id": {
"type": "long"
},
"status": {
"allowableValues": {
"valueType": "LIST",
"values": [
"available",
"pending",
"sold"
]
},
"description": "pet status in the store",
"type": "string"
},
"name": {
"type": "string"
},
"photoUrls": {
"items": {
"type": "string"
},
"type": "Array"
}
}
}
}}
You can have nested models , for more information see Swagger PetStore example
So models are nothing but like classes.
