Valid an inbound IMS document against a Json schema

Sam Barnes

Is there any means of validating inbound IMS document content against an ION data catalog schema? In other words, if I have a json schema for a document defined in ION Data Catalog and an IMS connection point that accepts that document type. Is it possible to validate the content being sent against the schema such that the message is rejected if it doesn't match the schema?

My understanding is that the IMS api call will be successful regardless of whether the content is valid ( assuming the headers are correct and the content is well formed).

A suggestion would be to use the Scripting for that object after the IMS endpoint accepting. As an example, that could be done with jsonschema.validate

import json

from jsonschema import validate, ValidationError


# Example JSON schema

myJSONSchema = {

    "type": "object",

    "properties": {

        "name": {"type": "string"},

        "age": {"type": "number"},

    },

    "required": ["name", "age"]

}


# Example JSON data

data = {

    "name": "Kevin",

    "age": 35

}


# Validate the JSON data

try:

    validate(instance=data, schema=myJSONSchema)

    print("JSON is valid.")

except ValidationError as e:

    print("JSON is invalid:", e.message)
