Json Schema Validation

• SchemaJSON.scala represents schema model of the json data

• ValidateJSON.scala validation of schema model

• ReadJSON.scala read json files from resource or url

• If validation is success it will print a Success message

• If validation failed, it will print a Error message with error values.

Launch the Execution

• Run
  • sbt run (it will download necessary librabry to execute the code)

Expected Result

• For Success Case
  • val json = Json.parse(readJson1)

Set(name, web_pages, alpha_two_code, domains, country, state-province)
Validation Success
Key is state-province and number of null values is 9659

• For Failure Case
  • Change the value json as readJson2 - val json = Json.parse(readJson2)

Set(name, web_pages, alpha_two_code, domains, country, county, state-province)
