Introducing JSON Structure - A Better Schema
#1about 5 minutes
Why JSON Schema fails as a data definition language
JSON Schema's complexity with validation constructs like `allOf` and `anyOf` makes it a poor choice for defining data types, leading to a stalled standard.
#2about 2 minutes
Introducing JSON Structure as a type definition language
JSON Structure refactors JSON Schema into a strict type definition language with required types, named objects, and new built-in primitive types for better code generation.
#3about 2 minutes
Using new compound types like map and tuple
JSON Structure introduces formal compound types like `map` for dictionaries and `tuple` for creating efficient, compact wire formats for time-series data.
#4about 4 minutes
Defining discriminated unions and organizing types
Use the `choices` keyword for formal discriminated unions and organize schemas with namespaces and a restricted `$ref` for cleaner mapping to programming languages.
#5about 3 minutes
Managing dependencies with imports and explicit inheritance
Separate file inclusion from type referencing with `$import` and use `abstract` and `extends` for clear, unambiguous type inheritance.
#6about 4 minutes
Extending schemas with companion specifications
Add functionality through optional companion specs for internationalization, scientific units, currencies, and even re-introducing validation rules from JSON Schema.
#7about 2 minutes
How to get involved with the JSON Structure standard
JSON Structure is a new IETF draft, and community participation through filing issues and providing feedback at jsonstructure.org is encouraged.
