The last few years have seen the fast and ubiquitous diffusion of JSON as one of the most widely used formats for publishing and interchanging data, as it combines the flexibility of semistructured data models with well-known data structures like records and arrays. The user willing to effectively manage JSON data collections can rely on several schema languages, like JSON Schema, JSound, and Joi, or on the type abstractions offered by modern programming languages like Swift or TypeScript. The main aim of this tutorial is to provide the audience with the basic notions for enjoying all the benefits that schemas and types can offer while processing and manipulating JSON data. This tutorial focuses on four main aspects of the relation between JSON and schemas: (1) we survey existing schema language proposals and discuss their prominent features; (2) we review how modern programming languages support JSON data as first-class citizens; (3) we analyze tools that can infer schemas from data, or that exploit schema information for improving data parsing and management; and (4) we discuss some open research challenges and opportunities related to JSON data.

Abstract

The last few years have seen the fast and ubiquitous diffusion of JSON as one of the most widely used formats for publishing and interchanging data, as it combines the flexibility of semistructured data models with well-known data structures like records and arrays. The user willing to effectively manage JSON data collections can rely on several schema languages, like JSON Schema, JSound, and Joi, or on the type abstractions offered by modern programming languages like Swift or TypeScript. The main aim of this tutorial is to provide the audience with the basic notions for enjoying all the benefits that schemas and types can offer while processing and manipulating JSON data. This tutorial focuses on four main aspects of the relation between JSON and schemas: (1) we survey existing schema language proposals and discuss their prominent features; (2) we review how modern programming languages support JSON data as first-class citizens; (3) we analyze tools that can infer schemas from data, or that exploit schema information for improving data parsing and management; and (4) we discuss some open research challenges and opportunities related to JSON data.
