JSON Schema Matching: Empirical Observations

Proceedings of the 2020 ACM SIGMOD International Conference on Management of Data, 2020
Database schema specifies the desired logical organization of the data it stores. A major challenge in database integration is that of schema matching [10, 12], which seeks to determine schema elements in different databases that correspond to the same real world entity. For example, a simple matcher may determine that the attribute ID in one schema is

Witness Generation for JSON Schema Patterns

2023
JSON Schema is a schema language for the popular data exchange format JSON. This paper introduces an approach to convert regular expressions, which appear in ECMA-262 syntax in JSON Schema, into an alternative syntax such that they may be compiled to finite-state automata.This is a step towards generating witnesses, i.e., JSON instances which are valid

Definition of REST web services with JSON schema

Software: Practice and Experience, 2016
SummaryThe Web has evolved from being a collection of documents to a collection of interconnected services that interoperate throughout the Internet. Web services are a natural consequence of this evolution. The web services model was initially centered around the eXtensible Markup Language (XML).

Nested Schema Mappings for Integrating JSON

2018
JSON has become one of the most popular data formats. Yet studies on JSON data integration (DI) are scarce. In this work, we study one of the key DI tasks, nested mapping generation in the context of integrating heterogeneous JSON based data sources.

JTutor: JSON Schema Validation Explained

Proceedings of the 19th International Symposium on Database Programming Languages
JSON Schema validators are essential tools in the JSON ecosystem. However, today's validators are primarily designed to be used programmatically. Even web-based tools are not didactic in their feedback regarding the oftentimes subtle interactions between schemas and JSON instances.

The JSON Schema: JSON Structure Validation

2016
Now that you have had an overview of the JSON data-definition language, this chapter looks at the schema that defines JSON, including the concepts behind the JSON Schema, advantages of using it, terms used to describe it, and the various rules that dictate its definition and design approach.

Streaming Validation of JSON Documents against Schemas [PDF]

Proceedings of the VLDB Endowment
JSON is a popular data format for storing semi-structured data. We investigate the computational problem of JSON validation, which is the task of checking whether a JSON document adheres to a given schema. While there are several existing tools that support JSON validation, they implement offline algorithms that require loading the entire document in ...

Schema-Aware Conversion of XML to JSON

Balisage Series on Markup Technologies, 2023
A W3C Community Group has been formed to develop proposed specifications for 4.0 versions of XSLT, XPath, and XQuery. One of the aims is to provide improved capabilities for processing of JSON, and the associated constructs in the data model such as maps and arrays.

A JSON Schema for RDAP

2018
This document presents a comprehensive JSON Schema for RDAP. The proposed schema has been used to validate, in some JUnit tests, the responses of the servers listed in IANA RDAP Bootstrap Registries.

A JSON Schema for jCard

2018
This document presents a comprehensive JSON Schema for jCard. The proposed schema has been used to validate a set of jCard examples within a JUnit test. Most of the examples have been extracted from the RDAP responses of servers listed in IANA RDAP Bootstrap Registries.
