GraphQL for RDF/SHACL

GraphQL is a highly popular data query and manipulation language. It allows clients to define the structure of the data they require, and exactly the same structure of the data in JSON is returned from the server. GraphQL was developed internally by Facebook in 2012 before being publicly released in 2015. Since then, GraphQL use, development community and available tools have been rapidly growing.

GraphQL for RDF/SHACL provides powerful access to RDF data​ by seamlessly combining W3C standards for schema definition, data validation, inferencing and query​, with a ​popular ​JSON-centric ​query language for APIs​.​ This makes RDF data easily available to the JSON and browser ecosystems.

TopBraid uses RDF to store and organize data. This means it offers great flexibility and solid standards to represent almost any data structure. You can combine tables and objects from multiple sources into an enterprise knowledge graph.

W3C Standards (RDF Schema, SHACL and OWL) or GraphQL's own schema language are used to define types and fields with rich semantic rules and constraints. This approach uses GraphQL directives to significantly improve the value of GraphQL schemas for JSON-based data processing. You can define multiple views for the same data, supporting whatever data shape your application prefers.

This combination is used to automatically generate query schemas for use with GraphQL including powerful features to select, filter, aggregate, dynamically compute and page results. It also includes full support for SPARQL, and lets you use the schemas to validate updates from using SHACL shapes.
