Atomic Data is a modular specification for sharing, modifying and modeling graph data. It combines the ease of use of JSON, the connectivity of RDF (linked data) and the reliability of type-safety.

Atomic Data uses links to connect pieces of data, and therefore makes it easier to connect datasets to each other - even when these datasets exist on separate machines.

Atomic Data has been designed with the following goals in mind:

• Give people more control over their data
• Make linked data easier to use
• Make it easier for developers to build highly interoperable apps
• Make standardization easier and cheaper

Atomic Data is Linked Data, as it is a strict subset of RDF. It is type-safe (you know if something is a string, number, date, URL, etc.) and extensible through Atomic Schema, which means that you can re-use or define your own Classes, Properties and Datatypes.

The default serialization format for Atomic Data is JSON-AD, which is simply JSON where each key is a URL of an Atomic Property. These Properties are responsible for setting the datatype (to ensure type-safety) and setting shortnames (which help to keep names short, for example in JSON serialization) and descriptions (which provide semantic explanations of what a property should be used for).

Atomic Data has specifications for authentication, authorization, querying / filtering / pagination, event sourcing and versioning, file management, websockets, API endpoints and more.

Keep in mind that none of the Atomic Data project has reached a v1, which means that breaking changes can happen. Check out the status + roadmap in the docs. Maintained and developed by Ontola.io
