This is a Java implementation of the JSON-LD 1.0 specification and the JSON-LD-API 1.0 specification. The Options specified by the JSON-LD API Specification are accessible via the com.github.jsonldjava.core.JsonLdOptions class, and each JsonLdProcessor.

This is going to be a look at my philosophy and views on ActivityPub and why I believe the solutions to ActivityPub criticisms must come from communities. I believe there needs to be a clear way for communities to form and build upon the ActivityPub specification.

If you have data for which a digital signature was generated, you can verify the authenticity of the signature. To do so, you need In this example you write a VerSig program to verify the signature generated by the GenSig program.

A A mock ActivityPub server to use in testing code

Frameworks Bonfire: An extensible framework with a big focus on customisation and flexibility. Can be used to build new federated apps while focusing on a specific use case rather than reimplementing lots of boilerplate AGPL-3.
