In this tutorial, we’ll learn how to transform a Java Object to JSON-LD and vice versa. Also learn how to verify the schema of JSON-LD. JSON-LD is a JSON-based format which is used to represent structured data and linked data. Schema of JSON-LD can be found in documentation of schema.org.
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.
Java 16 introduces Records. While this version of records is fantastic, it's currently missing some important features normally found in data classes: a builder and "with"ers. This project is an annotation processor that creates: Hat tip to Benji Weber for the Withers idea.
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.
Today we’ll be looking at how to connect the protocols powering Mastodon in the simplest way possible to enter the federated network.
Recently I contributed an addition to the Bookwyrm social reading software to enable "remote following". Bookwyrm uses the ActivityPub protocol for decentralised online social interaction.
Testing asynchronous systems is hard. Not only does it require handling threads, timeouts and concurrency issues, but the intent of the test code can be obscured by all these details.
