Hydra simplifies the development of interoperable, hypermedia-driven Web APIs
Building Web APIs seems still more an art than a science. How can we build APIs such that generic clients can easily use them? And how do we build those clients? Current APIs heavily rely on out-of-band information such as human-readable documentation and API-specific SDKs. However, this only allows for very simple and brittle clients that are hardcoded against specific APIs. Hydra, in contrast, is a set of technologies that allow to design APIs in a different manner, in a way that enables smarter clients.
Hydra Core Vocabulary
Essential building blocks for machine-accessible Hypermedia APIs
There also exists a demo Web API featuring a simple issue tracker which allows you to play with Hydra directly in your web browser.
Linked Data Fragments
API and client designs to publish and query Linked Data at Web-scale
- HydraConsole: a generic API console for Hydra-powered Web APIs
- HydraBundle: a bundle for Symfony2 to create Web APIs based on Hydra
- Hydra demo application: the issue tracker demo (uses the HydraBundle)
- hydra-java: annotate your Java beans and serialize them as JSON-LD with Hydra
- HydraClient: a PHP client library to access Hydra-powered Web APIs
- JsonLD: a JSON-LD processor implemented in PHP
