Hypermedia and unicorns are so 2011! The next evolution in APIs on the web may well be linked data. With the recent adoption of json-ld by Google, we may finally be seeing the semantic web break into our world, bringing the benefits of graphs of semantic data to your APIs. We will discover, by visiting a magical world, what resources are, how we can describe them, and how they relate to one another. Don't be afraid, you will discover many mythical creatures, from resources and tuples to json-ld, hydra, and maybe even a sprinkle of RDF. So come feed the links!
