Informal Description

The AlphLinkDocument type is a subclass of https://schema.org/CreativeWork. It's a JSON-LD document containing a collection of links in its @graph property. These links will predominantly be between documents and media fragments on the World Wide Web, but of course this being a Linked Data application, the links might represent abstract relationships between anything at all.

As the AlphLinkDocument SHOULD be valid JSON-LD, then it could be serialized into any other RDF serialization that a person wanted (such as Turtle, N-triples, etc.).
