This document discusses making linked open data usable. It advocates for publishing and retrieving linked open data through application programming interfaces (APIs) that have the right abstraction level, few barriers to entry, are comprehensible through introspection, and follow consistent patterns. JSON-LD is recommended for expressing linked data through APIs because it separates the data model from the representation using contexts and frames. This allows for usability without compromising semantics. The document also recommends focusing on solving real challenges with available data that meets requirements, and designing data to be reusable by others.
