US2TS Conference position paper on publishing and retrieving not just LOD, but LOUD -- Linked Open Usable Data.

APIs are the UIs of Developers, and need:
* Correct Abstraction level for the Audience
* Few Barriers to Entry
* Comprehensible by introspection
* Thorough Documentation with copy-able examples
* Few Exceptions, instead consistent patterns

  16. 16. @azaroth42 rsanderson @getty.edu IIIF: Interoperabilituy Linked Open Usable Data @azaroth42 rsanderson @getty.edu Data Model and API? JSON-LD contexts and frames abstract the representation from the ontology, providing the necessary separation of concerns between data model and API to enable usability without compromising on semantics.
