Linked Art API: Abstract Work

Table of Contents

Introduction

The Abstract Work API is a method of getting access to descriptions of abstract or conceptual works and especially when those works are instantiated by activities rather than physical or digital objects. Examples are the "idea" behind an exhibition, the general concept of a piece of performance art rather than the activity which enacts that idea, or the most general form of a work without specifically being composed of image or language. Abstract works are thus not frequently used but are necessary to connect instances of the work, such as a travelling exhibition or different performances of the same idea.

For more information about the usage of Abstract Work, please see the Document model description.

Property Definitions

Dereferencing an entity via the Abstract Work endpoint would result in a JSON-LD document containing a single JSON object with the following properties.

Properties of Textual Works

@context string, array Required The value MUST be the URI of the Linked Art context as a string, "https://linked.art/ns/v1/linked-art.json" or an array in which the URI is the last entry to allow for extensions
id string Required The value MUST be the HTTP(S) URI at which the work's representation can be dereferenced
type string Required The class for the work, which MUST be the value "PropositionalObject"
_label string Recommended A human readable label for the work, intended for developers

Incoming Properties

Abstract Work instances are typically found as the object of the following properties, other than the self-referential properties above. This list is not exhaustive, but is intended to cover the likely cases where other endpoints refer to texts.

Property Name Source Endpoint Description
about Textual Work Textual works can be about abstract works
influenced_by Activity Activities (such as Exhibitions) can be influenced by the abstract work

Example

The JSON for an Abstract Work entry for the idea for an exhibition about Gainsborough could be as below.
