Visual Works

Introduction

The Visual Work API is a method of getting access to descriptions of image content, such as the appearance of paintings and two-dimensional artworks, sculptures and three-dimensional artworks, or digital images. The Visual Work model is of average complexity with many familiar properties and patterns, plus several additions to describe the visual work's relationship to other entities.

For more information about the usage of Visual Work data, please see the Object Aboutness model description.

Property Definitions

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

Properties of Visual Works

Property Name Datatype Requirement Description
@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 visual work's representation can be dereferenced
type string Required The class for the visual work, which MUST be the value "VisualItem"
_label string Recommended A human readable label for the visual work, intended for developers
classified_as array Recommended An array of json objects, each of which is a classification of the visual work and MUST follow the requirements for Type
identified_by array Recommended An array of json objects, each of which is a name/title of the visual work and MUST follow the requirements for Name, or an identifier for the visual work and MUST follow the requirements for Identifier
referred_to_by array Optional An array of json objects, each of which is a human readable statement about the visual work and MUST follow the requirements for Statement
equivalent array Optional An array of json objects, each of which is a reference to an external identity and description of the current visual work
member_of array Optional An array of json objects, each of which is a Set that the current visual work is a member of and MUST follow the requirements for a reference to a Set
subject_of array Optional An array of json objects, each of which is a reference to a Textual Work, the content of which focuses on the current visual work, and MUST follow the requirements for a reference
attributed_by array Optional An array of json objects, each of which is a Relationship Assignment that relates the current visual work to another entity
dimension array Optional An array of json objects, each of which is a Dimension, such as abstract height or width, of the current visual work
part_of array Optional An array of json objects, each of which is a reference to another Visual Work or a Textual Work that the current visual work is a part of
conceptually_part_of array Optional An array of json objects, each of which is a reference to an Abstract Work that the current work is conceptually part of
about array Optional An array of json objects, each of which is a reference to another entity of any type, that this text is primarily about
represents array Optional An array of json objects, each of which is a reference to another entity of any type, that this visual work represents or depicts
represents_instance_of_type array Optional An array of json objects, each of which is a type of another entity that this visual work represents or depicts, but where the individual is not known and MUST follow the requirements for Type
subject_to array Optional An array of json objects, each of which is a Right that is held over the intellectual work
created_by json object Optional A json object representing the creation of the image, which follows the requirements for a Creation
used_for array Optional An array of json objects, each of which is a Publication Activity, which follows the requirements for an Activity

Incoming Properties

Visual 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 image content.

Property Name Source Endpoint Description
representation All Entities can be represented in visual content, in other words the content of an image that depicts them.
shows Physical Object A physical object can show visual content
digitally_shows Digital Object A digital object, similarly, can digitally show visual content

Example

The JSON for a Visual Work entry for a visual content of Miro's "The Farm" could be as below.

  • It has the Linked Art context document reference in @context
  • It self-documents its URI in id
  • It has a type of "VisualItem"
  • It has a _label with the value "Appearance of Miro's The Farm" for people reading the JSON
  • It is classified_as "Cubist", which has an id of "aat:300021495", which is in turn classified_as being a Style ("aat:300015646")
  • It is identified_by a Name, with the content "Appearance of The Farm"
  • It is referred_to_by a statement which ...
    • ... has content of "A brilliant amalgamation of an intense ..."
    • ... is classified_as a Description ("aat:300435416")
  • It represents a Place, Mont-roig del Camp
  • It represents_instance_of_type Tree ("aat:300132410"), meaning there is a tree depicted but the tree has no separate identity beyond the content
  • It was created_by a Creation which ...
    • ... was carried_out_by Miro
    • ... had a timespan of between "1921-01-01" and "1922-12-31"
