Introduction

The Provenance Activity API is a method of getting access to descriptions of ... The API is of higher than average complexity with many familiar properties and patterns, but also with a series of classes which convey parts of the higher level activity, each with their own unique properties.

Property Definitions

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

Properties of Provenance Activities

The top level Activity has the following properties.

Required Classification

In order to determine that the activity is a Provenance Activity, rather than a more general Event or Activity, which would follow the event API instead, the Activity MUST have a classified_as entry with an id of "http://vocab.getty.edu/aat/300055863".

{
  "@context": "https://linked.art/ns/v1/linked-art.json",
  "id": "https://linked.art/example/provenance/0",
  "type": "Activity",
  "_label": "Provenance Activity",
  "classified_as": [
    {
      "id": "http://vocab.getty.edu/aat/300055863",
      "type": "Type",
      "_label": "Provenance Activity"
    }

Incoming Properties

Provenance Activities do not have any incoming references in the current set of APIs, instead they link out to many different entities.

It is classified_as a "Provenance Entry", which has an id of "aat:300055863"
It is identified_by ...
- ... a Name, with the content "Purchase of Lot 0055a, Durer's St George and the Dragon"
- ... and an Identifier, with the content "0055a"
It has a timespan between "1820-03-09T00:00:00Z" and "1820-03-09T23:59:59Z"
It took_place_at London
It used_specific_object of the auction lot, a Set which would have the object as a member
It consists of two part entries:
- An Acquisition which ...
  - ... transferred_title_of the object,
  - ... transferred_title_from a Person called Simpson (the seller),
  - ... and transferred_title_to a Person called Adams (the buyer)
