Data

Updates

All of the data in API and corresponding GitHub repository, collectively referred to here as the "dataset", is updated via automated process daily directly from our central collection content management system (CCMS). Any changes in the CCMS will be reflected upon this update in the dataset.

As part of this update, the data in the CCMS is analyzed to account for any new artworks or new information in an artwork record that would necessitate a change to the share_license_status field.

This field will have values of "CC0", "Copyrighted", or "Other". While all data in the dataset is released with a CC0 designation, only artworks with the CC0 share_license_status will additionally provide access to CC0 images.

These automated updates are generally completed by 5am daily.

cc0 none Filters by works that have share license cc0.
copyrighted none Filters by works that have some sort of copyright.
department string Filter by department. List of valid departments in Appendix B.
type string Filter by artwork types. List of valid types in Appendix C.
has_image integer 0 or 1. Filter to return only artworks that have a web image asset. (synonymous with the deprecated field web_image)
indent integer Number of spaces to indent JSON content if "pretty" formatting is desired.
skip integer Offset index for results.
limit integer Limit for number of results. If no limit provided, API will return the maximum (1000) number of records.
updated_since ISO-8601 date string Return artworks updated since date string (represented in ISO-8601 format). eg:
updated_since=2022-01-01

Advanced Search Fields

Name Type Description
artists string Filter by name of artist.
title string Filter by title of artwork.
technique string Filter by artwork technique, i.e. materials of creation. For example, "wood carving" or "glass beads"
medium string Filter by artwork technique, i.e. materials of creation. For example, "wood carving" or "glass beads".
Alias for "technique".
dimensions float,float,float Filter artworks by dimensions with the unit of measurement being meters. This filter is somewhat tricky, as the terminolgy for describing object dimensions varies from object to object (for example coins have diameters, swords have lengths, and necklaces have heights). An object's most descriptive dimension (whatever you think is the best way to describe it in meters) is generally put in the first part of the comma seperated list of dimensions. A default value of 20cm will be used if no value is provided for a dimension in the list. The second and third dimensions places are interchangable and describe a square that an object's remaining dimensions could fit inside. The dimensions filter returns objects with a fault tolerance of 20cm on all dimensions.
dimensions_max float,float,float Filter artworks to return all works that can fit inside a box defined by provided 3 values with the unit of measurement being meters. Place the most descriptive dimension in the first value, and any remaining dimensions in the second two values. If no value is provided for a dimension, a default value of 20cm is used. The dimensions_max filter has a fault tolerance of 0 on all dimensions, and will not return objects that cannot fit in the described box.
dimensions_min float,float,float Filter artworks to return all works that cannot fit inside a box defined by provided 3 values with the unit of measurement being meters. Place the most descriptive dimension in the first value, and any remaining dimensions in the second two values. If no value is provided for a dimension, a default value of 20cm is used. The dimensions_min filter has a fault tolerance of 0 on all dimensions, and will not return objects that can fit in the described box.
credit string Filter by credit line.
catalogue_raisonne string Filter by catalogue raisonne.
provenance string Filter by provenance of artwork

   "description": "This album of landscape paintings depicts the famous scenic areas located in and around the city of Wuxing in southeastern China. The artist, Song Xu, was not a native of that city, but must have visited it when he accepted the commission, for he carefully depicted all eighteen views and wrote comments on each of them. These places were all known for their natural beauty, but in addition, a number were distingusihed by their links to eminent historical figures and events. Unlike other artists of his time, Song Xu favored a painting style that was technically polished and focused attention on specific, realistic details. Such an approach was well suited to projects like this one, for which the artist was in great demand.",

Despite its biblical source, this work was meant for a domestic setting, whose owner would have admired the artful presentation of a shocking story. Acquired in 1953 as the work of the Venetian Renaissance artist Titian, the painting soon lost this attribution because it lacks Titian\u2019s distinctive brushwork. After decades of research, the museum has yet to identify a clear author. Recently, several scholars have argued persuasively for a Spanish artist, partly because the subject is common in Spanish art in the early 1600s.

   "description": "William E. Smith (American, 1913-1997)",
   "biography": "A highly skilled printmaker, William Elijah Smith specialized in genre scenes of working-class African-American life in Cleveland. Born in Chattanooga, Smith moved to Cleveland at the age of 13 and became involved with Karamu House, learning print making and stage design. He studied art at the Huntington Polytechnic Institute, 1933\u201334. During this time he began teaching at Karamu House and continued to do so until 1940. In 1941 he won the art competition for presenting one of his prints to the Library of Congress for its permanent collection. Smith exhibited at the Connecticut Academy of Fine Arts in Hartford (1935), in the annual May Shows at the Cleveland Museum of Art (1936\u2013 49), at the Associated American Artists Galleries of New York (1942), and at Atlanta University (1942). During World War II, he served as a photographer in the army\u2019s educational department. After the war, he returned to Cleveland and established a commercial silkscreening studio. In 1946 the Lyman Brothers\u2019 Gallery in Indianapolis mounted his first solo exhibition. From 1946 to 1948 he studied painting and printmaking at the Cleveland School of Art and the Cooper School of Art. In the late 1940s Smith moved to Los Angeles, where he associated with Curtis Tann, a former colleague from Karamu House. With Tann, Smith cofounded the Eleven Associated Artists Gallery, the first Los Angeles gallery devoted specifically to African art. In 1952 Smith was hired to work as a blueprint draftsman at Lockheed Aircraft, beginning a long association with the corporation. In 1960 he cofounded Art West Associated, an African-American artists\u2019 advocacy organization in Los Angeles. In 1970 he published illustrations of subjects from African-American history for Cleveland\u2019s New Day Press. Smith\u2019 s works were displayed ins numerous group exhibitions in the Los Angeles area (1960s\u201380s).

  "description": "William E. Smith (American, 1913\u20131997)",
  "biography": "A highly skilled printmaker, William Elijah Smith specialized in genre scenes of working-class African-American life in Cleveland. Born in Chattanooga, Smith moved to Cleveland at the age of 13 and became involved with Karamu House, learning print making and stage design. He studied art at the Huntington Polytechnic Institute, 1933\u201334. During this time he began teaching at Karamu House and continued to do so until 1940. In 1941 he won the art competition for presenting one of his prints to the Library of Congress for its permanent collection. Smith exhibited at the Connecticut Academy of Fine Arts in Hartford (1935), in the annual May Shows at the Cleveland Museum of Art (1936\u2013 49), at the Associated American Artists Galleries of New York (1942), and at Atlanta University (1942). During World War II, he served as a photographer in the army\u2019s educational department. After the war, he returned to Cleveland and established a commercial silkscreening studio. In 1946 the Lyman Brothers\u2019 Gallery in Indianapolis mounted his first solo exhibition. From 1946 to 1948 he studied painting and printmaking at the Cleveland School of Art and the Cooper School of Art. In the late 1940s Smith moved to Los Angeles, where he associated with Curtis Tann, a former colleague from Karamu House. With Tann, Smith cofounded the Eleven Associated Artists Gallery, the first Los Angeles gallery devoted specifically to African art. In 1952 Smith was hired to work as a blueprint draftsman at Lockheed Aircraft, beginning a long association with the corporation. In 1960 he cofounded Art West Associated, an African-American artists\u2019 advocacy organization in Los Angeles. In 1970 he published illustrations of subjects from African-American history for Cleveland\u2019s New Day Press. Smith\u2019 s works were displayed ins numerous group exhibitions in the Los Angeles area (1960s\u201380s).

Collection Online Endpoints

In addition to the RESTful endpoints above, there are 3 additional endpoints that are used by the CMA Collection Online to link directly to data and images in certain formats for CC0-designated artworks. Strictly speaking, these endpoints weren't intended to be used independently of the Collection Online, but are included here for completeness.

GET JPEG and Caption

Return the print- and web-resolution images, as well as a text file containing the caption or "tombstone" information for the artwork. This is accomplished by pulling the tombstone and image urls directly from the API database, writing them to a zipfile, and returning it in the API response.

Example Request

https://openaccess-api.clevelandart.org/api/collectiononline/jpeg_and_caption/1974.1

GET High-Resolution TIFF

Return the high-resolution TIFF of the artwork. This simply redirects the user to the TIFF location in the CDN.

Example Request

https://openaccess-api.clevelandart.org/api/collectiononline/tiff/1974.1

GET Metadata Only

Return a formatted plain-text file with all the API data for the artwork. This is accomplished by pulling all artwork data directly from the API database, putting it into human-readable format via a Jinja template, and returning as a text-file.

Example Request

https://openaccess-api.clevelandart.org/api/collectiononline/metadata/1974.1

Appendix D: Code Examples

The following are some basic examples in Python, Ruby, Node.js, and Go for querying the CMA Open Access API and printing a list of artwork tombstone and image information. In each example, the code grabs the first 10 artworks that match the keyword "monet".

Python

import json
import requests


def print_openaccess_results(keyword, skip=0, limit=100):
    url = "https://openaccess-api.clevelandart.org/api/artworks"
    params = {
            'q': keyword,
            'skip': skip,
            'limit': limit,
            'has_image': 1
        }

    r = requests.get(url, params=params)

    data = r.json()

    for artwork in data['data']:
        tombstone = artwork['tombstone']
        image = artwork['images']['web']['url']

        print(f"{tombstone}\n{image}\n---")

if __name__ == '__main__':
    print_openaccess_results("monet", 0, 10)

Ruby

require 'net/http'
require 'json'


def print_openaccess_results(keyword, skip, limit)
    uri = URI("https://openaccess-api.clevelandart.org/api/artworks")
    params = {
        :q => keyword,
        :skip => skip,
        :limit => limit,
        :has_image => 1
    }

    uri.query = URI.encode_www_form(params)

    resp = Net::HTTP.get_response(uri)

    JSON.parse(resp.body)['data'].each do |artwork|
        tombstone = artwork['tombstone']
        image = artwork['images']['web']['url']

        puts "#{tombstone}\n#{image}\n---"
    end
end

print_openaccess_results "monet", 0, 10

Node.js

const axios = require("axios");


const printOpenAccessResults = (keyword, skip, limit) => {
    const url = "https://openaccess-api.clevelandart.org/api/artworks"
    const params = {
            q: keyword,
            skip: skip,
            limit: limit,
            has_image: 1
        };

    const resp = axios(url, {params})
        .then((resp) => {
            for (const artwork of resp.data.data) {
                const tombstone = artwork.tombstone;
                const image = artwork.images.web.url;

                console.log(`${tombstone}\n${image}\n---`);
            }
        })
        .catch((e) => {
            console.log("ERROR getting artwork data");
            console.log(e);
        });
}

printOpenAccessResults("monet", 0, 10);

Appendix E: Image Similarity Search Code Example

Below is a simple Python code example demonstrating how to use the image similarity search functionality in the API.

import requests, json

def post_a_file(filepath, params={}):
    url = "https://openaccess-api.clevelandart.org/api/artworks"
    
    with open(filepath, 'rb') as f:
        file_data = {
            'file': f
        }
        r = requests.post(url, data=params, files=file_data)
    
    data = r.json()
    return data

def get_similar_images(filepath):
    data = post_a_file(filepath)
    
    for artwork in data['data']:
        print(artwork['accession_number'])
        print(artwork['images']['web']['url'])

if __name__ == '__main__':
    filepath = '/home/user/you_image.jpg' # replace with your file path
    
    get_similar_images(filepath)
