The Cleveland Museum of Art Open Access
The Cleveland Museum of Art (CMA) was founded in 1913 “for the benefit of all the people forever.”1 The museum strives to help the broadest possible audience understand and engage with the world’s great art. The Cleveland Museum of Art is one of the most comprehensive art museums in the world and one of northeastern Ohio’s principal civic and cultural institutions.
The Cleveland Museum of Art provides datasets of information on more than 61,000 artworks in its Collection for unrestricted commercial and noncommercial use. Additionally, the museum provides image assets for as many as 30,000 works, which are made availble under the same terms. Links to the web, print, and full-sized, uncompressed versions of these images are included in the dataset where applicable.

About the data
A full description of the fields available in the dataset can be found in the API documenation:
git LFS (large file storage)
Due to the large size of the JSON and CSV datasets requires the user to install the git LFS extension to pull the full files and not just the text pointers.
The extension, along with full documentation, can be found here.
After installing the extension, clone this repository and then execute
git lfs pull
