Open Access
The Cleveland Museum of Art is proud to be an open access institution, offering the public the ability to download, share, collaborate, remix, and reuse images of public-domain artworks from the museum’s collection, as well as metadata for the entire collection—all without asking permission. High-resolution images and data related to the CMA’s collection are made available under a Creative Commons Zero (CC0) designation.
What is Open Access?
Open access content (images, data, software, and documentation) is content that the CMA publishes digitally, free of charge, and without copyright and licensing restrictions. For more information about open access, visit the Creative Commons website for an overview. Images, data, software, and documentation offered with Creative Commons Zero can be used in any application, from art making, education, digital media projects, scholarly research, and publications to data science—all without fees or restriction.
Why Open Access?
Open access is a logical and exciting outgrowth of the CMA’s inclusive mission “to create transformative experiences through art, for the benefit of all the people forever.” The time is right to firmly bring our mission into the 21st century. With this move to open access, we have transformed not only access to the CMA’s collection but also its usability inside and outside the walls of our museum. By expanding access to the collection, we proudly contribute to best practices, both in the quality of images and the wealth of data we will release.

Frequently Asked Questions
Our open access initiative includes more than half of the museum’s collection. The exact number changes frequently as new works enter the public domain, and we update our open access collection every January. Visit the museum’s Collection Online for a current count of open access works.
Works designated as Creative Commons (CC0) do not require attribution or citation. Copyrighted content, content with proprietary rights, or content that is otherwise restricted for limited noncommercial, educational, and personal uses should be cited including the URL “www.clevelandart.org” in addition to all copyright and other proprietary notices contained on the materials. Citation of the CMA’s CC0 or restricted content does not imply endorsement by the CMA, nor does it grant permission to use the CMA’s trademarks without prior approval.
You may wish to cite images and data from the CMA’s collections for educational and scholarly or other publication purposes. Consult the CMA Collection Online or metadata associated with an object via the application programming interface (API) or data from the GitHub Repository for information that can be used for citations.
There are a variety of citation formats, but consider including the following:
Artist. Title. Date (year). Medium. Dimensions. The Cleveland Museum of Art. Credit Line. Accession Number. URL from www.clevelandart.org/
Please Note
A credit line features of the name of the individual or group who sourced or donated an artwork to the collection of the Cleveland Museum of Art.
An accession number is the CMA’s official inventory number of record that is an artwork’s unique identifier in the collection. This number is helpful for identifying a work, especially for study, research, and publication purposes.
- If the CMA has not yet created a digitized image or data of the artwork
- If the artwork is under copyright or has other restrictions from the artist, donor, or lender
- If the artwork is not fully owned by the CMA
Look for the icon with Creative Commons Zero (CC0) on CMA websites and affiliates, along with seeking out the designation embedded in the image or dataset as metadata.
When searching the CMA’s collection, you can filter for open access images:

Collection Online Art Detail Page
On the Collection Online, you may print the page as a PDF for reference and research purposes.
Additionally, images and metadata may be downloaded via the “download” button on the artwork page. Please note that while portions of metadata are available for every object in the CMA's collection through open access, image downloads are only available for CC0 artworks.

Users interested in access to portions of metadata dedicated to the public domain with CC0 can access over 61,000 records via the CMA’s public application program interface (API). No key or token is required for access. Documentation regarding fields, departments, and data types is available through the API as well. Portions of metadata are made available for all digital images of public domain artworks whose underlying work is in the public domain including a URL to corresponding image file. Artworks in the CMA’s collection which may have copyright or other restrictions have portions of metadata with CC0, but no image file is supplied by CMA due restrictions.
Users can also access the CMA's collection data via a GitHub Repository. Detailed documentation is available here along with the data formatted in .JSON and .CSV. Please note that the CMA does not support pull requests. Data is refreshed at a weekly rate, so please check often for the latest revisions.
CC0 CMA collection data and images are also available from Internet Archive, Wikimedia Commons, and Wikidata.
No. The CMA's images, data, software and documentation designated as CC0 will not be issued under separate or individual agreements. See our Terms and Conditions for more information.
The CMA would be grateful to receive a copy of your print publication reproducing open access images with Creative Commons Zero (CC0) images and data, but this is not a requirement.

Measuring Impact
Since launching our open access initiative, the CMA has been asking “how is open access making an impact?” In May 2020, in collaboration with local data science firm Pandata, the CMA launched its Live Virtual Dashboards, which update daily. Click through the tabs to see different data sets!
Half a Decade of Open Access
Five years ago, in January 2019, the CMA launched its Open Access initiative, which makes available to the public high-resolution images of more than half the artworks in our collection, completely free to view, use, remix, merchandize, and more.
Open Access in 3-D
In September 2019, the Cleveland Museum of Art extended its open access policy to three dimensional (3-D) images of public domain artworks from its collection. Works with available 3-D image files are linked to open access objects in the Cleveland Museum of Art’s Collection Online with the 3-D icon and can be viewed and downloaded via Sketchfab.
You can interact with the Wade Cup with Animated Script on the CMA’s Collection Online and Sketchfab page, or try it here!
