Open Access content (images, data, software, and documentation) is content that the CMA publishes digitally online, free of charge, and without copyright and licensing restrictions. For more information about Open Access, visit Creative Commons [3]website for an  overview.

At the Cleveland Museum of Art, Open Access means the public now has the ability to  share, collaborate, remix, and reuse images of many as 30,000 public- domain artworks from the CMA’s world-renowned collection of art for commercial and non-commercial purposes. In addition, portions of collections information (metadata) for more than 61,000 artworks, both in the public domain and those works with copyright or other restrictions, works are now available. 

Creative Commons, a non-profit organization based in the United States, makes legal tools to help entities like the CMA legally share knowledge and creativity to build a more accessible and innovative world. Among Creative Commons' key contributions are a suite of licenses and public domain designations, as well as a community of experts and practitioners who support open access initiatives. Learn more about Creative Commons [4].  

The CMA's Open Access initiative is offered under  Creative Commons Zero [5] (CC0).   CC0 is a public domain dedication tool that, when applied to content, relinquishes all copyright and related rights that the dedicator may have in a work. CC0 content may be used free-of-charge for both commercial and non-commercial purposes without the prior consent or permission of the CMA, including copying, modification, distribution or performance. The CMA uses CC0 for two categories of content. The first is content in which the CMA owns all rights, such as some of the content its employees create. The second is content that the CMA digitizes and reasonably believes is in the worldwide public domain.  

For information Creative Commons Zero, please consult Creative Commons  Summary [6],  FAQs [7]  and  Legal Text [8].  

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.

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 [1](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.

Please Note: Alternative views of artworks in the CMA’s permanent collection are taken for conservation purposes or other reasons. They are not available for download. Only the primary view that represents the artwork is available for download in JPEG and TIFF format.

Users can also access the CMA's collection data via a GitHub Repository [1]. 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.
