Datos Abiertos Vinculados

The American Art Collaborative Linked Open Data Consortium

The American Art Collaborative (AAC) is a consortium of fourteen U.S. institutions—thirteen museums and one archive--working together to create a critical mass of Linked Open Data (LOD) around the subject of the visual arts in America.

The National Portrait Gallery has been a member of the AAC since the consortium’s formal establishment in 2014. For a full list of participating institutions, educational briefings, presentations, and general project background, visit AmericanArtCollaborative.org.

Thanks to generous support from the Andrew W. Mellon Foundation and a leadership grant from the Institute of Museum and Library Services, the AAC has converted over 230,000 museum object records to LOD.

View the Browse Application Prototype

To design and develop a usable application for exploring the collected data, the project established a Browse Working Group, involving six of the 14 institutions and led by Design for Context, who developed a demonstration application, available at browse.americanartcollaborative.org.

The site allows objects and artists from across the 14 partner institutions to be explored through one interface. This application is a prototype, and is not meant to represent all the things that can be done with museum data in the future. Rather, it provides easy access to the available partner information and focuses on a few straightforward ways that data from the different institutions can be connected and explored.

Using the AAC Data

The URI construction for SPARQL queries is data.americanartcollaborative.org/sparql. We invite developers to make use of this data in their applications and share their results with us. 

Connect to the Portrait Gallery’s artwork data using this URI schema: data.americanartcollaborative.org/npg/object/id/[object_number] Examplehttp://data.americanartcollaborative.org/page/npg/object/id/18133

AAC Next Steps

As a next step, the AAC is seeking additional funding to expand the application of LOD within the museum and archival communities. As more museums produce LOD, we hope they will contact us, dialogue will ensue, and opportunities will increase to link or interconnect data and further demonstrate the value of LOD.
