Data Commons is an open-source platform[1] created by Google[2] that provides an open knowledge graph, combining economic, scientific and other public datasets into a unified view.

[3] Ramanathan V. Guha, a creator of web standards including RDF,[4] RSS, and Schema.org,[5] founded the project,[6] which is now led by Prem Ramaswami.

[11] The service expanded during 2019 to include an RDF-style knowledge graph populated from a number of largely statistical open datasets.

It includes geographical, demographic, weather and real estate data alongside other categories,[3] describing states, Congressional districts, and cities in the United States as well as biological specimens, power plants, and elements of the human genome via the Encyclopedia of DNA Elements (ENCODE) project.

The graph can be accessed through a browser interface and several APIs,[3][11] and is expanded through loading data (typically CSV and MCF-based templates).
