The Data Commons Graph aggregates data from many different data sources into a single database. Data Commons is based on the data model used by schema.org; for more information, see the guide to the data model.
The Data Commons API allows developers to programmatically access the data in Data Commons. Data Commons provides several different ways to access its API’s resources:
- A REST API that can be used on the command line as well as in any language with an HTTP library.
- A lightweight Python wrapper.
- A heavier Pandas wrapper.
- A convenient Google Sheets add-on.
The endpoints can be roughly grouped into four categories.
Local Node Exploration: Given a set of nodes, explore the graph around those nodes.
Domain specific APIs: These are groups of APIs, specific to particular domains.
Graph Query/SPARQL: Given a subgraph where some of the nodes are variables, retrieve possible matches. This corresponds to a subset of the graph query language SPARQL.
Utilities: These are Python notebook specific APIs for helping with Pandas DataFrames, etc.
Most of the provided endpoints take references to nodes and properties as arguments. Every
node or property has a
Data Commons ID (DCID), which is used
to pass nodes as arguments to API calls.
Note: The DCID of schema.org terms used in Data Commons is their schema.org ID.
