OBO Foundry

The OBO Foundry is a group of websites that work together to create a public database of terms and definitions that can be used to explain different things. For example, if you want to know what an elephant is, you can look up its definition on the OBO Foundry. All of the websites in the OBO Foundry have a common set of rules for how to create and maintain the database, so you can use any of them and still have the same information.
