Public resources compatible with Knowledge Graphs

In many industries there are shared models that are important for day-to-day work. In a growing number of cases, these models are being formalized as ontologies and other formats that are compatible with knowledge graphs. Other large models are focused on a more global view of knowledge.

Some examples of notable public graphs/models are listed below. Follow this link to more information about using knowledge graphs in Tag.
