Knowledge Graphs work by storing data in a RDF format, or a triple format which means there is a subject, predicate and object. If we were to take Legislate as an example, and the fact that Legislate is a company, to store this in a knowledge graph we would have “Legislate” as the subject, “a” as the predicate and “Company” as the object. As a RDF triple, the fact would look like “ :Legislate a :Company”. The colon is used to reference the prefix of where the data is stored, but can be quite complicated to understand and isn’t that important from an overview.
