Web Ontology Language (OWL) is a computer language that people use to make statements about things on the internet. It is like the English language, but instead of using words to describe things, it uses symbols. OWL is used to describe things on the web like the animals in a zoo, the items in a store, and the countries in the world. It helps computers understand information in a way that humans can understand. OWL also helps computers remember things better, like which animals are in a zoo or what kind of store it is.
