Ontologies
An ontology (or vocabulary) is a formal definition of data types, properties, and conventions for particular domains of data. For example, if you list products on the web, then you may be familiar with schema.org/Product as a method for describing products with a name, weight, pricing, and many other properties.
Any vocabulary can be referenced within data sources, but we offer some additional integrations and documentation for the following, well-known vocabularies.
