RDF graphs are good for modelling different components and utilizing the relationships and connections they have with each other. RDF graphs use all of this information to create a metadata layer that helps determine whether different names indicate the same item, whether the items are related, and even indicate whether different items can be used interchangeably because of their similarities. This is used in the pharmaceutical world as well, for identifying different chemicals, medicines, and generic names.

Without an RDF graph, applications usually embed logic to help find the correct items. But this logic doesn’t always work across all databases, as each one often has different naming conventions. And if the DBA who created that application logic leaves the company, then the logic often gets lost.
