The FT maintains an ontology which provides a structure for all the concepts we need to write or reason about.
Any concept can be referenced by a unique URL. For example, the FT's URL is http://www.ft.com/thing/73cc33b5-d0cb-3815-8347-bc49e1ddbd5c
Following the principles of the Semantic Web, you can visit these URLs in a browser to learn what a concept is and which other concepts it is connected to.
If you are interested in developing products which use FT ontologies, instance data or content, please visit our site for developers.
