Aaron Bradley started out as a technical services librarian, took an interest in records and coding standards, and spent a decade designing websites. In the mid-2000s he pivoted to search engine marketing, became increasingly exposed to the world of linked data, and as a semantically-minded SEO viewed the 2012 release of the Google Knowledge Graph with more than casual interest. He is now helping to build EA’s knowledge graph and to facilitate the growth of an intelligent content ecosystem. His day-to-day work revolves around taxonomies, ontologies, content models and the linked data standards that support them.
