The document discusses using ontologies and semantic technologies to enable knowledge sharing and interoperability across communities of interest. It describes applying a business centric methodology using classification schemes, taxonomies, templates and archetypes to connect business concepts to technical implementations. Specifically, it focuses on using these approaches to enable semantic interoperation in domains like e-health, by allowing standardized discovery, understanding and exchange of clinical records and other information across systems and organizations.
