      dcterms:abstract "The Health IT Ontology (HITO) allows systematically describing application systems and software products in health IT. Our motivation is that information management professionals have a strong need to share and compare knowledge about health IT in several situations. These situations are, among others, to describe the components of a health information system as part of its strategic or operational management, to select a new software product, to learn about available evidence regarding an application, or to hire or train health IT specialists."@en;
