Comentarios
Un término se almacena como un objeto de TermSetItem en el objeto TermStore . Se containsreferences a las partes que definen un término elemento establecido.
Un término puede reutilizarse de primarios diferentes. Puede tener propiedades personalizadas asociadas con él. Puede tener varios objetos de Label asociados para diferentes LCID.
Cuando la propiedad IsKeyword se establece en true, el Term representa una palabra clave. Una palabra clave no tiene elementos secundarios y se almacena en la palabra clave TermSet.
Inicializar una nueva instancia de esta clase mediante el método CreateTerm() , el método estático GetTerm , o mediante la obtención de un objeto TermCollection .
