The main advantages of authoring an olog rather than writinga prose descriptionof a subject are that•an olog gives a precise formulation of a conceptual world-view,•an olog can be formulaically converted into a database schema,•an olog can be extended as new information is obtained,•an olog written by one author can be easily and precisely referenced byothers,•an olog can be input into a computer and “meaningfully stored”, and•different ologs can be compared by functors, which in turn generate auto-matic terminology translation systems.
