This document specifies a set of representational primitives and semantic relations needed for an unambiguous representation of explicit time-related expressions in health informatics. This document does not introduce or force a specific ontology of time, nor does it force the use of a fixed representation scheme for such an ontology. Rather this document provides a set of principles for syntactic and semantic representation that allow the comparability of specific ontologies on time, and the exchange of time-related information that is expressed explicitly.<\/p>\n
This document applies to both the representation of actual phenomena occurring in the real world (e.g. registrations in medical records) and to the description of concepts (e.g. medical knowledge bases).<\/p>\n
This document is applicable to<\/p>\n
developers of medical information systems where there might be a need for explicit time-related concepts for internal organization (e.g. temporal data bases, temporal reasoning systems),<\/p>\n<\/li>\n
information modellers or knowledge engineers building models for the systems mentioned in a),<\/p>\n<\/li>\n
experts involved in the development of semantic standards on precise subdomains in health care where time-related information needs to be covered, (e.g. in the study of pathochronology, i.e. the discipline dealing with the time course of specific diseases), and<\/p>\n<\/li>\n
developers of interchange formats for messages in which time-related information is embedded.<\/p>\n<\/li>\n<\/ol>\n
This document is not intended to be used directly for<\/p>\n
representing what is true in time,<\/p>\n<\/li>\n
reasoning about time, or<\/p>\n<\/li>\n
representation of metrological time.<\/p>\n<\/li>\n<\/ul>\n
