This European Prestandard specifies a set of representational primitives and semantic relations required for an unambiguous representation of explicit time-related expressions in medical informatics. This Prestandard 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 Prestandard 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.
