AgeCategory is defined as "The age group of a health actor, e.g. old or young."@en The SAREF Core pattern for states can be used to model the AgeCategory. ``` s4ehaw:AgeCategory a saref:State . s4ehaw:Old a saref:State ; skos:broader s4ehaw:AgeCategory . s4ehaw:Young a saref:State ; skos:broader s4ehaw:AgeCategory . ``` And in practice: ``` <actor> saref:hasState s4ehaw:Old . ```
