Even if there is no specific death date mentioned in the source, it is recommended to provide a Death event and estimate the dates based on other (life) events around the person. A concrete example would be the mentioning of a Burial event, by which the death date can be estimated, for instance by setting the `sem:hasEarliestBeginTimeStamp` property to the date of the Burial event. Example: ```ttl _:person1 a roar:PersonReconstruction ; rdfs:label "Susanna de Bock" ; pnv:hasName [ a pnv:PersonName ; pnv:baseSurname "Bock" ; pnv:givenName "Susanna" ; pnv:literalName "Susanna de Bock" ; pnv:surnamePrefix "de" ] ; bio:event [ a bio:Burial ; bio:place _:location1 ; bio:principal _:person1 ; sem:hasActor [ a sem:Role ; sem:roleType [ a sem:RoleType ; rdfs:label "burried" ] ; rdf:value _:person1 ] ; sem:hasTimeStamp "1697-02-28"^^xsd:date ] ; bio:birth [ a bio:Birth ; bio:principal _:person1 ; sem:hasActor [ a sem:Role ; sem:roleType [ a sem:RoleType ; rdfs:label "born" ] ; rdf:value _:person1 ] ; sem:hasLatestEndTimeStamp "1697-02-28" ] ; bio:death [ a bio:Death ; bio:principal _:person1 ; sem:hasActor [ a sem:Role ; sem:roleType [ a sem:RoleType ; rdfs:label "died" ] ; rdf:value _:person1 ] ; sem:hasEarliestBeginTimeStamp "1697-02-21" ; # Estimated, 7 days earlier sem:hasLatestEndTimeStamp "1697-02-28" ] ; roar:documentedIn _:saaId10160347 . ```
