>       o It is correct that the PROV-N uses the production timeOrMarker
>         to encode time information in PROV-N and does not specify what
>         generation time means.
>       o It is the purpose of the prov-dm document to define what is
>         meant by generation time.
>       o We refrained from repeating such definition in the prov-n
>         document, to avoid potential inconsistencies between normative
>         documents.
>       o Instead the production generationExpression is followed by a
>         table, mapping prov-n arguments to the corresponding prov-dm
>         attributes, as defined in the prov-dm document.
>       o For instance, timeOrMarker is mapped to time, defined in
>         prov-dm as/time: an optional "generation time" (t), the time
>         at which the entity was completely created;/
