we can get temporal info on Place through list of Arachne identifieres in Gazetteer data
there is sometimes a list of identifiers on Gazetteer data. among those identifiers are (sometimes multiple) identifiers for Arachne data sets. the identifiers in Gazetteer are typed. but they are not reliably present. on the other hand also searches for linked objects in Arachne are not reliable. i.e. https://gazetteer.dainst.org/app/#!/show/2767491 references Arachne Entities through identifiers; but a search for linked objects in Arachne does not give results. the question is still unanswered if it is sufficient to find the topography mirroring the Gazetteer data to look for dating information, since often dating information is not present. in that case it is good to be flexible to fetch other types of objects to gather dating info from them.
