There are a batch of olld railroad stations in the middle parts of Sweden, now I can just delete them but they maybe interesting in a historical sense. What should I do?
date attributes are missing so far in the GeoNames data model. It is not yet possible to model changes of features over time.
I cannot say whether it is better to keep them or not, normally I would say they should be deleted. Unless they continue to have some kind of landmark function.
Yes it is possible to undelete, nothing is physically deleted. It is just flaged as deleted. What is still missing, however, is a search and display function for deleted features.
