Historical place names

April 29, 2011

Improving the way GeoNames handles historical names is a popular feature request. GeoNames is now beginning to address this question.

There are two new flags in the alternate name edit tool:
isHistoric for names of the past that are no longer used.
isColloquial for slang and colloquial names

At the recent Annual Meeting of the Association of American Geographers is was discussed how GeoNames could be extended to improve support for the timeline. Some attributes under consideration:
– fromPeriod (date, year, decade, century or period of usage)
– toPeriod
– source (book or map where the name is used), publication date of the source
– notes

The discussion for these fields is still ongoing and any feedback is welcome.
The two new flags isColloquial and isHistoric are not yet included in the daily extract as we will probably add some more attributes and don’t want to change the extract files too often. Each change in the extact files breaks the import scripts of users. We will extract the records with the two new flags in separate files as a temporary workaround till everything is stable.
