This is a demo for the Vesta Gov4webtrees module.
This module uses an enhanced facts and events tab, displaying places with GOV (historical gazetteer) data relevant at the time of the event. See e.g. the default individual.
Currently, you have to enter the GOV ids manually, once for each place name (either outside GEDCOM code, as shown here, or within GEDCOM, e.g. via the Shared Places module). The GOV data is then retrieved via the GOV webservice interface and cached locally in additional webtrees tables.
Feel free to experiment with setting/resetting GOV Ids. Contact me for any suggestions or other feedback (via email or the webtrees forum).
