The first import of the organizations should be performed using the sql script: first_import_grid_ac.sql
1) Download the last dump from https://www.grid.ac
2) Update the paths in the sql script
3) Launch the script
If you want to add missing ROR identifiers:
1) Download ror.json from https://figshare.com/collections/ROR_Data/4596503
2) Update the paths in prepare_grid_ror_update.pl and update_ror_ids.sql
3) Launch prepare_grid_ror_update.pl
4) Launch update_ror_ids.sql
NB: The grid.ac dump is richer then ror dump, Ror does not consider some fiels (city, lat, lng) and hierarchical relationships among the organizations.
If grid.ac will be DEPRACATED we'll start using the import from ror (a script is available: prepare_import_ror.pl)
