The place name database is a separate, independent, additional database from this list. Each entry in this place name database contains the following fields:
| Field | Contents |
|---|---|
| name | Unique name of the place |
| GOV-ID | Location identifier in GOV |
| Coordinates | Longitude and latitude coordinates of the location on Earth |
| abbreviation | Abbreviation for the location |
For each location in a card index, Omega searches for a corresponding location in the place name database. Therefore, the place names in the card index and in the place name database must be unique and identical. Different places with the same name must be distinguished in the card index and in the place name database by additional information (example: Neunkirchen and Neunkirchen/Nahe ).
Each card index has its own location database. It is planned that in later versions several card indexes will share a location database or that records will be transferable from one location database to another.
Note: Please be aware that we are therefore dealing with a total of three independent databases:
The first two are linked via the place name and the last two via the GOV ID.
