-Often the models definition requires cross-system unique identifiers. So called OIDs or TIDs, what are represented in the physical database as the `t_ili_tid` column. Find a clear definition and more details about them in the [corresponding chapter](../../background_info/oid_tid_generator).

-If you need a counter in the expressions, you can use the `t_id` field, that has a schema-wide sequence counting up. This sequence can be reset as well by the user, but be careful not to set it lower than already existing `t_id`s in your project.

+If you have already selected a metaconfiguration file [previously](#metaconfiguration-topping) and this metaconfiguration file refers to a project topping file (`YAML` file containing the layer tree and links to the layer style files), it is taken into account by default. If you create the project from an existing database, Model Baker checks whether this schema was created with a meta configuration file to consider here. If this is not the case, or if you simply want to select a different file, this option is also available. Get your project topping file from the repositories or from your local system.
 
 ### Optimize QGIS Project if extended
 
 In case you gereate your project for an extended model structure that was created with *smart2inheritance*, then you can optimize it (hide or group unused layers and relations).
