DataBaseRegister¶

class data_base.data_base_register.DataBaseRegister(registry_basedir, search_dbs='on_first_init')¶

Two column registry mapping data bases to their locations.

This registry keeps track of all DataBase id tags and their locations on disk. This is useful when sharing data with other people, resolving relative database paths, and moving databases to other file systems. This registry implements an SQLite backend to store these locations and corresponding database IDs.

You can explicitly walk through a directory and add all DataBase it encounters to the registry with DataBaseRegister.search_dbs().

Parameters:¶

registry_basedir : str¶

The location of the db registry

search_dbs : str|bool, optional¶
