AiiDA support the automatic import and export of atomic structures from and to selected external databases.
The base class that defines the API for the importers can be found here: :py~aiida.tools.dbimporters.baseclasses.DbImporter.
Below is a list of available plugins:
dbimporters/icsd dbimporters/cod
In general terms, the export to external databases can be viewed as a subworkflow, taking data as input and resulting in the deposition of it to external database(s).
Below is a list of supported databases with deposition routines described in comments-type style.
