How it works

When importing a document from a web source, a document is created with a field _draft:'true' to help the importing process. When the user doesn't go through with the import (cancelling or not saving the document), the draft is kept in the database with unvalidated data.

Improvement suggestion

Add a daily or weekly task that runs during the night and deletes all documents with _draft: true that are older than 24 hours.
