Narrative Annotation: Consider document updates (modified content)

[HermannKroll]

At the moment, we just import new documents into our database. We never update documents if a document is already present but has a modified content for instance.

Parameter in Loading Script --replace_existing

Suggestions:

• Receive input file with "new" or "modified" documents
• Identify existing documents in database
• Delete all existing documents (and all information about them in all tables). DELETE CASCADING
• Treat all documents as new documents and process them
