Document Management Software for retrieval and accounting, with barcodes
I am looking for an idea about relevant software/frameworks/components for DOCUMENT MANAGEMENT. Should include handling of scanned documents with barcodes. The main purposes are retrieval and accounting.
Think there should be barcodes put on the documents before scanning. These codes should be represented in the filenames. Barcodes should also be put on binders, boxes etc. OCR as far as it can be done cheaply today.
(Expect OCR to be done/redone in the future)
In addition to scanned documents there are "native digital" documents like pdf invoices and bank data downloaded from online banking. It should be possible to connect this information internally and with scanned documents.
It should be possible to categorize and label scanned documents for future use.
I am looking for an open-source/low cost flexible software.
I.e. where I can access the data directly in Excel files or databases.
Technical preferences: SQL Server (free versions), .NET, Python, Open Source, Windows, Drupal.
