Are there any official, generic guide lines when it comes to retention of information stored in the database and the documentation stored in knowledge centers (when to archive, eliminate, how to handle such situation)?
It's obvious we'd have to tailor it to our specific application but I wanted to start by observing any suggestions given by Appian.
Best Regards.

I do not know of any best practices. In the end, you will have to store the date when to handle deletion for each document or record. Then schedule a cleanup process that manages the required tasks.
This is as close as you'll get: docs.appian.com/.../Archiving_Processes.html
Data retention rules are usually primarily dictated by the organisation itself and sometimes by technical / costing considerations (i.e. price of disk space).
For documents specifically, I would generally advise on moving them to a CMS at some point in their lifecycle.
