We are just learning about using a DMS. We will be moving to Alfresco Community but before we did I wanted to be sure we had a good file naming scheme. I guess I was missing the point. The search ability in the DMS makes the need for a naming scheme unnecessary.
ich you already have a naming-scheme you can use it for the automatic-classification of your files when they get imported in Alfresco. You can create a rule (like the rules in Mail-Clients or Servers) that triggers when a file is uploaded to a folder, grab the name of the file and add Metadata to it (i.e. if document.name starts with INV, it's an invoice...)
