Open source document management (alternative to Microsoft Sharepoint)

Question

I am looking for a open source application which will replace Microsoft Sharepoint.

Requirements:

• Open source
• Document management and storage system
• Revision history of all the files

Answer 1

Alfresco is an open source document management system.

It is rather similar to Sharepoint.

Alfresco is easier to use by office workers than Subversion, especially because it does not have branches (Sharepoint also does not have branches).

Answer 2

I have used Subversion in industry for many years for version control of documents. There may be something better, but SVN is free and it lets us keep the documents with the code. Go for it.
