Open Source Document Management System | OpenKM

Hello Everyone,
I would like to implement a procedure that can be executed at need by any User to set the rights on a given document according to standard criteria.
Is Workflow the best option to obtain this functionality (even if no multiple management steps are required)? Are there examples of configuration and scripts that provide this type of result?
Many thanks,
Armando

Depending the criteria could be automatically in background. Other solution will be extend macro utilities ( but that need source changes )
and finally as you suggest other way could be ( under workflow logic ) really will be easy to do into workflow.

But depending the logic I should suggest one thing or other, for example if logic is based on folder or subfolder, document name or username then automation is your solution. If it's always on end user decision then is workflow or extending macros feature ( need source changes )
