Creating a working metadata template to be edited

@pvgenuchten and my self were discussing the possibility to provide to the users a working template that, when validated, has all green lights.

The required fields will have generic content such as "put here the name of your organization" but we should warn the users that even if the validation is ok it could be a false positive.

As a consequence, users should be sure to insert his/her own right information.
