Creative Commons + is not a new Creative Commons licence, but a new protocol that can let you add more permissions beyond any standard CC licenses.
Worth emphasizing is that CC+ requires that the work be licensed under a standard CC license ,that provides a baseline set of permissions that have not been modified or customized, but reproduces the verbatim license. The “plus” (+) signifies that all of those same permissions are granted on another separate and independent license agreement.
By using Creative Commons +, a composer in effect says, “Sure I’ve licensed this content in a way that closes some doors, but I could give you the key under certain circumstances. If you’re interested, here’s how you can get the key.”
Creative Commons + is a smart way to protect the creativity of those who aren’t yet ready to commit to alternatives to “all right reserved”. Let’s see it in details with few examples to make more sense:
The goal for many musicians is to make money from sales of their music. Many of them also loves sharing works for free. With a CC BY-NC-ND, license users are allowed to download these works for free as long as they don’t make money from it, don’t remix in any way and attributes the work to the composer. With a Creative Commons + license composers can allow user who pay fees to use a work protected by any existing CC license. That can let composers earn money also for works shared for free.
But Creative Commons + can also works very well for freelancers:
A videomaker posts a video on his blog and decide to protect it with a CC license that allows users to freely download his work as long as they attribute the work to him and not for commercial use.
He can also let the users know that anyone can request a license to use his work for commercial purposes: all anyone has to do is to email him, and he’ll decided on a case-by-case basics. To facilitate that conversation, he uses Creative Commons + by inserting a link to a “more permissions” link when licensing the video–in this case, a link to the “contact” section of his professional website, which instructs people simply to email him with licensing questions. A publisher finds this video on the videomaker’s blog and wants to use it for a commercial; the publisher follows the Creative Commons + link to the page with instructions on how to proceed.
So Creative Commons + can be a smart way to protect creative works while still leaving an interesting profit margin.
