I gather from searching old forum posts that there are issues with Sampling Plus licencing compatibility, and this FAQ seems to indicate that it’s incompatible with other licenses, but there are tracks on CCMixter using samples from the Wired CD and the licence description sounds naively compatible with BY-NC. What’s going on? Is there any official statement or other information sources that I should be aware of? (Am not asking for legal advice, I just imagine that the people here would have had to findanswers to the same question…)

here are a couple of resources:

from the faq page of the Creative Commons Wiki a re-licensing compatibility matrix

a license compatibility wizard from CC Taiwan as mentioned on the main creative commons blog

hope that helps :-)

I’m not a lawyer, so you won’t get the legal advice you didn’t ask for. :)

My understanding is that because Sampling+ includes

Quote: Prohibition on advertising. All advertising and promotional uses are excluded from the above rights, except for advertisement and promotion of the Derivative Work(s) that You are creating from the Work and Yourself as the author thereof.

you couldn’t incorporate a Sampling+ work into a BY-NC work and pass along all of the freedoms BY-NC offers — Sampling+ could prohibit a promotional use that qualifies as not commercial.

I could well be wrong.
