An offhand, only half-serious comment I made in the Creative Commons open education slack channel in response to a very worthy question from BCCampus’ Amanda Coolidge led to a new (?) metaphor to help explain the different open-licensing implications between collecting and redistributing a group of works with different open licenses versus actually remixing several works to form a new, derivative work: hereafter known as the TV dinner vs the smoothie.
A “TV dinner” open work is when one collects separate works together and redistributes that collection, but clearly separates each work and its attribution. In this case, one is not “remixing” works, but rather curating them and offering that curation to others. Like with real TV dinners, you can still consume each ingredient by itself because they are served with clear boundaries separating each. In an open-license TV dinner, each work maintains its separate license and the collection does not need to reconcile the different licenses because each work stands alone in the collection.
A “smoothie” open work is when one mixes together parts or the whole of one work with parts or wholes of other works to create a new, derivative work that includes material from many sources. Like with real smoothies, you can’t easily separate the different ingredients once they are blended together. In an open-license smoothie, one can only include works with mutually compatible open licenses and the open license of the full derivative work must be consistent with the licenses of all the included works, typically the most restrictive license.
To help illustrate the metaphor I created some (admittedly slapdash) illustrations, and with some input from Creative Commons’ Cable Green and Ryan Merkley and others, have refined them a bit and offer them here for others to use to help illustrate and explain these different situations. In case you were wondering and like to go meta, yes, these images are themselves smoothies, so I was careful to include only works with compatible copyright statuses and license the new derivative works with licenses that are consistent with all the works I used.

Feel free to download and retain/reuse/revise/remix/redistribute these images and/or the original Sketch file, as long as you adhere to the various open licenses of the materials. Let me know if I can help provide modifications or different formats for these works, and I’m always happy to hear if people find them useful or not.
