Is a single article or blog post that contains, say three creative commons images, along with some text, considered a Collection
or Collective Work
? How about if the blog post contains a single creative common image along with some text?
CC BY-SA 2.0 says:
"Collective Work" means a work, such as a periodical issue, anthology or encyclopedia, in which the Work in its entirety in unmodified form, along with a number of other contributions, constituting separate and independent works in themselves, are assembled into a collective whole. A work that constitutes a Collective Work will not be considered a Derivative Work (as defined below) for the purposes of this License.
CC BY-SA 3.0 (which appears to drop the term "Collective Work" in favor of "Collection") says:
"Collection" means a collection of literary or artistic works, such as encyclopedias and anthologies, or performances, phonograms or broadcasts, or other works or subject matter other than works listed in Section 1(f) below, which, by reason of the selection and arrangement of their contents, constitute intellectual creations, in which the Work is included in its entirety in unmodified form along with one or more other contributions, each constituting separate and independent works in themselves, which together are assembled into a collective whole. A work that constitutes a Collection will not be considered an Adaptation (as defined below) for the purposes of this License.
CC BY-SA 4.0 appears to drop mention of collections.
