Caption for a figure reproduced from a CC-licensed document In a research paper for a journal, which uses Science magazine publication style, I'm reproducing a diagram from a document, which has a Creative Commons (CC)-based open document license. The diagram (figure) itself doesn't contain any license references, as is typical for most CC-licensed figures, however the whole original document contains the following statement:


  This work is made available under the terms of the Creative Commons
  Attribution-NonCommercial 3.0 Unported License,
  creativecommons.org/licenses/by-nc/3.0/.




Question: What should be the content and style of the borrowed figure's caption, considering the journal style and the document license? In other words, should it just be (X is reference number)


  Figure 1. The title of the figure. Reproduced from Reference X.


or


  Figure 1. The title of the figure. Reproduced from Reference X (CC BY-NC 3.0).


or something else?
Including the license terms in the figure caption isn't necessary.  "Attribution" in CC licensing is usually interpreted as "provides name of author and/or source of original", which you do fine with just "Reference X".

EDIT from comments: As pointed out by @ff524, the CC guidelines suggest including license terms. It makes sense to include title, author name, source, license in the reference section.  Not necessary for the image caption though.
