Thread:Wording: (1)

Is the word "perpetuates" correct (also used in the the preamble) ?


 * e.g. If a libre puro resource is extended by incorporating CC-BY material and then released CC-BY (as required), the freedoms are retained for this one step, but the next derived work in that line may be released in a more restrictive manner (e.g. CC-BY-NC - as allowed by its new license CC-BY).

If not, what would be a better word? (please add/comment)


 * retains
 * extends
 * includes
 * upholds
 * grants
