Is a research paper on OSM a derived work?

In a long an insightful blog post on Google MapMaker's US launch Mike Dobson mentions a paper by Girres and Touya. According to his blog this paper uses a similar approach to that of Muki Hakaly to analyse French OSM data. I'd like to read this paper, and consider its implications : after all I've contributed to the data that it has used. However it lies behind a pay-wall here: Girres, J.F. and, Touya, G. (2010). Quality Assessment of the French OpenStreetMap Dataset, Transactions in GIS 12(4), 435-459.

I didn't find an electronic offprints at the researchers lab site: IGN COGIT. If anyone knows where I can get a copy let me know.

I would regard it as a normal courtesy of scientific publication to give contributors access to paper based on their data. Certainly the derived data which underpin the work should be made available as Hakaly does, but it's the overview and conclusions which are of most interest. However, I'd like to pose the question: Should this work have been published under CC-BY-SA?
