Each of its articles is free online, and it doesn't seem to use the Springer Open Choice hybrid model. I'd call it Springer's first full OA journal except that it requires individual request and permission for all "reuse" (no qualifications). By contrast, Springer's hybrid OA articles use CC licenses.
Clearly something is wrong: the same "reuse" page incorrectly says that access requires payment ("To purchase or view a PDF of this article, please...select 'add to shopping cart' "), and of course copyright law permits some reuse without permission.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
