Today I fellow passes me this url and asked about permalinks (in general, as well as based on this service): http://www.permalinks.cc/
My answer? In OJS a service like this won't be useful as far as every article owns a unique
url... to reach the PDF, HTML o whatever version of the article you need... although it article changes in future.
But in confidence, I didn't feel sure about this answer and I don't know if I'm missing any benefit of playing with a service like the one I posted.
The only scenario I can imagine this service could be useful it's in a case you migrate from OJS to a different e-Magazine system... but it's a partial benefit, as far as you are moving your dependency from your OJS' url to an external (uncontrolled) service.
Am I missing something? Could OJS take advantage of a service like permalinks.cc?
I just hope I explained myself.
Thanks for your help,
