This is great Luis -- in fact I'd already taken a look (and posted a 
comment) and I should have mentioned that in my original post.

I hadn't seen this. My question here, as with your blog post, is whether 
this is intended to the 'definition' or a general discussion/preamble. I 
think it would make sense to keep these pretty separate within the page 
-- the preamble can be fairly verbose but I think one would want to keep 
the definition pretty simple.

I'm not sure what one means by 'licensing of the APIs' here. If the 
underlying code which creates those APIs (the code running the service) 
is open then one would expect to the APIs to be -- unless one is arguing 
that the APIs could somehow be patented while the code kept 'open' (and 
this problem then isn't specific to services but to software patents and 
open source generally ...)

I also think we should steer well clear of reliability questions. OSI 
does not mandate you as a software provider have to stay around to 
maintain and develop your software only that what you currently provide 
is open. Similarly an Open Services Definition (OSD) is there to ensure 
I can easily move to another service -- and if necessary duplicate the 
existing one so that if you fall over tomorrow someone else can take 
over. Thus reliability is ensured by competition not by the Definition

Good point. That should be fixed.

did something get cut off here?
