Apologies for the delayed reply -- I somehow missed this when it came in 
last week. Comments interleaved below.

I was using API here in the context of the discussion in the previous 
email. That is it really is just shorthand for saying that that data 
format should be open (i.e. either give it out in a standard and 
well-known open format or provide code (an 'api') which provides for 
easy access and processing of the said data). Frankly reading over this 
it is just confusing and this requirement should be changed to:

   * Its data is open as defined by the open knowledge definition though 
with the exception that where the data is personal in nature the data 
need only be made available to the user (i.e. the owner of that account).

Remark: The OKD requires technological openness (i.e. provision in an 
open format)

I entirely agree. As I said in my previous comment I wasn't advocating 
open APIs in the traditional sense (we've already discussed their 
deficiencies).

Again I agree the source code should be F/OSS and must be made available 
  (this ties into the open knowledge definition's social access 
requirement: not only should be allowed to get the information but you 
should actually be able to do so).

Good point though I'm not sure that calls to non-open web services would 
be a problem. Sure it would render the service pretty useless without 
access to them but one allows F/OSS software to use non F/OSS libraries 
(e.g. Windows APIs ...)

Yes I think one can reuse the OKD in defining what one means by open data.
