I would suggest that you mention the Linked Data API [1] as one 
potential model for such web services. While it was developed in order 
to provide an alternative, developer-friendly interface to triple stores 
which would often already have a SPARQL end-point, it is also of value 
in its own right as a generic RESTful API design.

 From a user's perspective, it is of no interest what lies behind the API 
interface - whether a triple store or an entirely different database 
technology - so long as asking the same question causes the same answer 
to be returned.  So it could be a mechanism for harmonising access to 
triple stores and other data being presented as Linked Data.

 From the user's PoV, the approach of having to deal with a unique 
interface, and data format, for each Web Service (as per the examples 
you cite) doesn't really scale beyond accessing a handful of such
