questions on the specs

[Nic Volanschi]

Hi Kris,
       
Could you please explain what do you mean in the specs of JSONQuery [1]
by <<The current JSONQuery syntax meets the majority of these goals but
there are still additional constructs that are needed for more
comprehensive querying capabilities.>> ?
       
Is a query mechanism in Json-like syntax interesting in this respect?
For instance, [=~ {age:%a, children:[%c|%_]} ] for extracting the age
and the elder children from each element of an array of objects.
       
Also, when you say <<Missing capabilities include array matching>>, what
kind of matching do you think of? Is it something else than the [?expr]
operator? Is it interesting in this respect to add matching of objects
in some _user-definable_ concrete syntax (more specialized than the
generic JSON syntax)?
       
Nic.
