Hello bg,
For describing the subsets you want, why not use as a bottom representation
something more connected with clojure datastructures?

Like
set literal => set of sibling keys
Vector => path to an inner key
Map => I see no usage for maps right now

Your example could then become:

#{[:name]
     [:email]
     [:adress #{:city :state}]
     [:spouse #{:name [:address #{:city :state}]}

What about that ?

Hi,

I have a problem wherein I need to select subsets of a given map;
think about select-keys, but with arbitrary nesting.

For example, consider this map -

(def my-map {:name "John Doe"
              :email "j...@doe.com"
              :address {:house "42"
                        :street "Moon St."
                        :city "San Francisco"
                        :state "CA"
                        :zip 76509
                        :mobile "+188888888"}
              :ssn "123456"
              :spouse {:name "Jane Doe"
                       :ssn "654321"
                       :relation :wife
                       :address {:house "42"
                                 :street "Moon St."
                                 :city "Atlanta"
                                 :state "GA"
                                 :zip 76509
                                 :mobile "+188888888"}}})

>From the above map, I want to extract this sub-map -

{:spouse {:name "Jane Doe", :address {:state "GA", :city "Atlanta"}},
:name "John Doe",
:email "j...@doe.com",
:address {:state "CA", :city "San Francisco"}}

What would be a good way to express this sub-map so that I can pass it
on to a function?

I am thinking about something like this -

[:name :email {:address [:city :state]} {:spouse [:name {:address
[:city :state]}]}]

Example implementations are also welcome.

Regards,
BG
