Unfortunately, nothing like that. In specter terms, the namespace is determined by the path. Here's a real-ish example. Input:
{:name "Joe"
:addresses
[{:street-name "Test St."
:city "Olympia"
:state "NJ"}]
:identifications
[{:type :license
:issuer
{:name "DMV"
:entries
[{:code "DLSDLKDSK"
:algo "akkak"}]}}]}
Output
{:person/name "Joe"
:person/addresses
[{:address/street-name "Test St."
:address/city "Olympia"
:address/state "NJ"}]
:person/identifications
[{:identification/type :license
:identification/issuer
{:issuer/name "DMV"
:issuer/entries
[{:entry/code "DLSDLKDSK"
:entry/algo "akkak"}]}}]}
And this is how I solved it in specter (but it's horrendous — if I keep the specter I'll break this apart a bit):
