Description

I would like LookupRecord to be able to allow multiple lookups per record.

Imagine the following JSON:

[{“key”:”foo”, “innerrecord”:[

{“key”: “value1”}

, {“key”:”value2”}, {“key”:”value3”}}]

There is currently no way to be able to do lookups on the values of "innerrecord"

to be able to give:

[{“key”:”foo”, “innerrecord”:[

{“key”: “value1”,"enhanced":1}

, {“key”:”value2”}, {“key”:”value3”,"enhanced":3}}]

I'm not certain of what the spec for the lookup key would look like, maybe something like

/innermost[i]/key ?

and then the result would go into

/inntermost[i]/enhanced? 

 

Thats just an implementation thought though
