TL:DR; I'm not sure if it just a data problem or i'm tackling the problem wrong
What i'm trying to do is getting a list of entries with variable properties mapped to a well known list of entries with fixed properties
In other words i have a variable textual entry composed of {"ABC (test)" "wrongdata"}
which needs to be mapped to to a fixed entry {"ABC" "test"}
There are a variety of data providers that output entries with different combinations of fields and values that need to possibly be mapped to the same final entry.
