Idiomatic way to join on “secondary” keys

If we have a stream that looks like this
Person {
…
OrganizationID
}
that we want to join with another stream
Organization {
ID
…
}
to create a composite record like so:
Person {
…
Organization {
ID
…
}
}
What is the most idiomatic and efficient way to do so in the Apache Beam programming model?
NB: have seen side inputs recommended as a solution to similar problems like this, but it is not applicable here since the effect we are after is that every change to either Person or Organization should yield a new augmented Person-record.
