I'm having trouble understanding what you mean by "de-identified but
event linkable." Assuming an event is some specific transaction, does
this mean that it's possible to link together separate data records
about the same transaction? Or does it mean that it's possible to link
together separate data records about different transactions?

An example of the former: when data is moved to yellow, a novel, random
uuid is generated and used as the key.

An example of the latter: when data is moved to yellow, a one-way hash
of PII is used as the key. Later, when another transaction with the same
user occurs, the same hash is generated for that transaction's data.


Thanks in advance,
Ted
