Subject: Re: [cti] Sanity checking on references to other objects
Hi All,
I’m consolidating the discussion on “linking to other objects” to this thread.
References from various threads:

cbbw5zilfgzodcpf - suggest the use of an object hash.
I suggest use of the modified_time of the referenced object.
The modified_time is a single comparison which also provides temporal positioning which end recipients can leverage for decision marking either manual or automated.
Example:
· Entity_B creates Object_B at with create/modify_time = 0
· Entity_A creates an Object_A with reference to Object_B and create/modify_time = 1
· Entity_B updates Object_B at with modify_time = 2
· Entity_C gets Object_A and all Object_Bs and has the ability to determine which instance of Object_B Entity_A is referencing.
This is less trivial in a fast sharing environment where multiple versions of an object are shared independently.
Thoughts?
