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:

http://markmail.org/message/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?
