Hmm, we're failing to communicate here. Sure, you _could_ conceptualize 
things that way. It's just that it wouldn't solve the problem that you 
were proposing it to solve.

The original problem identified was a user who wanted: "Show me all the 
things originally written in year X-Y, (regardless of when the 
particular reprint was published, I want the stuff originally written 
conceived in that range.)" Right?

So, sure you could conceive of something written in Plato's time to be 
"about" that time. But the problem posed was not a user wanting 
everything "about" that time. It was a user wanting things originally 
written in that time.

If you record Historical works about Plato's time but which were written 
in the 20th century a "Plato's time" 045, and you ALSO record things 
originally written in Plato's time a "Plato's time" 045....

...then we can now solve a different user problem that nobody had 
suggested was a problem in a first place, the problem "Show me 
everything about Plato's time (and I consider things written in that 
time to be about it to)".

But we still can't solve the problem that was posed, that you were 
proposing could be solved, but which can't be. The system still can't 
assemble a set of things originally written/conceived in Plato's time.  
Therefore the data is just as useless as it was before for solving that 
problem.

Do you understand this?

This exchange is probably an example of the difficulty of catalogers and 
programmers to communicate, I guess. It is probably frustrating for us 
both, we seem to be talking about different things while trying to talk 
about the same thing.

Sure, you can add more data in a way that is a nice internally 
consistent "can be considered" thing that might make sense to you. But 
if doesn't allow the system to answer the question you thought you were 
providing for, the question that you know or believe that users want 
answered, it's useless. The point isn't just putting the data in the 
record somewhere that can be justified 'can be considered' logically 
coherent;  it has to be putting the data in the record in a way that the 
system can answer the questions you want the system to be able to 
answer. If metadata designers can't think in those terms, the metadata 
will not be functional.
