[libdb-develop] FRBR paper uses wrong word?

[Terry H. <ha...@an...>]

I also wanted to mention an oddity about the FRBR paper that 
you refered me to. There is a bizarre blunder in this paper 
in the (mis-)usage of the word "Equinox".  Apparently the 
author has confused it with the word "Epoch", i.e.:

"Equinox" has three meanings: 1) one of the two days of the 
year when the night is (nearly) the same length as the day, 
2) an instant in time when the Earth's rotational pole is 
exactly perpendicular to the vector from the Earth's core 
to the Sun's core (which occurs on those days), 3) one of 
the two points in space where the ecliptic crosses the 
equator.

"Epoch" is an absolute instant in time used as a reference 
point.  Usually distinguished from "Interval", being the 
time between two instants, or between an instant and the 
epoch.

I believe that "Epoch" should be substituted for the word 
"Equinox" throughout this paper.  And I'm a little 
mystified that this did not get caught in peer-review of 
the paper.  How much review has this paper seen?

I do hope that the world does not accept FRBR as a standard 
with this mistake uncorrected! :-O

Cheers,
Terry
