Thanks for that. Very interesting.

The discussion about reuse is at: https://youtu.be/2-U-Qd37WgE?t=31m26s, 
and I agree that if you want developers to include your information 
(which is the idea of linked data), it is necessary to reuse code 
whenever possible. Otherwise, you are creating a huge additional hurdle 
for the developers and many will choose not to include your information 
in any tools they create.

Of course, the problem with using other codes is that you end up stuck 
in certain ways if they define things differently than you do. So, that 
is why in my previous message I gave the definitions of "event" as used 
in other implementations. None of them use anything that is similar to 
any library usage. Therefore, if we are to make something that will be 
useful and valid in an "events" semantic system created by somebody 
else, we have to decide how to index our information to match others' 
ideas of events.

If an event is seen only as a meeting of people, then in addition to the 
111s, there will also be many, but far from all, 110s (e.g. 110     2_ 
|a Air Traffic Control Association. |b Annual Meeting |n (22nd : |d 1977 
: |c Las Vegas, Nev.)) and even many 151/110 jurisdictional names (e.g. 
110     10 |a United States. |b Congress |n (101st : |d 1989-1990))

If an event is supposed to cover other "things that happen" caused by 
humans such as wars and battles or events caused by non-humans, the new 
index will need to include some, but not all, 150s (150 __ |a Hurricane 
Katrina, 2005) and 151s (151     __ |a United States |x History |y Civil 
War, 1861-1865).

With subjects, there is the additional complexity that there are 
subdivisions, e.g. the subject "United States--History--Civil War, 
1861-1865--Bibliography". Would this still be considered an event?

If not, there is the URI for this subject, which includes the entire 
string. http://id.loc.gov/authorities/subjects/sh2007100437.html. Would 
this entire URI still be considered an event? If not, how would it work 
vis-a-vis the URI for "United States--History--Civil War, 1861-1865"?

Many others view events as individual performances as for instance, when 
someone wants to buy or sell tickets to a musical concert. Libraries 
don't code to this level and you need to look at the entire record for 
individual performance information.

No matter what, it sounds like adding "event" would mean a major change 
for our current data.
