<p>Hi James,</p>
<p>Subjects (and to a lesser extent divisions) have always been an
integral part of EPrints. Generally removing them from workflows,
citations and config files like cfg/cfg.d/eprints_render.pl,
cfg/cfg.d/eprint_search_advanced.pl, cfg/cfg.d/views.pl, etc. is
sufficient to hide them without breaking EPrints. If you start
removing them from cfg/cfg.d/eprint_fields.pl is when you are
likely to hit problems like those you mention, as certain aspects
of EPrints expect the subjects or divisions fields to at least be
defined even if they are not used.</p>
<p>I think in this particular (/cgi/oai2) situation, you probably
needed to make sure you disabled the subjects OAI set in
cfg/cfg.d/oai.pl. Unfortunately, there is a rather complex list
of config changes you need to be sure to make if you want to
undefine (i.e. comment out / remove) the subjects field in
eprint_fields.pl and make sure this does not break anything else.
If I get the opportunity, I will see if there is a suitable place
on the wiki to document what this rather complex list of config
changes is.</p>
<p>Regards</p>
<p>David Newman<br>

<div>Update on this after some mooching around. Our "ListSets"
option in OAI2 no longer works and sends me to an error

<div>When I redid the Divisions/Uni Structure recently in
EPrints the Subjects were removed as we haven't used them in
years. This caused a couple of issues with the advanced
search and some abstract pages. Looking at the ListSets page
for another repository, the Subjects are part of this.</div>
<div><br>
</div>
<div>I'm going to attempt to correct it by either altering the
ListSets (probably not) or by resurrecting the Subjects.
I'll update with any success/failure.</div>
<div><br>
</div>
<div>Hopefully I can prevent other would-be unintentional
wreckers following in my footsteps.</div>

This whole area is slightly off my radar so I was hoping
if there are any common things I could check? Obviously
the repository is up and running. I've asked for the
dates of the most recent successful harvest and the
first failure as well as if it is still happening. I
also need to speak with our Computing Services
Department to check if the IPs can get through the
firewall.</div>
<div><br>
</div>
<div>Is there anything else I can/should check based on
all of your collective experience?</div>
<div><br>
</div>
<div>We did recently get a new security certificate, but I
can't imagine that is a problem as we do this each year
without any issues.</div>
<div><br>
</div>
<div>Thanks,</div>
