Hi Dan.
Yes, 'copy_id' is what I was looking for. Thank you so much for that!
We need to have the id from the asset.copy table in the 852 subfield f
of our Z39.50 output for our holdings. I'm not sure exactly why but it
is my understanding that certain vendors that we work with need it there.
If there is some other place we should be doing this I would like to
know. It seems to me WWW/SuperCat.pm is the only place to do it.
Thanks again!

Hello John,
This part of the code is pulling data from the unapi.bre() function in
the DB, so in this case, you want 'copy_id', i.e.:
...
f => $copy->getAttribute('copy_id'),
...
This said, I think we'd all be interested to know exactly what you are
trying to accomplish, as there are other existing APIs for getting copy
IDs, so I am not sure if adding it into this SRU function is the easiest
way to go.
Sincerely,
Dan

Hello. I am working in the perl module WWW/SuperCat.pm and trying
to get the id of a row in asset.copy. For some reason I am getting
back what looks like an unAPI URI instead of just the id of the
row. I've been staring at this for a while and not sure why this is
happening or the best way to fix it. This is around line 2030 in my
WWW/SuperCat.pm in EG 2.12.8. The basic code flow in
WWW/SuperCat.pm is:
results retrieved from cstore
my $marcxml = XML::LibXML->load_xml(...);
my @copies;
for my $node ($marcxml->getElementsByTagName('holdings')) {
for my $volume ($node->getElementsByTagName('volume')) {
for my $copy ($volume->getElementsByTagName('copy')) {
push @copies, {
f => $copy->getAttribute('id'),
};
f ends up with unAPI stuff in it instead of just the row id that I
am looking for. It looks like:
ftag:open-ils.org:U2@acp/5826234
The part that I want is after the / I put in a hack to manipulate
the unAPI string and strip out the / and everything in front of it
but I don't want to leave it that way. I would like to do this the
correct way.
I'm not sure if it really is supposed to behave this way or not.
Assuming it is, I was thinking maybe a function exists that can
extract the row id from the unAPI URI? I wasn’t able to find one.
Any ideas how to correctly get just the real row id from the
database without the unAPI stuff?
Thanks in advance!
