[EP-tech] Re: Possible importing BibTeX bug in monograph

Hi all,
I was wrong! I thought the import was fine in my previous snapshot, but it wasn't. I installed EPrints 3.3.14 on a clean debian (Jessie), and imported the aforementioned BibTeX file, and I had the same problem again:
$ ./bin/import --verbose --user admin testpamak1 archive BibTeX /tmp/bibtex.bib

You can see near the end of the warning messages that eprint_fieldopt_monograph_type_technicalreport (en) is an undefined phrase, and if I see the eprint's details, "Monograph Type" is not filled with a value (it should be "Technical Report").
Thomas (Lauke), I didn't read your initial email thoroughly (it was tooo early in the morning when I read it:)), and as I now re-read it you said that the phrase warning was raised to you too. This means that the "Monograph Type" field was not imported to you either, so if you check your import, you must see it's empty.
If you confirm this (or anybody else), I'll file a bug report to EPrints src. 

Thanks all again!

Hi everybody!

I checked my BibTeX file on a previous snapshot of my development
machine and it was imported just fine. Thomas Lauke informed me of
achieving the same results in one of his installations as well. I've
also found the file that caused the first warnings (about $mesg being
re-declared), removed it from my configuration, without any effect. So
I'll start by removing one-by-one each config file I've changed in order
to find out which is causing the problem and will try to resolve it.

Thanks all for your help again!

Adam,

As I mentioned in my previous email, I checked the exact code you
suggested and it's fine (hey, don't get me wrong, I know you're having a
hard time answering all our questions in such a limited time:) ).
That's  why I'm curious wrt the reason I'm getting this error. If you
take a closer look into my script's output (the warnings), maybe they
tell you more then they tell me about resolving this issue :).

Moreover, it would be enlightening if someone tried importing the sample
bibtex entry of my previous email in their installation and see if it
imports it correctly (using the command line to see if they get the same
warnings).

Thanks for helping!

Hi everybody,

When importing a @TECHREPORT from a BibTeX file in EPrints 3.3.14 -like
the one I've included for PoC in the end of this email- an eprint is
created that has the value technicalreport in its monograph_type
variable, which is wrong (it should have been "technical_report"). As
you can see from my export, some warnings are returned, some of which
referring to undefined phrases in (el), so I'm not sure if it's
something related to my custom multilingual configuration causing it;
but if so, I have no idea how it is possible, since I'm using EPrints
vanilla import utility.

More specifically, that's what I get:

$ ./bin/import  --verbose --user admin testpamak1 inbox BibTeX
/tmp/my_bibtex.txt

153) line 114, <DATA> line 751.

Can anyone confirm the problem in their repositories as well? If so, I
suppose we should file a bug report in EPrints github.

Ah, and grepping my repostitory for technicalreport returns nothing, so
it's probably created dynamically from BibTeX.pm...? However, looking at
my BibTex.pm's code (lines 340-344), the line adding this code seems
fine (it sets a technical_report). Could this problem be related to the
masking warning I get when running my import command? (and by the way,
how can I find which file causes this message?)

My /tmp/my_bibtex.txt content is:

@TECHREPORT{RePEc:rim:rimwps:15-19,
title = {The Day-of-the-Week Effect is Weak: Evidence from the European
Real Estate Sector},
author = {Bampinas, Georgios and Fountas, Stilianos and Panagiotidis,
Theodore},
year = {2015},
institution = {The Rimini Centre for Economic Analysis},
type = {Working Paper Series},
abstract = {The day-of-the-week effect for the securitized real estate
indices is investigated by employing daily data at the global, European
and country level for the period 1990 to 2010. We test for daily
seasonality in 12 countries using both full sample and
rolling-regression techniques. While the evidence for the former is in
line with the literature, the results for the latter cast severe doubts
concerning the existence of any persistent day-of-the-week effects. Once
we allow our sample to vary over time, the average proportion of
significant coefficients per day ranges between 15% and 24%. We show
that higher average Friday returns evident in previous literature,
remain significant in 21% of the rolling samples. We conclude that daily
seasonality in the European Real Estate sector is subject to the data
mining and sample selection bias criticism.},
