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

I think I've worked it out!
Does this: https://github.com/eprints/eprints/pull/356/files
solve it (without the previous fix in place)?

The gory details
--------------------
The $epdata hash is populated in the convert_input method.
At the end of this method there is this:
https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Import/BibTeX.pm#L508
 - which calls '_decode_bibtex' on $epdata.

$epdata is a hash ref - so will be caught here: https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Import/BibTeX.pm#L524-L531

On line #528, the 'type' key is treated as a special case (I'm guessing as it's created in the convert_input method - and doesn't come directly from the BibTex file itself).
I propose that the 'monograph_type' is also a special case (it's always created in convert_input method; never copied from the BibTeX), and should not be passed to the '_decode_bibtex' function on line 529 either...

The previous suggestion just defines the monograph type in a way that it will decode to the right value.
Anything that uses $entry->field( "xxx" ) for its value *should* be decoded.

These lines:
https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/Plugin/Import/BibTeX.pm#L452-L456
are worth a mention too - in case someone (in a few years time) maps something directly to 'monograph_type' from $entry->field - and doesn't realise that it will be skipped in the decoding.

Cheers,
John

Hi John,

I tried importing the BibTeX file through the web form, as you 
suggested, and it breaks the same way. Good question though!
