[EP-tech] Re: Citation count plugin

Hi George,

I think I might be that maintainer, although "maintainer" seems a bit too active a word. I'm not in at work today, so I won't be able to look into your warnings and error until after the weekend. In the meantime, though, I should probably point you towards the GitHub repository of the citation-import plugin: https://github.com/QUTlib/citation-import

Things have changed a great deal since the plugin was uploaded to file.eprints.org (not least being the release of EPrints 3.3 and all its concomitant framework changes); I may have to look into engineering an updated release.

Subject: [EP-tech] Re: Citation count plugin


I found the problem, the configuration files of the plugin don't enable
it anywhere, so I had to add the relevant code manually. More
specifically, I added:

$c->{plugins}{"Import::CitationService::Scopus"}{params}{disable} = 0;
$c->{plugins}{"Import::CitationService::WoS"}{params}{disable} = 0;
$c->{plugins}{"Import::CitationService::GScholar"}{params}{disable} = 0;

in file archives/myrepo/cfg/cfg.d/datasets_citation-count.pl, after the
first "use" statement.

The problem now is that after enabling the plugins, I get a new error:

$ ~/lib/epm/citation-count/bin/import_citationdata --verbose myrepo scopus
"my" variable $mesg masks earlier declaration in same scope at (eval
156) line 114, <DATA> line 751.
Possible attempt to put comments in qw() list at (eval 162) line 18,
<DATA> line 751.
defined(@array) is deprecated at
line 46.
     (Maybe you should just omit the defined()?)

I'll try to ask the plugin's maintainer about what to do with this
error, but any advise is more than welcome!
