Scopus/Crossref Plugin for OJS 3.x : This plugin shows the total number of citations and a "cited by" article list from Scopus and/or Crossref.

Hi there 👋

citations's Issues

not working (OJS 3.1.2.4)

Describe the bug
The plugin is not working in our OJS 3.1.2.4 (see image below). Initially we thought this was due to the keys not being saved. But I checked #3 and indeed the Crossref boxes are blue (we have put in the keys for this) and the Scopus keys are not (keys not used), so this seems to work as described.

However we get no response from the plugin.
We tried selecting only crossref, only scopus, no scholar, no PMC ... nothing changes in the front end.

What application are you using?
OJS 3.1.2.4
Linux server, PHP 7.3.25

Additional information
Screenshot from front-end:

PKP Forum Post: Block not shown in OJS 3.3.0-6

Describe the bug
https://forum.pkp.sfu.ca/t/question-about-crossref-cited-by-plugin/67797/2

The query result for the number of citations of the article is 0

I added the Scopus/Crossref Citations Plugin in the OJS Plug-in Center and filled in the corresponding values ​​in the prompted fields. However, when I configured my journal, it did not seem to take effect. My judgment is based on my An article in the journal is included in Europe PMC and can be searched through the article title. However, by clicking the Europe PMC icon of the plug-in, in the newly opened web page, the search field is (REF:10.54844/prm.2022.0098), I want to This is the DOI of this article, but no search results were found. The prompt returned: There are no citations matching your query. I want to know what went wrong. Can you tell me, thank you very much.

Modifying the instructions for Crossref credentials

Hi @RBoelter. My name is Isaac Farley, Crossref technical support manager. Thanks for creating the Scopus/Crossref Plugin for OJS 3.x! Many of our members using OJS 3 make use of this plugin, so we're all grateful for it being available.

I wanted to suggest some improvements to the Crossref section of the instructions.

1. We recently made changes to the Cited-by service. It is now open to all of our members and enabled from the start of their membership, so there's no need for our members to contact us to request that we enable it. We also no longer require that our members register their own references before using the Cited-by service (albeit we do strongly encourage that members register all their references). That last bit wasn't included in your instructions, but just adding it here to be thorough and as an FYI to anyone reading this request.

So, for this first improvement, would you be open to updating the messaging from 'You must contact Crossref to ask for the Cited-by service to be enabled for your prefix(es)' to instead read 'The Cited-by service is enabled by default for all Crossref members/prefixes'?

2. Cited-by is not powered by our API. And, use of our API does not require credentials. Thus, the instructions about using a 'Crossref API' username and password to enable the plugin does cause some confusion for our members. Instead, we refer to those credentials simply as members' 'Crossref username' and 'Crossref password.'

So, for this second improvement, would you be open to updating the instructions to remove the mention of our API? This is more accurate:

In order to use the Cited-by service, you must be a Crossref member. Membership with Crossref may require fees. Please enter your Crossref credentials below.

Enter here your Crossref username
Enter here your Crossref password

Thanks in advance for considering these changes,
Isaac

crossref cited-by not showing citation numbers

Hi there,
I've seen some questions about missing citation numbers for scopus with this plugin. For me scopus is working fine but crossref is not.
e.g. https://www.genresj.org/index.php/grj/article/view/genresj.2020.1.4-16

I contacted Crossref, they said I dont have to apply for cited-by anymore and i can just use my normal crossref user login for the plugin. Any idea what's wrong?

Thanks for your help
Sandra

Can't install via plugin gallery

Hi,

My website doesn't allow me to install this plugin via plugin gallery since it can't unpack tar.gz file.
Because of that I tried to install it manually by uploading to website, but unfortunately it's not working.
Is there a better way to install it manually, maybe manually creating the required data tables, dependencies..

[OJS 3.3.0.13] Scopus/Crossref plugin does not show Scopus citations

Hi,

I have the Scopus/Crossref plugin installed within our OJS platform, but I’m having a problem with it not displaying Scopus citations. Crossref citations are displayed normally, but Scopus citations are not. What can I do in this case or how can I solve this problem.
