Roberto (@abec), o correto seria solicitar correção para a editora em questão (10.5935), pois não temos acesso aos metadados depositados por eles. @DanieleGullo, você já tentou esse contato?
I will post the situation in English to see if someone from Crossref can help us with another idea. This is the email Daniele got from Crossref when she tried to apply for Similarity Check:
We have already received your application for the Similarity Check service, and unfortunately, we are still encountering the same issues as before.
Many of your DOIs all share the same Similarity Check URL; either http://www.arquivosonline.com.br/2016/revista-eletronica.asp or http://www.onlineijcs.org/. These are not the full-text URLs that we require for your content. Other DOIs have what look like valid URLs, but they do not work. For example, 10.5935/abc.20140020 has http://www.arquivosonline.com.br/2014/10202/pdf/10202020.pdf, which is a URL that does not work.
You’ll need to update your Similarity Check URLs so that each resolves to the full-text PDF of the content for each DOI. You can find instructions for the quickest way to add/update the full-text URLs for your existing DOIs on our support site.
This would be easy if Daniele had her own prefix, but she was paying a Brazilian editorial service company to deposit her DOIs and she has no access to the content.
Is there any other way (than waiting for the company) to fix it?
