How to create XSD format for Index Copernicus?


As far as I know <doi/> and <doi></doi> are equivalent with respect to xml specification.


Changing the tag <doi/> to <doi></doi> did the trick for us and we were able to import all the articles in ICI. Thank you very much for building this plugin. It saves us a ton of time.

There was an error in importing the import. Check the xml compatibility with the xsd supplied

Hello, @Surojit_Bera

I have good news. I have experimentally investigated that there is a limitation for affiliation length. It is 250 character. In your problematic article affiliation length is exceeded this value.
The solution is manually cut the affiliation length to 250 characters. This actual for ADESINA JACOBS MOBOLADE (may be other).

The fix will be available with new version of ojs-to-copernicus plug-in.

This is problem with ojs hosting. The tar archiver have to be installed.
There is an anther way. If you have direct access to hosting files you may manually extract archive to OJS_ROOT/plugins/importexport/.
