Index Copernicus XML Export for OJS 3.4+ (Native Export File Too Large >100MB)

I would like to ask whether there is any working plugin or recommended solution to export XML specifically for Index Copernicus in OJS version 3.4 and above.

I have already followed the discussion and solution shared in this thread:
https://forum.pkp.sfu.ca/t/need-index-copernicus-plugin-for-3-4-0-7/94514

Based on that suggestion, I tried using the native OJS XML export feature. However, I encountered a practical issue:

  • The exported XML file size is over 100 MB

  • Index Copernicus does not allow uploading files of that size

  • As a result, the XML export cannot be submitted successfully

My questions are:

  1. Is there any dedicated Index Copernicus export plugin compatible with OJS 3.4+?

  2. Is there a recommended way to split the XML export (per issue / per year / per volume) while remaining compatible with Index Copernicus requirements?

  3. Has anyone successfully submitted OJS 3.4+ metadata to Index Copernicus, and if so, what workflow did you use?

Any guidance, plugin reference, or best practice would be greatly appreciated.

Thank you in advance for your help.

Native XML strives to preserve everything, including the files participating in the editorial workflow. The files may be big, there may be many of them, and encoding them in base64 doesn’t make them smaller.

Per-issue Native XMLs are smaller, although even they may be large depending on the particular case.

If Index Copernicus doesn’t require the files, only the metadata, your best bet with Native XML may be to remove <embed encoding="base64">…</embed> to reduce the file size. Most probably, you will also have to remove one or several parent elements to keep the XML files compliant with the schema.
