[Cod-bugs] Missing Journal Information

[Antanas Vaitkus]

Hello,

just a short note on article IDs in CIFs. Since version 3.2.0 the coreCIF
dictionary [1]
defines the _journal.paper_number data item which is more or less a paper
ID:

    Article number that is used by some journals instead of a page range.
    Usually applies to electronic-only journals.

However, we do not yet properly support it in the COD deposition pipeline.

Sincerely
Antanas
