Currently it does store all citation metadata in the reference, which does not comply with https://www.wikidata.org/wiki/Help:Sources#Scientific,_newspaper_or_magazine_article

• Once a doi/pmid/pmcid is inputed, Citoid should be called first to find alternative IDs of the publication
• If a match is found is should be added with "stated in" (P248)
• If it is not found, create a new item with such metadata and add the new item with "stated in" (P248)

Note: This should not be done for URL!
