Hello,
I have recently come accross the following issue when discussing with Google Scholar team member. For back issues we use other publication dates for online version compared to the actual publication date of the original print version – this is due to the fact that the online version has been published on a basis of new terms (open access, CC licences). So, e.g., the issue published in print in 1960 has been published online in 2014, and 2014 is put as the year in publication date field of this issue and all articles. All other fields such as vol, iss, year are filled based on the original issue (e.g. vol 60, iss 2, year 1960). However, this couses that Google Scholar displays, following the above example, year 2014 as the publication date of the article from 1960. I noticed that the source code of an article's landing page has the following metadata:
meta name="citation_date" content="xxx"
meta name="citation_volume" content="xxx"
meta name="citation_issue" content="xxx"The "citation_date" part takes data from the article's "publication date". Maybe it would be reasonable to distinguish these dates in metadata? Following Wiley, they have, e.g.:
meta xmlns="http://www.w3.org/1999/xhtml" name="citation_online_date" content="2005/02/03"
meta xmlns="http://www.w3.org/1999/xhtml" name="citation_publication_date" content="1968/11/01"So for OJS "citation_online_date" could come from article's "publication date" field while "citation_publication_date" from the issue's year? Would it be enough? Or there would be additional field for inserting original publication date.
Best,
Peter
