Publication date metadata for some articles is wrong, messing up Google Scholar

[Dan Scott]

It looks like there is a problem with the publication date metadata for at least some articles.

For example, https://journal.code4lib.org/articles/2510 was part of Issue 9, published on 2010-03-22. But the metadata says:

<meta name="citation_publication_date" content="2019/02/14">

Issue 43 was published on 2019-02-14, so maybe something went awry then?

The human-readable text, however, still gets it right:

<p id="issueDesignation"><a href="https://journal.code4lib.org/issues/issues/issue9">Issue 9, 2010-03-22</a></p>

Another article from issue 9 has the same problem: https://journal.code4lib.org/articles/2493 - but randomly checking a few articles from other issues before and after Issue 9 hasn't turned any other cases up. Still, if there's a reasonably easy way to systematically check this, it would be great. ( I guess we could crawl all articles and compare their metadata to the issue in which they were published but hopefully this is easier at the database level...)

You can see that Google Scholar has been confused by this, as it lists 2019 as the year of publication for the primary version of the article:

https://scholar.google.ca/scholar?q=Using+Cloud+Services+for+Library+IT+Infrastructure

(If you click "All 4 versions" you can see that it has other versions, such as the EBSCOHost copy, that still have a 2010 publication date, but the erroneous data affects filter by year functionality, etc)

I imagine other services crawling the journal might run into the same problem.

Hi Dan,

Thanks for finding that and bringing it to the Editorial Committee's
attention. I've updated the publication dates for the articles in
issue 9. If you see any other issues please let us know.
