Describe the problem you would like to solve
Anyone using the Facebook API gets incomplete results from PKP-published content because of missing metatags.
Describe the solution you’d like
The og:url tag should appear on all article pages, and should probably point to the abstract page for each. This way FB resolves all instances of an article the same way. Alternative, it could point to the same URL as the DOI (if that’s different). There are other og: tags that could accompany the articles.
This should be no more than a couple of hours of work.
Ideally, this plugin would be shipped with OJS/OPS and be turned on by default (most users won’t know why they need this).
Who is asking for this feature?
Me, on behalf of people who are trying to do altmetrics. Even though others haven’t realized it (because they haven’t done any research on this topic),
Information on Facebook metatags
Research that would have benefited from this feature.
