Hi @asmecher,
When you have the time, would you mind checking GitHub - ajnyga/embedGalley: OJS3 plugin for visualizing JATS XML galleys again?
It should have all the things fixed you commented on. I will still add a check for multilingual XML files and check that it is the Article Text component that is used. I will also see if I could include this: Improve Google Scholar exposure with reference metatags!
What I have been thinking about is how does the embedGalley approach work with the OJS statistics framework? Basically “real” article views are counted based on the galley downloads/views. How would the embedGalley fit with the COUNTER rules? Maybe @ctgraham and/or @bozana could comment on this as well?
