Harvest geospatial metadata when ojsGeo plugin is used #3

For some more background, here are a few links from our demo/test server: This is how the geometadata is shown for an issue of a journal: https://service.tib.eu/optimeta/index.php/optimeta/issue/view/5 For the harvesting, the article landing pages are more interesting:

<meta name="DC.Description" xml:lang="de" content="A boom in volunteered geographic information has led to extensive data-driven exploration and modeling of places. While many studies have used such data to explore human-environment interaction in urban settings, few have investigated natural, non-urban settings. To address this gap, this study systematically explores the content of online reviews of nature-based recreation activities, and develops a fine-grained hierarchical model that includes 28 aspects grouped into three main domains: activity, settings, and emotions/cognition. It further demonstrates how the model can be used to explore the variation in recreation experiences across activities, setting the stage for the analysis of the spatio-temporal variations in recreation experiences in the future. Importantly, the study provides an annotated corpus that can be used as a training dataset for developing methods to automatically capture aspects of recreation experiences in texts."/>

I'm working on an OJS Plugin that collects and exposes geospatial metadata for articles, see https://github.com/TIBHannover/ojsGeo/
I would like to document the idea (e.g., in an issue) of extending
ojsrwith a feature to harvest that metadata as well and ideally provide it as ready to use sf objects so you can show OJS articles on a map with just a few lines of R code. The dependency on sf should be flexible, i.e., the availability if checked only whenhavest_geo = TRUE.Full disclosure: no production instance of OJS is using the plugin yet, but I'll add updates here once interesting data becomes available.
