Content management is not Moodles strongest point, which is causing a massive issue with scaling and replicating content. We have tried using the H5P content bank (Moodle v3.10) but even this is very limited. Providing an iframe to a specific piece of content might be a possible solution so that there is a single source of truth will multiple windows onto this content, then when the source is updated, so all views are updated.
I have tried a couple of things in Moodle, like creating a hidden course with activities such as a Page or a Book to act as this "source", but really for this to work we need a link to the specific HTML content (the actual page or chapter in a book), NOT to the Moodle URL as this then embeds the entire Moodle site.
Is it possible to get a URL to a specific piece of content in Moodle?
