Dublin Core is the main metadata schema for many institutional repositories, for example the DSpace platform https://github.com/DSpace/dspace https://github.com/DSpace/dspace. The schema essentially only covers basic bibliographic metadata and has a strong pre-digital library feel to it. We end up augmenting with other custom schemas to be able to describe content in our repository, for example podcasts and journal articles with different issue and online dates, as well as extra metadata like author affiliations, funders, internal programs etc.
