Subject or disciplinary repositories and general purpose repositories have a long history. These repositories are tailor-made by experts in a field and are targeted for a specialized group of users so features can be developed accordingly.
Some repositories are general purpose or format-based like Dataverse (Harvard), an open source research data repository. They are generally open to authors with any or no institutional affiliation.
