My university does something similar with its Digital Library and its related projects. The main repository hosts around 140,000 objects which can be accessed alongside metadata and in multiple formats here: http://digital.library.unt.edu/ http://digital.library.unt.edu/ The Django app and libraries running the site are built and maintained in-house, and are open source: https://github.com/unt-libraries https://github.com/unt-libraries (the Django project/app itself is 'coda')
