Ubiquity repositories (based on Hyku) are cloud hosted and open source, with no lock-in. Suitable for both large and small institutions, they provide high-quality hosting of publications, special collections, theses, Open Educational Resources and research data all in one place. The repositories are designed to be reputation-enhancing with attention to design, metrics and researcher engagement.

The platform is particularly well suited to multi-tenant solutions (for example see the UK Shared Research Repository) and as an open alternative to Bepress (for example see Pacific University's Common Knowledge repository, which is a successful migration). The platform also benefits from ongoing development of new features in the Advancing Hyku project.

Ubiquity repositories are also fully integrated with our open access publishing platform, providing journal, book, OER and research data publishing.

Ubiquity offers full support for migration, manages all cloud hosting, provides robust SLAs, as well as complete training and support. We also provide a dedicated account manager to assist with the ongoing development of your repository to ensure you get the most out of it.
