Orpheus is a database of academic journals’ attributes that are frequently required by repository managers, such as revenue model (subscription, hybrid or fully Open Access), self-archiving policies, licences, contacts for queries and article processing charges (APCs). It features web frontends for users and administrators, and a RESTful API for integration with repository platforms and other services. Orpheus also comes with a collection of Python parsers for datasets commonly used by repository staff, such as lists of embargoes and APCs from major publishers (Elsevier, Wiley, Taylor & Francis, Oxford University Press and Cambridge University Press) and the databases DOAJ and SHERPA/RoMEO. Orpheus was recently integrated with the Cambridge DSpace repository (Apollo) and auxiliary systems, which has enabled embargo periods to be automatically applied to deposited articles and streamlined the process of advising researchers on payments, licences and compliance to funders' Open Access policies. Orpheus’ source code, available at https://github.com/osc-cam/orpheus, may be easily expanded or tailored to meet the particular needs of other repositories and Scholarly Communication services.
