MacSphere Institutional Repository is one of 8 APIs that [McMaster University](https://apis.io/providers/mcmaster/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Library, OAI-PMH, DSpace, Open Access, and Institutional Repository. The published artifact set on APIs.io includes API documentation.

McMaster University Libraries' institutional repository of theses, dissertations and open-access research outputs. DSpace 8.2, self-hosted, holding 26,361 items with an earliest datestamp of 2014-06-17. Exposes a conformant OAI-PMH 2.0 interface offering twelve metadata formats (oai_dc, qdc, dim, mods, mets, didl, ore, xoai, rdf, marc, rioxx, uketd_dc) and the DSpace REST API for anonymous read. NO CONTRACT IS SAVED FOR THIS SURFACE, deliberately. McMaster runs the deployment, but the REST API is DSpace's generic contract shipped by every DSpace institution; saving it here would credit McMaster with DSpace's engineering. The deployment is the institutional fact and that is what is recorded.
