The World Bank is the largest single source of development knowledge. The World Bank Open Knowledge Repository (OKR) is The World Bank’s official open access repository for its research outputs and knowledge products. Through the OKR, the World Bank collects, disseminates, and permanently preserves its intellectual output in digital form. The OKR also increases the range of people who can discover and access Bank content - from governments and civil society organizations (CSOs), to students and the general public. The OKR is built on DSpace and is interoperable with other repositories. It supports optimal discoverability and reusability of the content by complying with Dublin Core Metadata Initiative (DCMI) standards. All OKR metadata is exposed through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) protocol. By extending and improving access to World Bank research, the World Bank aims to encourage innovation and allow anyone in the world to use Bank knowledge to help improve the lives of those living in poverty.
