Green and gold are artificial distinctions in open access publishing, mainly driven by the technical and business separation between publishing platforms and institutional and thematic repositories operated by research institutions or research communities. This project builds on the vision of next-generation repositories by pursuing the prospects for greater integration between repositories and journal publishing platforms. It involves developing, through consultation with the academic communities, a conceptual model for highly configurable publishing overlay services to sit atop distributed repository platforms. The model removes the green and gold dichotomy by providing a system that enables academic communities to integrate publishing capabilities with repository capabilities, thereby combining the strength of the two worlds, while building out a community controlled, integrative, and interoperable infrastructure for scholarly communication.
