DESCRIPTION
Mahara “Isolated Institutions” feature allows controlling user interaction across the institution boundaries by implementing “Walled garden” effect and maintaining trust relationship between institutions. This is useful feature for large scale use when the same instance of Mahara is shared by several schools and has long been on the roadmap. A year ago LUNS has developed this feature for the private client who permitted to integrate it into the core, currently the feature is awaiting to be updated with 1.4 and revised by core developers. The designed implementation of institution isolation and privilege control mechanism allows to have both isolated and normal institutions co-exist on the same Mahara instance without interference and even setting trust relationships between them.The presentation is aimed to the broad audience of Mahara practitioners. It will introduce the designed Institution Isolation concept and include live demonstration of the feature.
