GOCDB is the official repository for storing and presenting EGI and WLCG topology and resource information. It is a definitive information source, intentionally designed to have no dependencies on other operational tools for information. Because GOCDB is a primary data-input source, the portal applies a range of business rules and data-validations to control input. It applies a comprehensive Role-based authorization model that enables different actions over different target resources. The Role model allows communities to manage their own resources where users with existing roles can approve or reject new role-requests.
