Geoportal data-entry technology allows the actors who use it, the project management of spatio-temporal documents specified by meta-documents called "Use Case Descriptor" (UCD) which determine the document model, management, life cycle, etc. The system allows you to: (i) access and search for published projects by role for VRE, (ii) access the project publication report, view the publication status (SUCCESS, WARNING, ERROR), etc., (iii ) generate links for visualization on the map, (iv) update the contents of the registered projects through the workflow, (v) manage the relationships (quantity and quality temporal links) between the documents. In general, the technology allows the data entry of any document having spatio-temporal characteristics, whose metadata and payload are specified by one or more "gCube Profile" profiles which determine the structure of the resulting document (JSON).
