GeoPortal Data Entry App

The Geoportal Data Entry App is a comprehensive web application for managing spatio-temporal documents through "Use Case Descriptors" (UCD) that define their model, lifecycle, and management properties. It provides an intuitive interface for creating, editing, and managing research projects within the gCube Geoportal system.

Overview

This application serves as the primary entry point for researchers and data managers to create and manage complex geospatial projects. It supports the complete data entry workflow from initial project creation through publication, with built-in validation, file management, and relationship handling capabilities.

The Geoportal data-entry technology enables users to manage spatio-temporal documents through "Use Case Descriptors" (UCD) that define their model, lifecycle, and management properties. The system provides comprehensive functionality to:

• Role-based Project Access: Search and access published projects based on VRE role permissions
• Publication Reports: Monitor project publication status with detailed SUCCESS, WARNING, and ERROR reporting
• Map Visualization: Generate links for geographic visualization of spatial data
• Content Updates: Modify registered project contents through configurable workflows
• Relationship Management: Create and manage temporal and qualitative relationships between documents

The technology supports data entry for any document with spatio-temporal characteristics, where metadata structure and payload are defined by one or more gCube Profile configurations that determine the resulting JSON document structure.

Use Case Descriptor (UCD) Framework

The application leverages Use Case Descriptors to define:

• Metadata Schema: JSON-based schema definition for project structure
• Form Configuration: Field types, validation rules, and UI layout
• Workflow Definition: Lifecycle phases and available actions
• File Management: FileSet definitions and upload constraints
• Access Control: Role-based permissions for operations and data access
• GUI Integration: Custom interface configurations per project type

the UCD framework is implemented by gCube CMS Suite
