VODAN-Development/fairdataspace

Code of the fairdataspace as employed for the Humanitarian Data Space and the upcoming Health Data Space Africa # Fair Data Space A Flask-based web application for discovering datasets across FAIR Data Points (FDPs), composing standardized data access request emails, and executing authenticated SPARQL queries. One codebase serves multiple data spaces — each deployment picks its identity (branding, colors, default FDPs, page content) via the `DATASPACE` environment variable. See Multi-dataspace architecture below. ## Overview Data visiting (code-to-data) is an approach where queries are sent to datasets for local execution, returning only verified results. This tool handles the **requester** side of that workflow: 1. **Discover** datasets across multiple FAIR Data Points 2. **Browse and filter** datasets by theme, keyword, or free-text search 3. **Compose** standardized data access request emails grouped by contact 4. **Query** SPARQL endpoints discovered from dataset distributions ## Features ### Dataset Discovery - Add and manage FAIR Data Point endpoints (single or index FDPs) - Browse datasets with filtering by theme, keyword, and free-text search - Pagination and sorting for large dataset collections - Automatic discovery of SPARQL endpoints from DCAT distributions ### Data Access Requests - Add datasets to a request basket - Compose data access requests with structured metadata (name, affiliation, ORCID, purpose) - Automatically group and generate separate emails per dataset contact - Preview and copy composed request emails ### Authenticated SPARQL Queries - Log in with credentials for SPARQL endpoint authentication - Execute read-only SPARQL queries against discovered endpoints - Client-side query federation across multiple endpoints - View aggregated results with per-endpoint breakdown ### Admin - Admin login at `/admin/login` for editing the home and about page content - Dashboard configuration for scheduled aggregate queries ## Multi-dataspace architecture Each deployment serves one data space. A data space is a directory under `dataspaces/` that bundles …
