The Madrigal Database manages and serves archival and real-time data from upper-atmosphere science instruments in multiple formats.
Linked COVID-19 Data
Linked COVID-19 Data transforms public datasets into RDF and provides demonstration dashboards through a SPARQL endpoint.
About Linked COVID-19 Data
Linked COVID-19 Data converts COVID-19 case data from the Johns Hopkins University (JHU), European Centre for Disease Prevention and Control (ECDC) and Robert Koch Institute (RKI) into RDF, a linked data format. It also hosts demonstration dashboards that query a SPARQL endpoint, covering maps, case counts, country comparisons, daily cases and doubling time, along with statistics for German federal states.
The dashboards are labeled beta and the SPARQL endpoint is described as a prototype and demo. The official data and Python script are published on Zenodo with DOIs.
Key features
- Transforms JHU, ECDC and RKI COVID-19 data into RDF
- Dashboards built with Highcharts that query a SPARQL endpoint
- COVID-19 maps using JHU and RKI data combined with Wikidata
- Statistics for German federal states from RKI data
- Country comparison, country case, daily case and doubling time views based on JHU data
- Official data and Python script archived on Zenodo with DOIs
Best for: Researchers and developers who want to explore COVID-19 case data in RDF through SPARQL queries.
Good for
- Official data and Python script are archived on Zenodo with DOIs
- Converts data from three separate sources into one RDF format
- Dashboards show the data without requiring users to write SPARQL queries
Watch out for
- Dashboards are labeled beta
- The SPARQL endpoint is described as a prototype and demo
- Statistics for German federal states cover German states only
