Dataset Dashboard

The dataset dashboard is a tool for getting a quick overview over a SPARQL endpoint, or a graph inside a SPARQL endpoint.

Its current widgets include:

• summary descriptor
• basic class/property statistics
• spatial descriptor
• temporal descriptor

To use the application you can either:

• go to http://onto.fel.cvut.cz/dataset-dashboard, in case you want to overview a predefined dataset
• make a request of the form https://onto.fel.cvut.cz/dataset-dashboard/#/dashboard/online?endpointUrl=<ENDPOINT_URL>&graphIri=<GRAPH_IRI>, where <ENDPOINT_URL> is the url-encoded URL of a SPARQL endpoint and <GRAPH_IRI> is an identifier of a graph inside the endpoint, for example https://onto.fel.cvut.cz/dataset-dashboard/#/dashboard/online?endpointUrl=https://linked.opendata.cz/sparql&graphIri=http://data.czso.cz/resource/dataset/average-salaries

The system is built on our stack:

• JOPA
• SPipes
• Dataset Descriptor Ontology
