An up-to-date, crowd-sourced list of query service endpoints that underlie the massive LOD Cloud Knowledge Graph.
Here is a Google Spreadsheet that contains a list of SPARQL Query Service endpoints. Please feel free to contribute any endpoints not on the list!
The LOD Cloud is a live demonstration of several capabilities offered by RDF-compliant Graph Database Management Systems (a sub-genre of DBMS), particularly –
- Ad-hoc queries – varying complexity from any combination of human or bots
- Performance, Scalability, and Availability
- Entity Relationship Graph Exploration – before and after query solution production
Existing HTTP, ODBC, JDBC, ADOdotNET, and OLE DB compliant apps and services all have access to this massive Knowledge Graph
Richer knowledge can be derived by combining local data with master data from this Knowledge Graph
