Sample SPARQL Queries
Whilst putting together my local cache of useful data sources I wrote a series of SPARQL queries to exercise the data.
They're all pretty trivial, but demonstrate the kinds of data available in each of the data sources as well as illustrating that some of the sources merge together very nicely as care has been taken to reuse standard identifiers, e.g. for countries.
The complete set of queries is browsable, but here's a few:
- List countries and their dialing codes. View results
- List countries and their main currencies (where available in CIA World Fact Book). View Results
- List Countries and their FIPS country code. View Results
- List Countries and their ISO 3166 country code. View Results
- Show natural hazards in the US. View Results
- Which countries observe daily savings?. View Results
With a bit of mapping mashup action, and some user contributed metadata thrown in for good measure, I think there's the basis for a good travel guide application in there somewhere.
