cURL syntax to query the TDWG sandbox SPARQL endpoint

gistfile1.txt

curl --data-urlencode "[email protected]" http://tdwg-rdf.phylodiversity.net/store2/sparql

Notes:

1. This assumes that cURL is installed and in the PATH for your computer.
2. The command is given from the DOS command line from the directory that contains the file test.sparql .
3. The file test.sparql contains a valid SPARQL query.
4. --data passes the data contained in the file as a the query string so that you don't have to try to encode it in the URL.
5. -urlencode allows you to have spaces in the SPARQL query and not have to escape them with "+". It escapes other "bad" characters.
6. The results are displayed directly in the DOS window. They can be piped into a file using ">", e.g.
   curl --data-urlencode "[email protected]" http://tdwg-rdf.phylodiversity.net/store2/sparql > results.xml

The triples are loaded into the "store3" endpoint, which returns JSON. So the same command can be given replacing "store2" with "store3" and the result will be in JSON. This endpoint seems a lot slower and more prone to breaking with complex queries.
