Querying ULAN with curl

[Charles Blair]

The following query works fine in the online SPARQL interface. (I notice it also works without declaring the prefix.)

prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>

select ?s ?p ?o

where { <http://vocab.getty.edu/ulan/500033408> rdfs:label ?o }

However, I've done a lot of searching and yet can't seem to make it work on the command line via curl. Could someone show the correct way to do this? Thanks.

Hi,

I took the URL which the SPARQL end-point generated for the XML response, and just added it (in quotes) after curl on the command line.  It worked OK:

Ah, thank you. That "sparql.xml" does make for a more easy to parse format (as would "sparql.json", I see). Thanks again!

Left to my own devices, I would always use CONSTRUCT instead of SELECT, and request an RDF/XML response. That way I get a machine-processible graph fragment. (I realise there are other points of view on this issue ...)
