get json through http request to ulan

[ziny...@gmail.com]

Hi,

I'd like to pass a sparql query through a url and get the data in json. 

Can I get xml/json output through a query like this:

http://vocab.getty.edu/sparql?query=select+*+%7B%3Fx+luc%3Aterm+%22vincent+van+gogh%22%3Bskos%3AinScheme+ulan%3A%3Bgvp%3AprefLabelGVP%2Fxl%3AliteralForm+%3Fname%3Brdf%3Atype+gvp%3APersonConcept%7D&_implicit=false&implicit=true&_equivalent=false&_form=%2Fsparql

My query will be the same, I'm just exchanging the the artists name (vincent+van+gogh)

How does the url need to be structured?

thanks

Zin

Hi Zin,

Two things:

1) You can alter the query point you are hitting from "/sparql" to
"/sparql.json"

http://vocab.getty.edu/sparql.json?query=select+*+%7B%3Fx+luc%3Aterm+%22vincent+van+gogh%22%3Bskos%3AinScheme+ulan%3A%3Bgvp%3AprefLabelGVP%2Fxl%3AliteralForm+%3Fname%3Brdf%3Atype+gvp%3APersonConcept%7D&_implicit=false&implicit=true&_equivalent=false&_form=%2Fsparql

There's probably a way to do it with content negotiation, but this might
meet your needs.


2) As for changing the name, just change it in your query string;

http://vocab.getty.edu/sparql.json?query=select+*+%7B%3Fx+luc%3Aterm+%22Leonardo+da+Vinci%22%3Bskos%3AinScheme+ulan%3A%3Bgvp%3AprefLabelGVP%2Fxl%3AliteralForm+%3Fname%3Brdf%3Atype+gvp%3APersonConcept%7D&_implicit=false&implicit=true&_equivalent=false&_form=%2Fsparql

Here's the same URL but this time it will query Leonardo da Vinci..


HTH,
Kevin

Thanks alot. I already figured out the 2nd part and am extracting the data via scrapy and xpaths. But 1. will help me doing this in a more elegant manner

You might also consider downloading the source vocabs and loading it
locally. Links to the source vocabs downloads can be found in the
middle of this page:

http://vocab.getty.edu/

Mind you, loading the data into a triplestore and setting up a query
infrastructure is a much higher bar than the readily-available query
endpoint the Getty has provided, but it may be faster and, depending on
how the Getty feels about this, nicer to the online sparql service
because you reduce the load on the Getty servers. But I'm not in any
position to advise on the latter; just speculating.

All the best,
Kevin

Thanks you for your advice Kevin. Don't have really much sparql knowledge yet but will look into the option working with a local I instance. I just managed to do simple online queries with python up to now. A while ago I asked in the Google group here if there are any access/query limitations for Getty, but I didn't get any response yet.
Thanks again for your help. Zin
