Question

I m trying to get my head around the dbpedia JSON schema and can t figure out an efficient way of extracting a specific node:

This is what dbpedia gives me:

http://dbpedia.org/data/Ceramic_art.json

I ve got the whole thing as a JSON object in Python but don t really understand how to get the english abstract from this data. I ve gotten this far:

u = "http://dbpedia.org/data/Ceramic_art.json"
data = urlfetch.fetch(url=u)
json_data = json.loads(data.content)

for j in json_data["http://dbpedia.org/resource/Ceramic_art"]:
    if(j == "http://dbpedia.org/ontology/abstract"):
        print "it s here"

Not sure how to proceed from here. As you can see there are multiple languages. I need to get the english abstract.

Thanks for your help,

g

Answer 1


print [abstract[ value ] for abstract in json_data["http://dbpedia.org/resource/Ceramic_art"]["http://dbpedia.org/ontology/abstract"] if abstract[ lang ] ==  en ][0]

Obviously, you d want to do more error checking than that, in case the data is bad, but that s the basic idea.

Answer 2

It s a list of dicts. Just iterate through the elements of the list until you find the one whose value for u lang is u en .
