How to filter by language tag using g.triples in python rdflib?
Question:
I would like to create a dictionary where the keys are the subjects of the triples, and the values are the objects. I am querying a graph (in this example is g) where I have multiples labels, an dI would like to filter only on the english ones. How can I do this?
This is how I am creating the graph at the moment
d = {s: o for s, p, o in g.triples((None, SKOS.prefLabel, None))}
I would expect to add something like but I can’t find the correct syntax.
d = {s: o for s, p, o in g.triples((None, SKOS.prefLabel, None), lang="en")}
Thanks!
Answers:
You could do the filtering by the language tag in your dictionary comprehension like this:
d = {s: o for s, p, o in g.triples((None, SKOS.prefLabel, None))
if o.language == 'en'}
