An example of how to connect to the LINDAS service with the R package for SPARQL
| library(SPARQL) | |
| endpoint <- "https://lindas.admin.ch/query" | |
| rdf_query <- " | |
| PREFIX : <http://voc.zazuko.com/zack#> | |
| PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> | |
| PREFIX wdt: <http://www.wikidata.org/prop/direct/> | |
| PREFIX gont: <https://gont.ch/> | |
| SELECT DISTINCT ?Haltestelle WHERE | |
| { GRAPH <https://linked.opendata.swiss/graph/FOT/didok> { | |
| ?sub gont:municipality ?municipality . | |
| ?sub ?pred ?obj . | |
| } | |
| ?didok rdfs:label ?Haltestelle | |
| } LIMIT 100 | |
| " | |
| myOpts <- curlOptions(sslversion=1.2) | |
| res <- SPARQL(endpoint, rdf_query, curl_args=myOpts) | |
| df <- res$results | |
