A simple web api that dereferences real world objects in a sparql endpoint following the cool uri's strategy. The api takes a query parameter "uri" and will dereference to the data view or the html view based on accept headers, based on data available in the endpoint.
This is a port of cool-dereferenceable-uris to scala. It has proven its quality in a production setup.
docker run -p 80:8080 --name cool-uri -e SPARQL_ENDPOINT="https://stad.gent/sparql" nvdk/cool-uris:0.1.0
$curl -i https://localhost/?uri=https://stad.gent/id/agents/083b7b32-df2e-4da4-bcc5-b7fe75ea8426
- Step 1 set up a reverse proxy that redirects
https://qa.stad.gent/id/to cool-uris.
The following is an example using nginx and uses the received host and scheme to construct the full uri. 172.24.0.2 is the ip cool-uris is running on.
server {
listen 80;
location /id {
proxy_pass https://172.24.0.2:8080/?uri=$scheme:https://$host$request_uri;
}
}
- Add the necessary information in your SPARQL endpoint
Example triples:
<https://qa.stad.gent/id/visualart/streetart/05c7b793-b387-4b0f-b3da-63c4d3900e76> rdfs:isDefinedBy <https://qa.stad.gent/data/visualart/streetart/05c7b793-b387-4b0f-b3da-63c4d3900e76>

- Test it
$curl -H "Accept: text/turtle" -i https://qa.stad.gent/id/visualart/streetart/05c7b793-b387-4b0f-b3da-63c4d3900e76
should redirect to https://qa.stad.gent/data/visualart/streetart/05c7b793-b387-4b0f-b3da-63c4d3900e76
$curl -H "Accept: text/html" -i https://qa.stad.gent/id/visualart/streetart/05c7b793-b387-4b0f-b3da-63c4d3900e76
should redirect to https://cultuur.qa.stad.gent/node/341
