Query Cellar

[kvistgaard]

Currently, Masgui cannot query https://publications.europa.eu/webapi/rdf/sparql due to a CORS error.

https://yasgui.triply.cc/ is able to query Cellar, probably using a backend proxy.

yes, Triply is using a backend proxy to serve CELLAR SPARQL endpoint:

Best course of action is that the internet would stop being stupid and remove CORS on SPARQL endpoints.

I could also setup a backend cors-proxy to offer CORS relieve. But note that:

• It's a best effort promise (no guaranteed availability)
• Privacy will be guaranteed by me but I cannot guaranteed that my infrastructure is not hacked and others gain access to logs or even be able to reroute traffic ***

*** A proxy will always be a privacy/security risk. Credentials pass through it. That includes the Triply and the Sparnatural proxies. I highly advise everyone not to use a third party proxy for which they do not have iron clad guarantees. It is MUCH MUCH MUCH better to host your own CORS proxy, I have a solution for that and am willing to offer free support.
