Unknown IO error - Not a valid HTTP URI

[BorderCloud]

Hello

The TTL files of W3C's tests via queries "LOAD" create several errors.
Say me, if you have an idea.

You can reproduce these errors with this project : https://github.com/BorderCloud/tft-4store

Hi, I checked the MIME type of the Turtle files served by GH and it's correct. Could you please try against some non-HTTPS server? Or import from file? Just to rule out the parsing problems and cURL TLS settings.

Also, you are aware that 4store does not fully support SPARQL 1.1 but SPARQL 1.0 only?

Karima, is that you? Cheers from SSSW'16 👋

[BorderCloud]

Yes it's me ;) (BorderCloud is my account GitHub)

I knew that 4Store does not support 1.1 fully.
I think 4store not support LOAD. I wanted to have confirmation.
May be a future enhancement ;)

Thanks
Bye bye !

From the sources it looks there is LOAD support:

4store/src/frontend/update.c

Line 230 in fe34829

case RASQAL_UPDATE_TYPE_LOAD:

The error messages make it sound like it's HTTP only, not HTTPS.

SPARQL 1.1 support is pretty partial though.

[BorderCloud]

Github does automatically the redirection http to https. I cannot change it (simply).

[swh]

4store uses the raptor graph ingestion code, which appears to only support HTTP. There might be some configuration to add HTTPS? Not sure.
