When I try to do a LOAD, e.g.:
LOAD <file:///Users/andreaw/Documents/tests/manifest.ttl> INTO GRAPH <tests>
It fails. The stack trace implies that it is always using the HTTP client, but the file reference is a valid authority (and Stardog acknowledges this).
Is this a bug or am I misunderstanding something?

The entire query is sent to the server and the file is dereferenced there so it’s looking for that file on the server and I’m guessing from the file path it’s on your client. If the server and client are running on the same machine it would need to be accessible by the user that the server is running as. You can try copying the file into /tmp and changing the owner and/or permissions.
The error doesn’t seem ideal but it’s from the cli so the real cause might be obscured. You’ll probably get a better idea of what the real cause is by looking at the server logs.
I ended up modifying the code to LOAD files from an HTTPS address.
Thanks for the help.
