Use sophia to connect to a SparQL db (in my case AnzoGraph) #97

Hi!

Thank you for this library!

I am working on a graphQL -> sparQL translator in Rust (https://github.com/007vasy/warpgrapher?organization=007vasy&organization=007vasy) and I having a hard time figuring out how to use sophia to connect to a database and execute the queries againts it. Could you give some pointers?

Hi @007vasy and thanks for your interest. No wonder you didn't find how to do it: there is currently no implemenation of a SPARQL-protocol client in Sophia... :-/ But I'll add this to my TODO list.

@pchampin that is great to hear! Is there anything what I can assist you with? I am not a Rust expert, however if you give me some pointers I will try to help and assist. (I have developed a graphQL endpoint for Anzograph which uses SparQL protocol in a JS)

https://github.com/007vasy/rust-sparql-client/blob/main/src/main.rs this is a bare bones code, however with anzograph it could be used as base for a sparql client for anzograph (I made it work with that db)

I have a first version of a a SPARQL client for Sophia here: https://github.com/pchampin/sophia_sparql_client

It is not on crates.io yet because it relies on the SparqlDataset trait which is only available in the github version of Sophia at the moment, but I'll release it at the same time as the next version of Sophia.

In the meantime, you can still use it directly from github: https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories
