rdfox-rs

Embedded Oxford Semantic Technologies RDFox database for Rust programs.

Downloads RDFox zip file (to your target directory)
Generates bindings from CRDFox.h using bindgen (which requires llvm to be installed)
Links to dynamic link library libRDFox.dylib (if you use feature rdfox-dylib)
Links to the static RDFox library by default
Requires an RDFox license (see https://www.oxfordsemantic.tech/product)
- Copy license to ~/.RDFox/RDFox.lic
Provides a higher level rust-friendly interface over the C-API

Status

All the basics work
Currently only supports RDFox 6.2
RDFox itself, a C/C++ program. comes as a dynamic link library or a static library, both of which are supported by this Rust crate.
- Use feature rdfox-dylib if you want to use the dynamic link library
- At the moment, the static link library causes a SEGSEGV signal when running the tests. This is being investigated.
- Therefore, this crate is not ready for production yet.
Has only been tested as an embedded database (meaning: running the whole RDFox database engine in your Rust process), however, in theory it should also be possible (with some tweaks that we have to add) to run it just as a client to a remote instance of RDFox.
RDFox API logging does not work when linking with static library (issue in progress)

Get the static link library to not cause a SIGSEGV signal
Make high-level interface more abstract so that it can also be used for remote endpoints using REST calls and potentially any other triple store product.
- Core components that are RDFox-independent have already been moved to the rdf-store-rs crate

The major/minor version numbers of this crate are used to determine which version of RDFox needs to be downloaded and used.

shell RUST_LOG=info cargo test

Or, if you want to see all output:

shell RUST_LOG=trace cargo test --package rdfox-rs --test load load_rdfox -- --exact --nocapture

If you want to run the tests with the dynamic link library of RDFox, then run this:

shell RUST_LOG=trace cargo test --package rdfox-rs --features rdfox-dylib --test load load_rdfox -- --exact --nocapture
