Does anyone know where to find a package or example code to read and write turtle files containing RDF or OWL ontologies? There is a package (JuliaPackageMirrors/RDF.jl: Julia package mirror.), but it has not been updated recently.
Something equivalent to the Python rdflib.
The idea is to read these files into a julia Graph or save from a Graph object.
@kobusherbst , could this help a bit better: GitHub - epatters/Serd.jl: Julia bindings to Serd RDF library ?
This is from @epatters who I know is extremely active in Julia world.
Thank you, I will definitely give it a try. Serd is being actively maintained as well. It is certainly a cleaner option for me than using Python’s rdflib.
Glad to hear it! Feel free to share how you end up using it or any examples you think or fun – I’d love to see what you get up to here! 
I have delved a bit deeper into the Serd.jl package. Unfortunately, it is stuck at an old version of the Serd C library, which is still being updated regularly. I have looked at what it would take to update Serd.jl myself, but the C library build manager have changed, and after wrestling with it, I was unable to build the updated _jll package to incorporate the latest version of the package.
Serd.jl itself requires updates as well, e.g. currently it doesn’t support xsd:Date type, this fix I can do myself, but I prefer doing that against the latest version of the C library.
I would be grateful if anyone could help me to build the Serd_jll package using the latest version of the C library
