Upload File to artifact in RDNG using OSLC
Accepted answer
This is called a "wrapped resource" when such file is uploaded to RDNG. You will have a wrappedResource link pointing to the exact file stored in the repository, and another "normal" artifact with this link embedded in it. You can see the below post with some similar discussion.

I'm not aware of any method in OSLC to allow you to upload a file, regardless its type.
