Since I use protege/ontop to define mappings, I have an r2rml file for my postgres database, which I wanted to use in Stardog Studio to no avail, since it only accepts SMS2. Is there a way import an r2rml file to a database in a Stardog Free account, or to convert an r2rml file to SMS2?
Hi. You can use R2RML files for import. In Studio, create you PostgreSQL data source, then use the stardog-admin CLI to create the virtual graph. This is off the top of my head but it's something like (check the docs)
If I leave out the mapping file from the command, then Stardog creates the virtual graph no problem. The "-v" option did not really give any meaningful addition to the error message. Is there a way to somehow get to the bottom of this, because I don't really get what the problem is.
