I am trying to make this tutorial http://optique-project.eu/training-programme/module-ontop/

In this step

Import mappings: Ontop>>Import R2RML mappings… <northwind-mapping-M2T2.ttl >

I am waiting more than a hour and no result. This is what it is. And I have no idea whta can I do. enter image description here

The problem comes with the import of mappings.

  • What is the size of the file, and is there any message in the protégé console? – Ignazio Feb 10 '21 at 17:51
  • Using Protégé 5.5 with Ontop 4.2, the mappings loaded fine and in a couple of seconds. I had to edit a little bit the SQL script with the NORTHWIND database, though. – Peter Hopfgartner Jan 24 '22 at 18:04
