Hi! I'm working on a boardgame ontology. My dataset has a variable weight\_categorical with 3 possible values (small, medium, large) - see screenshot [Screenshot by Lightshot](https://prnt.sc/ypplnJpRId5T) My ontology has class:Game hasSize class:Size, which I have mapped like this: [Screenshot by Lightshot](https://prnt.sc/16zlJEwjWj7p) (This works - each Game instance has a size) However, each individual size instance isn't connected to the type Size - see here [Screenshot by Lightshot](https://prnt.sc/P9iaBDb_egGm) Do I really have to create another csv file with index sizeID sizelabel 1 small small 2 medium medium 3 large large ...in order to make the connection between an instance of a Size and its class Size. In the ontology, small, medium and large are all recognized as instances of class Size. ---

Hi Susanne, Yes, to create class instances of Size, you'll need to map directly from a CSV such as bg\_main.csv or a new CSV to the class Size. I've created a project showing this, ![image](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/2X/8/8d12a2543376968c2ad4ee9d36d33428001ed115.png) ![image](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/2X/9/95866cbdf8cbbd7e480e7d09a8666f8118dcb09b.png) ![image](https://canada1.discourse-cdn.com/flex030/uploads/stardog/original/2X/7/7340c6bd982c4483c96c3bba9995d845f69bb478.png) [Size\_type\_class.zip](https://community.stardog.com/uploads/short-url/dCZghMJQj3M8d76BFaAXY0VENQW.zip) (5.8 KB) Thanks, Laura ---
