Protege-OWL: Class must have one of each <value>

问题

I'm new to protege and i have to model a grid with similar properties to soduku, in Manchester OWL syntax.

I have been searching but i can't seem to find a way to make an axiom that says "each column must have 4 cells, and must have each one of these values ". As in, assuming a 4x1 column, each cell must contain one number and the column must have all the numbers [1:4].

I have already set up some Objects , data properties and Object properties which i will leave here. I will leave the full .owl file here so it can be loaded thus making it easier to give help.

All help is highly appreciated.

EDIT: the point of this is that when i run the reasoner, values to some of the cells, it will infer the values of the other cells. e.x: cell1 = 1, cell2 =2, cell3 = 3 => the reasoner will infer that cell4's value is 4.

Well, try this:

Is it adaptable to your needs? It works with Pellet, not with Hermit.

I have come up with a solution for this project and this question in specific, by changing the approach. Instead of a Cell being a Class that has a Value, it can be done easily by thinking that a Value can be an entity that needs to be placed into a Cell.

Using this line of thinking it can all come down to logic expressions in the axions.

By having a class Value, a data property that adds a value to an individual, and individuals that represent the value with the proper Data property asserted, it can simply be said that, the Cell object (hasvalue value 1) or (hasValue value 2) ... and hasvalue exactly 1 value
