I would have to review the whole SWEET approach in general, but at least in this case, it seems to me that repr:1D, repr:2D and repr:3D should be instances and not classes themselves: you wouldn't be creating instances of repr:1D for example.

Perhaps something like this would be more appropriate?

repr:1D rdf:type repr:Representation ,
                       [ rdf:type owl:Restriction ;
                         owl:onProperty mrela:hasDimension ;

                       ] .

First a pragmatic question: would this affect any existing infrastructure that uses sweet and hardcodes certain assumptions about everything being classes, and subClassOf being the main linking predicate? For example, would this cause 1D to drop out of some ontology browser displays?

But I think we also need a definition of 1D and some use cases showing how it gets used. This is where an upper ontology can help. While I think BFO can be a little abstruse at times, it does provide a framework for distinguishing things like variables vs projections in space etc. Going along with this, I think 1D is too short a name for a class, because I don't know from the name what it is. Is it literally the value for a unit "dimension" or can it be used for a 1D entity (e.g a conceptual line between Glasgow and Edinburgh)...?

rdfs:comment "Extraneous variables are 'extra' variables that may influence the outcome of an experiment but aren't taken into account during measurement. Ideally, these variables won't impact the final conclusion drawn by the experiment, but they may introduce error into scientific results. Examples of extraneous variables include accidents, factors you either can't control or can't measure or factors you consider unimportant. Every experiment has extraneous variables. Example: You are conducting an experiment to see which paper airplane design flies longest. You may consider the color of the paper to be an extraneous variable. You note in your lab book that different colors of papers were used. Ideally, this variable does not affect your outcome."@en .
