In Quaestor every parameter should have a name, dimension and reference. Below the available dimensions are presented. In addition to the official dimension, an alternative presentation can be created using the @WBDIM attribute.

Please note that Quaestor automatically performs a dimension analysis for relations in the knowledge base. Whether the dimensions on the left and the right side of an expression match, is communicated to the user in the Frame viewer or the Explanation windows. Furthermore, the dimension is used to calculate the proper input based on the DimensionConversion input provided with alternative dimensions.
