orthogonal_to relation #5

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

There is a previous discussion on the orthogonal_to relation at [2]. 

In BSPO the property orthogonal_to
 - has domain 'anatomical axis' and range 'anatomical plane'.
 - is not symmetric

My considerations:
 a) In my opinion orthogonal_to has to be a symmetric property. This would require that the domain and range are the same: either both undefined or bot the same class. 
 b) In [2] Melissa said, that they need the existing domain and range definitions. So one solution would be to rename the property to has_orthogonal_complement_in_3D and make it a subproperty of orthogonal_to. But even this property should be symmetric in the ideal case.

What do you think?

Best regards,
Heiner
