How is the role of a crystallographic model best expressed in EMMO? #17

OK, so some more thoughts. A crystallographic model has parameters that have been optimised. We use a semiotic process to assign values that we find in data files to values of these parameters. Similarly, these parameters are interpreted as concepts in the physicalistic perspective, e.g. unit cell lengths, allowing us to assign unit cell lengths to a real-world material. |

As EMMO doesn't allow abstract concepts, we need to describe the meaning of derived data found in CIF files and databases using the terms that are available. In particular, we have available the semiotic process to link mathematical equations with other objects and the data perspective.
The infinite crystal model on which the mathematics is based cannot be a part of the physicalistic perspective as no such thing exists, so I'm inclined now not to try to incorporate that into the ontology. The unit cell as a repeating unit in a material is something we think exists, on average, so is that something we can, in fact, include in the physicalistic perspective?
Is anyone able to produce an example from another EMMO domain ontology where refined parameters from a mathematical model are described in the ontology? Particularly interested in whether @jesper-friis or @emanueleghedini can help on this one.
