The issue is one of orthographic representations, that is spelling variants
between languages (e.g., theatre and theater) but more particularly also
the issue of pronunciation guides such as /ˈθiːətə(ɹ)/.

More particularly the mapping should be to lexical entries, I believe,
because they represent the core element of the OntoLex model, so it seems
natural to link there. This means of course that the properties I propose
do not give a one-to-one correspondence between SKOS and OntoLex but
instead that they give a good guideline for how people can fix up their
SKOS(-XL) model to be linguistically sound

John
