That is a commonly used distinction:    (02)

MB> A distinction I find useful (though not very formal) is that

See below for the opening paragraph of one of my tutorials on
ontology.  The final section of that tutorial is a glossary.    (04)

1. What is Ontology?    (07)

The subject of _ontology_ is the study of the categories of things that 
exist or may exist in some domain.  The product of such a study, called 
_an ontology_, is a catalog of the types of things that are assumed to 
exist in a domain of interest D from the perspective of a person who 
uses a language L for the purpose of talking about D.  The types in the 
ontology represent the predicates, word senses, or concept and relation 
types of the language L when used to discuss topics in the domain D. An 
uninterpreted logic is ontologically neutral:  It imposes no constraints 
on the subject matter or the way the subject is characterized.  By 
itself, logic says nothing about anything, but the combination of logic 
with an ontology provides a language that can express relationships 
about the entities in the domain of interest.    (08)
