Improve namespacing?

Overview

I'm using OMOP for concept IDs and omoprel for relationships. But I'm also using OMOP for omop table properties, e.g. concept_class_id in the example below. Maybe use something else, like omopproperty?

<owl:Class rdf:about="https://athena.ohdsi.org/search-terms/terms/709741">
    <rdfs:label rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Excision of chest wall tumor involving rib(s), with plastic reconstruction</rdfs:label>
    <OMOP:concept_class_id rdf:datatype="http://www.w3.org/2001/XMLSchema#string">CPT4 Hierarchy</OMOP:concept_class_id>

Ian Braun is also doing similar work, and he was going to use omoptype for something. I don't remember what that was, but maybe there's something I overlooked where this could be utilized.
