Looking closer, my feeling is that the terms at the top of column 1 are subclasses of Expression: :Abridgment rdfs:subClassOf :Expression . :Revision rdfs:subClassOf :Expression . :Translation rdfs:subClassOf :Expression . :Arrangment rdfs:subClassOf :Expression . The Expression-to-Expression relationship properties listed below would presumably have these domain/range settings: :hasAnAbridgment rdfs:domain :Expression ; rdfs:range :Abridgment . :hasARevision rdfs:domain :Expression ; rdfs:range :Revision . :hasATranslation rdfs:domain :Expression ; rdfs:range :Translation . :hasAnArrangement rdfs:domain :Expression ; rdfs:range :Arrangement . :isAnAbridgmentOf owl:inverseOf :hasAnAbridgment . :isARevisionOf owl:inverseOf :hasARevision . :isATranslationOf owl:inverseOf :hasATranslation . :isAnArrangementOf owl:inverseOf :hasAnArrangment. You COULD capture the information in table 5.3 in property fields of the Expression, but then we're back to our brains falling out. The terms in column 3 appear be subclasses of those, but probably don't justify being pulled out separately.
