While you wait for the easier RDF, please try out Reasonable Ontology
Templates (OTTR). OTTR templates are like macros for RDF. They can be
nested (a template can be built from other templates) and be
instantiated. A template instance can be expanded to RDF triples. There
are different serialisations, one in RDF. For example, the instance
[] ottr:templateRef <http://draft.ottr.xyz/pizza/NamedPizza> ;
ottr:withValues ( ex:Margherita ex:Italy ( ex:Mozzarella ex:Tomato )) .
expands to
ex:Margherita rdf:type owl:Class ;
rdfs:subClassOf p:NamedPizza ,
[ rdf:type owl:Restriction ;
owl:onProperty p:hasTopping ;
owl:someValuesFrom ex:Mozzarella
] ,
[ rdf:type owl:Restriction ;
owl:onProperty p:hasTopping ;
owl:someValuesFrom ex:Tomato
] ,
[ rdf:type owl:Restriction ;
owl:onProperty p:hasTopping ;
owl:allValuesFrom [
rdf:type owl:Class ;
owl:unionOf ( ex:Mozzarella ex:Tomato )
]
] ,
[ rdf:type owl:Restriction ;
owl:onProperty p:hasCountryOfOrigin ;
owl:hasValue ex:Italy
] .
with the NamedPizza template defined as seen here:

For more information please check out:

- ISWC demo: https://www.ottr.xyz/resource/demo/2018-10-08-iswc/
- Papers: https://www.ottr.xyz/#Publications
The current implementation is a proof of concept. Updated specifications
and implementation will be released in the coming months.
