Nice work!

BTW -- could you add some rdfs:isDefinedBy relations to your ontology? 
This makes the ontology description graph much more navigable using 
follow-your-nose pattern.

If you have a SPARQL 1.1 database/store at your disposal it boils down to:

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX wdrs: <http://www.w3.org/2007/05/powder-s#>
PREFIX vocab: <http://open.vocab.org/terms/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

LOAD <http://lemon-model.net/lemon.ttl> ;

INSERT {GRAPH <http://lemon-model.net/lemon.ttl>
             {    ?s rdfs:isDefinedBy <http://www.lemon-model.net/lemon#> .
                 <http://www.lemon-model.net/lemon#> vocab:defines ?s .
                 <http://www.lemon-model.net/lemon#> a owl:Ontology .
                 ?s wdrs:describedby <http://lemon-model.net/lemon.ttl> .
                 <http://lemon-model.net/lemon.ttl> foaf:primaryTopic ?s .
             }
         }
WHERE {GRAPH <http://lemon-model.net/lemon.ttl> {
                                                 {?s rdfs:subClassOf ?o}
                                                 UNION
                                                 {?s rdfs:subPropertyOf ?o}
                                                 UNION {?s 
owl:equivalentClass ?o}
                                                 UNION {?s 
owl:equivalentProperty ?o}
                                                 UNION {?s a ?o}
                                             }
     }

I've applied the relations in question to some of our instances [1].
