==Export==
LexBib wikibase entities with a [[Property:P42|P42 "LexMeta OWL equivalent"]] statement are considered for the export. Their rdf:type is declared using the value of that statement's [[Property:P166|P166 "rdf:type (OWL)]] qualifier. If for that statement a [[Property:P167|P167 "skos:exactMatch"]] qualifier is found, that is also exported (that tipically points to the FRBR, MetaShare, or BIBO equivalent of the entity, see [[LexMeta]]). For classes, "subclass of" ([[Property:P4|P4]]), and for properties, "subproperty of" ([[Property:P169|P169]]) are also considered. Property "domain" ([[Property:P168|P168]]) and "range" ([[Property:P48|P48]]) are declared as separate statements, while "range" (in cases where the OWL range expression is complex) can be expressed using a [[Property:P170|P170]] "OWL range expression" qualifier (this is done where the range is a concept scheme, see e.g. [[Property:P127|P127]]).

* Their rdf:type is declared using the value of that statement's [[Property:P166|P166 "rdf:type (OWL)]] qualifier.  
Other statements for these entities are exported in case the LexBib wikibase property is also aligned (using [[Property:P42|P42]]) to a LexMeta OWL equivalent. The claim value, that is, the value of the wikibase property used in the /prop/direct/ namespace, is what is exported as value for the OWL equivalent property. Statements pointing to other LexBib wikibase items are exported only if the object is also aligned to LexMeta OWL. Other properties are mapped to datatype properties. [[Property:P2|P2 "Wikidata Entity"]] statements and the LexBib wikibase entity URI itself are mapped to an object property called "lexmeta:wikibaseEntity".
