Mapping classes

@rdf_entity

Maps a Python class to an RDF type. The class must have a uri attribute that identifies the RDF subject.

@mapper.rdf_entity(EX.Person)
class Person:
    def __init__(self, uri, name: str):
        self.uri = uri
        self._name = name

@rdf_property

Maps a Python property to an RDF predicate. The property name must match the private attribute (prefixed with _).

@mapper.rdf_property(FOAF.name, minCount=1, maxCount=1)
def name(self): pass

Parameter	Description
predicate_uri	URI of the RDF predicate
minCount	Minimum cardinality for SHACL (default: 0)
maxCount	Maximum cardinality for SHACL (default: 1)

Supported Python types

rdfmapper automatically converts Python values to RDF Literals with the correct datatype:

Python type	RDF datatype
bool	xsd:boolean
int	xsd:integer
float	xsd:double
datetime.datetime	xsd:dateTime
datetime.date	xsd:date
str	xsd:string
