EPOS-RDF Classes

EPOS-RDF Classes can be called with an identifier, dictionary or both. A class can be registered within the RDF graph using the .register method. Multiple classes can be nested in the dictionaries. Input is checked against the shapes contraint file (shacl).

Call	Result
Class(identifier)	Reference
Class(dictionary)	Blank Node
Class(identifier, dictionary)	Graph Node

To extract the RDF call the serialize() method. The default format is "turtle".

Python - EPOSRDF Mapping

Python native types are mapped to RDF types using the following conversion table.

Native Type	RDF Type
datetime.datetime	xsd.datetime
datetime.date	xsd.date
str, unicode	xsd.string
boolean	xsd.boolean
int	xsd.integer
float	xsd.float
URI http(s)://	xsd.anyURI
list	Recursive type mapping

Example Usage

from classes.EPOS import EPOSRDF
from classes import *

R = EPOSRDF()

Org = Organization("PIC:997012076", {
  "epos:legalContact": Person("http://orcid.org/0000-0001-7750-7254"),
  "schema:address": PostalAddress({

  })
})

R.register(Org)
