Adding documentation to an ontology

[Peter]

Dear List
Does anyone have an illustration of adding documentation to an ontology being written using owlready2 - the license, date modified etc.  Also, how in this documentation could I add  blank nodes e.g.

<http://example.org/onto> 
a owl:Ontology;
  dct:creator [
      rdfs:seeAlso <http://peter.me/foaf.ttl> ;
      foaf:name "Peter" ;
    ] ;
  dct:license <https://creativecommons.org/publicdomain/zero/1.0/> ;
  dct:modified "2019-29-30"^^xsd:date ;
.

Hi,

You can use ontology.metadata to access or modify the ontology's metadata.

If you want to create untyped blank node, you can use Thing(0) (the 0 instruct to create it as a blank node).

For example:

from owlready2 import *

onto = get_ontology("http://test.org/onto.owl")

with onto:
    onto.metadata.comment.append("A comment")
    creator = Thing(0)
    creator.seeAlso = "See xxx"
    onto.metadata.comment.append(creator)

Dear Jiba and list

I'm still having a problem in creating blank nodes that are linked via predicates - something like the following:
======================================
<http://www.example.org/myont>
  a owl:Ontology ;
  dct:contributor [
      a foaf:Person ;
      sdo:affiliation [
          foaf:homepage <https://owlready.nabble.com> ;
          foaf:name "Owlready2 Organisation" ;
        ] ;
      rdfs:seeAlso <https://another.org/1234> ;
      foaf:name "Owl Ready" ;
      foaf:workInfoHomepage <http://owlready.org/OWL> ;
    ] ;
.


=======================================

If anyone has any advice on how to code this in owlready2 I would really appreciate it

Hi,

Maybe you should look at RDFlib (which can be used in combination with Owlready). FOAF is not a proper OWL ontology, and blank node are seldomly used as entity in ontologies.
