importing ontologies without aeon:SMW_datatype

[andrecastro0o]

Currently ontology2smw import to wiki only the terms which contain a value to the property aeon:SMW_datatype as visible in SPARQL query_classes_properties.rq

I would like to make ontology2smw able to import other ontologies terms, even if they do not have aeon:SMW_datatype, as for instance datacite datacite ttl OR GND Ontology (gndo) gndo ttl

Development Steps

• SPARQL query: to extract information from ontology terms
• Test ontology query
• Mapping xsd datatypes to SMW datatypes
• All namespaces & prefix dict, derived from http://prefix.cc/
• Prompt user for prefix when not found in all prefixes dict
• Implement

Find the datatypes

is rdf:type value always a owl:XYZ ?

Or do ontology designers use other strategies to define a term as class / DatatypeProperty / ObjectProperty?

determine Has type:: without aeon:SMW_datatype

The main issue is how to determine from the terms definition the SMW Has type:: property of a Property definition

In ontology schema rdf:type is use to define if a terms is:

• owl:Class -> SMW: Category
• owl:AnnotationProperty -> SMW: Has type::Text
• owl:ObjectProperty -> SMW: Has type::Page
• owl:DatatypeProperty -> SMW: Has type:: ???

https://www.w3.org/TR/2004/REC-owl-guide-20040210/#owl_DatatypeProperty show the recommended xsd datatypes for use with owl:DatatypeProperty, plus rdfs:Literal

where is datatype defined?

In rdfs:range: the range of values given to a DatatypeProperty are X

###  https://github.com/tibonto/aeon#ID_URL
aeon:ID_URL rdf:type owl:DatatypeProperty ;
            rdfs:subPropertyOf aeon:ID ;
            rdfs:domain aeon:Identifier ;
            rdfs:range xsd:anyURI ;

###  http://rs.tdwg.org/abcd/terms/acquisitionSourceText
:acquisitionSourceText rdf:type owl:DatatypeProperty ,
                                owl:FunctionalProperty ;
                       rdfs:domain owl:Thing ;
                       rdfs:range xsd:string ;

dcat:bbox
  a rdf:Property ;
  a owl:DatatypeProperty ;
  rdfs:domain dct:Location ;
  rdfs:label "bounding box"@en ;
  rdfs:range rdfs:Literal ;

dcat:spatialResolutionInMeters
  a owl:DatatypeProperty ;
  rdfs:range xsd:decimal ;

###  http://xmlns.com/foaf/0.1/age
:age rdf:type owl:DatatypeProperty ,
              owl:FunctionalProperty ;
     rdfs:domain :Agent ;
     rdfs:range rdfs:Literal ;
