URI patterns
The dataset uses URIs of the form:
For entities, i.e. persons and organizations: https://isni.org/isni/{ISNI} where ISNI is the 16 digit identifier. For example, https://isni.org/isni/0000000080456315
https://isni.org/isni/{ISNI} identifies the entity, i.e. the person or organization
https://isni.org/isni/{ISNI}/about identifies the description of the entity
https://isni.org/isni/{ISNI}/about.{ext} , for example https://isni.org/isni/{ID}/about.rdf identifies the RDF/XML description of the entity
For metadata terms in the ISNI ontology, https://isni.org/ontology#{term}. For example, https://isni.org/ontology#hasDeprecatedISNI
Data model
Person
| RDF property | Expected value/range | Definition | Cardinality |
|---|---|---|---|
| rdfs:label | Literal | 16 digit ISNI presented as stated in the ISNI ISO standard, e.g. ISNI 0000 0000 8045 6315 | 1 |
| rdf:type | Class | Always schema:Person | 1 |
| schema:alternateName | Literal | Name of the public identity | 1..* |

| schema:deathDate | Literal | Year of death of the public identity | 0..1 |
| schema:identifier | Class | Always schema:PropertyValue | 1 |
| isni:hasDeprecatedISNI | Literal | Deprecated ISNI; 16 digits with no space | 0..* |
| owl:sameAs | Class | Entity identified by a URI and modelled as a real world object | 0..* |
| madsrdf:isIdentifiedByAuthority | Class | Entity identified by a URI and modelled as an authority/skos:Concept | 0..* |
| dcterms:source | Class | Entity identified by a non machine actionable URI, i.e. a URL | 0..* |
Organization
| RDF property | Expected value/range | Definition | Cardinality |
|---|---|---|---|
| rdfs:label | Literal | 16 digit ISNI presented as stated in the ISNI ISO standard, e.g. ISNI 0000 0001 2353 1945 | 1 |
| rdf:type | Class | Always schema:Organization | 1 |
| schema:alternateName | Literal | Name of the public identity | 1..* |
| schema:identifier | Class | Always schema:PropertyValue | 1 |
| isni:hasDeprecatedISNI | Literal | Deprecated ISNI; 16 digits with no space | 0..* |
| owl:sameAs | Class | Entity identified by a URI and modelled as a real world object | 0..* |
| madsrdf:isIdentifiedByAuthority | Class | Entity identified by a URI and modelled as an authority/skos:Concept | 0..* |
| dcterms:source | Class | Entity identified by a non machine actionable URI, i.e. a URL | 0..* |
Property Value
Always a blank node
| RDF property | Expected value/range | Definition | Cardinality |
|---|---|---|---|
| rdf:type | Class | schema:PropertyValue | 1 |
| schema:propertyID | Class | Always the Wikidata identifier for the ISNI schema, i.e. http://www.wikidata.org/entity/Q423048 | 1 |
| schema:value | Literal | 16 digit ISNI – no blank spaces | 1 |
Expressing deprecation
The model uses the isni specific property isni:hasDeprecatedISNI , for example:
<https://isni.org/isni/0000000121394035> isni:hasDeprecatedISNI "000000012407618X" .
where ISNI 0000 0001 2407 618X is is the deprecated ISNI for the entity with the assigned ISNI 0000 0001 2139 4035
In addition to the isni:hasDeprecatedISNI property, the following construct is also used:
owl:deprecated "true”^^xsd:Boolean" ;
rdfs:comment "this identifier is deprecated. See rdfs:seeAlso link for new identifier" ;
rdfs:seeAlso <https://isni.org/isni/0000000121394035> .
Linking to external resources
The model uses three different properties to establish relationships with external resources:
owl:sameAs if the external resource has been modelled as a real world object (RWO). For example, Wikidata resources identified by URIs with the pattern http://www.wikidata.org/entity/{ID}
madsrdf:isIdentifiedByAuthority if the external resource has been modelled as an Authority, i.e. a document about a Thing rather than the Thing itself. For example, data.bnf.fr resources identified by URIs with the pattern http://data.bnf.fr/{ID}
dcterms:source if the URI is a URL, i.e. points to a webpage with no machine actionable data.
The dataset currently includes links to: data.bnf.fr, wikidata, musicbrainz, National Library of Korea resources and National Asssembly Library of Korea, where they exist in the ISNI database.
