SSN example: Can't find QuantityValue in qudt-1.1 vocabulary

[miranda-zhang]

In the examples of documentations there are many usage of qudt-1.1:QuantityValue
I searched in http://qudt.org/1.1/schema/qudt#
It seems there is only a property http://qudt.org/schema/qudt#quantityValue
But no class named "QuantityValue"?

Example 1 in doc https://www.w3.org/TR/vocab-ssn/#iphone_barometer-sosa

   sosa:hasResult [
      a qudt-1-1:QuantityValue ;
      qudt-1-1:unit qudt-unit-1-1:DegreeCelsius ;
      qudt-1-1:numericValue "-29.9"^^xsd:double ] .

@dr-shorthair could you take a look?

Indeed, the description of classes qudt-1.1:QuantityValue and qudt-1.1:Quantity is not available at their own URIs. Instead, they are defined in the ontology http://qudt.org/1.1/schema/quantity#

[dr-shorthair]

Indeed, they can also be found in http://qudt.org/1.1/schema/OSG_quantity-(v1.1).ttl

QUDT has somehow not achieved 'linked data' status for their URIs ... However, strictly that does not mean they can't be mentioned elsewhere.

BTW - the gateway to QUDT resources is just http://qudt.org

@miranda-zhang - do these responses answer your question? If so, please would you confirm & then close this issue. Many thanks.

Thank you, everyone!
By the way, I end up using https://schema.org/TypeAndQuantityNode rather than qudt-1-1:QuantityValue
