Missing publication date for Works #86

Closed benedict-tan closed 8 months ago

benedict-tan commented 9 months ago

publicationDate via the documented IRI on the SemOpenAlex website: http://prismstandard.org/namespaces/basic/2.0/publicationDate does not seem to work. It does not seem to be linked to the SemOpenAlex knowledge graph: image

Update: Dmitry has provided me with a workaround, using http://purl.org/dc/terms/date as the predicate for soa:Work. This works fine except that the result is of the format xsd:date instead of xsd:dateTime, which prism:publicationDate would have given.

Hey @benedict-tan,

thank you for pointing this out.

The data incorrectly contains the DatatypeProperty <http://purl.org/dc/terms/date> for Works although <http://prismstandard.org/namespaces/basic/2.0/publicationDate> is defined in the Ontology. We have adjusted this in #90 and in the next version of SemOpenAlex the Works will correctly contain <http://prismstandard.org/namespaces/basic/2.0/publicationDate>, as defined in the Ontology.
