Re: polymorphic RDF mapping

Hi,

Are you looking for a mapping tool and mapping language which transforms 
this JSON into RDF?

There are many of those, the most popular ones are based upon RML, but 
there are also some SPARQL and ShEx based ones.
A full overview can be found in this survey:

Declarative RDF graph generation from heterogeneous (semi-)structured 
data: A systematic literature review by Van Assche et al. 
https://doi.org/10.1016/j.websem.2022.100753 
<https://dylanvanassche.be/assets/pdf/systematic-review-of-mapping-languages.pdf>

A popular RML mapping engine is RMLMapper 
<https://github.com/RMLio/rmlmapper-java> with RML as mapping language 
which can transform this JSON into RDF (and many other data 
formats/sources).
RML is currently being standardized at the W3C Community Group on 
Knowledge Graph Construction, so there are 2 versions of RML (original 
<https://rml.io/specs/rml/>, W3C CG <https://w3id.org/rml/portal/>) at 
this moment until the standardization process is over.
RMLMapper supports both and also R2RML.

Kind regards,
Dylan Van Assche
