Re: SHACL shapes for DCAT?

This is not exactly what you want but maybe of interest:

Schemarama codebase at

https://github.com/google/schemarama/
<https://github.com/google/schemarama/blob/main/demo/validation/shex/specific/ServiceB/Dataset.shex>

…gives a validator using shacl and shEx schema.org style in-page structured
data (json-ld, rdfa, microdata). It has boring auto-generated shacl/shex
for the basic structure of Schema.org, alongside product-or-service
specific shapes designed to capture the expressed needs of the
data-consumption ecosystem.

So for datasets it has this rough sketch of the schema.org/Dataset
representation as used in Google Dataset Search:

https://github.com/google/schemarama/blob/main/demo/validation/shex/specific/ServiceB/Dataset.shex


In general the idea is to capture specifics of use rather than try to make
“the” DCAT (or foaf, skos, good relations etc.) shape. One
vocabulary/schema/ontology can support an infinity or quite varied
usecases. This is RDF’s greatest strength and greatest weakness. I still
have hope that Shapes can bridge this gap between expressivity and
usability…
