RDB structure to RDF mapping

Hi everyone,
I want to formalize in RDF the table structure of a relational database.
What I would like to do is to formalize the links that exists between all
the tables inside a given relational database. This would result in a graph
where the nodes are the tables and the links are the columns that can be
used to join these tables.

My question is: is there some standard/ontology to describe this?

To my understanding the R2RML <https://www.w3.org/TR/r2rml/> ontology is to
describe mappings between RDB and RDF (no RDB structure is mentioned). I
also found a document about direct mapping
<https://www.w3.org/TR/rdb-direct-mapping/> but no ontology is defined in
this document.

Thank you for your help.
