RDF Schema for org-mode

Question

I would like to create an RDF schema world for org-mode. As you may know, an org-mode document is based on an hierarchical outline where headings are the main grouping entities.

* March auxiliary
:PROPERTIES:
:HLEVEL: 1
:END:

** :TOGRO: json/rdf grokking
:PROPERTIES:
:HLEVEL: 2
:END:

*** :GROKKING: json grokking intro 
:PROPERTIES:
:HLEVEL: 3
:END:

*** :GROKKING: test of simple worg snippet
:PROPERTIES:
:HLEVEL: 3
:END:

Probably the best view/breakdown of this is an org-element parse of an org-mode file. (See here. Brace yourself for ads.) In my schema, each "HLEVEL" would have a URI noun. I've not heard of an RDF schema for org-mode, so I guess I need to know if there is any sort of URI "upstream" from a URI I might create, e.g., http://example.org/org-mode-hlevel-1 is a sub-node/special type of of an existing, established URI for, in general, document hierarchy nodes. Is there an existing schema for documents that are in a hierarchical outline format that I can start with, work down from? Then I'd probably need a whole URI noun vocabulary for the TODO wilderness. Then one for the Babel world, especially the metaprogramming. What I envision is an org-element sort of parser that would generate OWL, N-triples.

Actually, Roam Research already has the rudiments of what I'm eventually aiming at. See this video. This is what I'm aiming at.

I'd use blank nodes for headings etc, not URIs... As for the 'heading' class, see https://lov.linkeddata.es/dataset/lov/terms?q=heading&type=class — Stanislav Kralin, Mar 04 '20 at 19:02

I just learned about :CUSTOM_ID" in org-mode, which looks like a good way to assign identity to org mode text. So, for example, in somefile.txt,

* TODO my heading
   :PROPERTIES:
   :CUSTOM_ID: id432
   :myProp:   vanilla
   :END:

could end up as

@prefix ex: <http://www.somedomain.com/ns/ex> . 

<somefile.txt#id432> dc:title "my heading" ; 
                     ex:status "TODO" ;
                     ex:myProp "vanilla" .
