Is a URC (Uniform Resource Citation) synonymous with a Query String or Url Parameters?

Question

Reading this:

https://renenyffenegger.ch/notes/development/web/URI-URL-URN-IRI-URC

URCs provide a set of attribute/value pairs that describe properties of URIs like authorship, publisher, copyright etc.

Is that synonymous with the query string found in here:

https://stackoverflow.com/questions/ask?authorship=foo&publisher=bar&copyright=etc

namely, could

?authorship=foo&publisher=bar&copyright=etc

be considered the URC?

Answer 1

I gather from Wikipedia's Uniform Resource Characteristic article (and references in that article) that URCs are properties embedded (contained) within the specific resource.

So when you fetch a web page, for example, the page's URC might be embedded in the page using <meta> elements.

But URCs were never standardised/implemented (so they're not in fact uniform).
