Is there a known RDF vocabulary for describing metadata of Uri components? (e.g. scheme, authority, querystring, etc.)

Update I have been able to find a DublinCore term resource for URI, but the extent of information communicated in the corresponding RDF document is that "a URI is a DataType", which is much more limited than what I need. The RDF description is below:

<rdf:Description rdf:about="http://purl.org/dc/terms/URI">
    <rdfs:label xml:lang="en">URI</rdfs:label>
    <rdfs:comment xml:lang="en">The set of identifiers constructed according to the generic syntax for Uniform Resource Identifiers as specified by the Internet Engineering Task Force.</rdfs:comment>
    <rdfs:isDefinedBy rdf:resource="http://purl.org/dc/terms/"/>
    <dcterms:issued rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2000-07-11</dcterms:issued>
    <dcterms:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2008-01-14</dcterms:modified>
    <rdf:type rdf:resource="http://www.w3.org/2000/01/rdf-schema#Datatype"/>
    <dcterms:hasVersion rdf:resource="http://dublincore.org/usage/terms/history/#URI-003"/>
    <rdfs:seeAlso rdf:resource="http://www.ietf.org/rfc/rfc3986.txt"/>
</rdf:Description>

    As I'm sure you've discovered, this is a remarkably hard thing to search for using Google, since most descriptions of OWL ontologies mention "IRI", "URI", or "URL." – Joshua Taylor May 03 '13 at 21:24

    @JoshuaTaylor, it's like looking for the solution to a `StackOverflowException` – smartcaveman May 03 '13 at 21:42

w3.org/wiki/URI

I’m not sure what to make of it, but in the w3.org wiki there is a URI page containing a small vocabulary with classes like URI, IRI, Scheme, and UWI. The vocabulary URI for the concept "URI Scheme" would be http://esw.w3.org/topic/Scheme.

CoIN

Related, but probably not exactly what you need, seems to be CoIN (The Composition of Identifier Names):

The CoIN vocabulary defines a set of classes and properties used to descibe what properties of a resource constitute components of a URI.

(See also: URI Templates)

uri4uri.net

There is also uri4uri.net, created as an April fool joke, for:

URIs, URI fragment identifiers, Internet Domains, Mime Types, File Suffixes, URI Schemes.

See the vocabulary at http://uri4uri.net/vocab. It contains URIs for all the relevant URI parts.

An example HTTP URI containing all parts would be: http://foo:bar@bbc.co.uk:80/index.html?a=1&b=2

The generated Turtle includes:

<http://uri4uri.net/uri/http%3A%2F%2Ffoo%3Abar%40bbc.co.uk%3A80%2Findex.html%3Fa%3D1%26b%3D2> 

  rdf:type uriv:URI ;
  skos:notation "http://foo:bar@bbc.co.uk:80/index.html?a=1&b=2"^^<http://www.w3.org/2001/XMLSchema#anyURI> ;
  uriv:scheme <http://uri4uri.net/scheme/http> ;
  uriv:host <http://uri4uri.net/domain/bbc.co.uk> ;
  uriv:port "80"^^<http://www.w3.org/2001/XMLSchema#positiveInteger> ;
  uriv:user "foo" ;
  uriv:pass "bar" ;
  uriv:account <http://uri4uri.net/uri/http%3A%2F%2Ffoo%3Abar%40bbc.co.uk%3A80%2Findex.html%3Fa%3D1%26b%3D2#account-foo> ;
  uriv:path "/index.html"^^<http://www.w3.org/2001/XMLSchema#string> ;
  uriv:suffix <http://uri4uri.net/suffix/html> ;
  uriv:filename "index.html"^^<http://www.w3.org/2001/XMLSchema#string> ;
  uriv:queryString "a=1&b=2"^^<http://www.w3.org/2001/XMLSchema#string> ;
  uriv:query <http://uri4uri.net/uri/http%3A%2F%2Ffoo%3Abar%40bbc.co.uk%3A80%2Findex.html%3Fa%3D1%26b%3D2#query> .

    uri4uri.net was discontinued, which is quite uncool! However, I have started hosting the resolver and vocabulary at https://purl.org/uri4uri/, hopefully available indefinitely. – IS4 Jul 18 '22 at 12:26
