# RDF::SN(3pm)

Short names for URIs with prefixes from prefix.cc

## NAME

RDF::SN - Short names for URIs with prefixes from prefix.cc

## SYNOPSIS

```
  use RDF::SN;
  $abbrev = RDF::SN->new('20230619');
  $abbrev->qname('http://www.w3.org/2000/01/rdf-schema#type'); # rdfs:type
```

## DESCRIPTION

This module supports abbreviating URIs as short names (aka qualified names), so its the counterpart of RDF::NS.

### new( \[ $ns \] )

Create a lookup hash from a mapping hash of namespace URIs to prefixes (RDF::NS). If multiple prefixes exist, the shortest is used. If multiple prefixes with same length exist, the first in alphabetical order is used.

### qname( $uri )

Returns a prefix and local name (as list in list context, concatenated by `":"` in scalar context) if the URI can be abbreviated with given namespaces.
