Overview

A Uniform Resource Identifier (URI). Also compatible with International Resource Identifier (IRI)

en.wikipedia.org/wiki/Internationalized_Resource_Identifier

Examples:

Creating a URI reference (1)

uri = RDF::URI.new("http://rubygems.org/gems/rdf")

Creating a URI reference (2)

uri = RDF::URI.new(scheme: 'http', host: 'rubygems.org', path: '/gems/rdf')
  #=> RDF::URI.new("http://rubygems.org/gems/rdf")

Creating an interned URI reference

uri = RDF::URI.intern("http://rubygems.org/gems/rdf")

Getting the string representation of a URI

uri.to_s #=> "http://rubygems.org/gems/rdf"

def self.cache
  require 'rdf/util/cache' unless defined?(::RDF::Util::Cache)
  @cache ||= RDF::Util::Cache.new(CACHE_SIZE)
end

.intern(*args) ⇒ RDF::URI

Returns an interned ‘RDF::URI` instance based on the given `uri` string.

The maximum number of cached interned URI references is given by the ‘CACHE_SIZE` constant. This value is unlimited by default, in which case an interned URI object will be purged only when the last strong reference to it is garbage collected (i.e., when its finalizer runs).

Excepting special memory-limited circumstances, it should always be safe and preferred to construct new URI references using ‘RDF::URI.intern` instead of `RDF::URI.new`, since if an interned object can’t be returned for some reason, this method will fall back to returning a freshly-allocated one.

Returns:

  • (RDF::URI) —

    an immutable, frozen URI object

end

.normalize_path(path) ⇒ String

TODO:

This process is correct, but overly iterative. It could be better done with a single regexp which handled most of the segment collapses all at once. Parent segments would still require iteration.

Resolve paths to their simplest form.

Parameters:

  • path (String)

Returns:

  • (String) —

    normalized path

.parse(str) ⇒ RDF::URI

Creates a new ‘RDF::URI` instance based on the given `uri` string.

This is just an alias for #initialize for compatibity with ‘Addressable::URI.parse`. Actual parsing is defered until #object is accessed.

Parameters:

  • str (String, #to_s)

Returns:

#+(other) ⇒ RDF::URI

Simple concatenation operator. Returns a URI formed from concatenating the string form of two elements.

For building URIs from fragments, you may want to use the smart separator, ‘#/`. `#join` implements another set of URI building semantics.

Examples:

Concatenating a string to a URI

RDF::URI.new('http://example.org/test') + 'test'
#=> RDF::URI('http://example.org/testtest')

Concatenating two URIs

RDF::URI.new('http://example.org/test') + RDF::URI.new('test')
#=> RDF::URI('http://example.org/testtest')

Parameters:

  • other (Any)

Returns:

#/(fragment) ⇒ RDF::URI

‘Smart separator’ URI builder

This method attempts to use some understanding of the most common use cases for URLs and URNs to create a simple method for building new URIs from fragments. This means that it will always insert a separator of some sort, will remove duplicate seperators, will always assume that a fragment argument represents a relative and not absolute path, and throws an exception when an absolute URI is received for a fragment argument.

This is separate from the semantics for ‘#join`, which are well-defined by RFC3986 section 5.2 as part of the merging and normalization process; this method does not perform any normalization, removal of spurious paths, or removal of parent directory references `(/../)`.

See also ‘#+`, which concatenates the string forms of two URIs without any sort of checking or processing.

For an up-to-date list of edge case behavior, see the shared examples for RDF::URI in the rdf-spec project.

Examples:

Building a HTTP URL

RDF::URI.new('http://example.org') / 'jhacker' / 'foaf.ttl'
#=> RDF::URI('http://example.org/jhacker/foaf.ttl')

Building a HTTP URL (absolute path components)

RDF::URI.new('http://example.org/') / '/jhacker/' / '/foaf.ttl'
#=> RDF::URI('http://example.org/jhacker/foaf.ttl')

Using an anchored base URI

RDF::URI.new('http://example.org/users#') / 'jhacker'
#=> RDF::URI('http://example.org/users#jhacker')

Building a URN

RDF::URI.new('urn:isbn') / 125235111
#=> RDF::URI('urn:isbn:125235111')

Parameters:

  • fragment (Any) —

    A URI fragment to be appended to this URI

Returns:

Raises:

  • (ArgumentError) —

    if the URI is invalid

RDF::URI('http://t.co/') == 'http://t.co/'              #=> true

#join(*uris) ⇒ RDF::URI

Joins several URIs together.

This method conforms to join normalization semantics as per RFC3986, section 5.2. This method normalizes URIs, removes some duplicate path information, such as double slashes, and other behavior specified in the RFC.

Other URI building methods are ‘#/` and `#+`.

For an up-to-date list of edge case behavior, see the shared examples for RDF::URI in the rdf-spec project.

Examples:

Joining two URIs

RDF::URI.new('http://example.org/foo/bar').join('/foo')
#=> RDF::URI('http://example.org/foo')

Parameters:

Returns:

#query_values=(value) ⇒ Object

Sets the query component for this URI from a Hash object. An empty Hash or Array will result in an empty query string.

Examples:

Hash with single and array values

uri.query_values = {a: "a", b: ["c", "d", "e"]}
uri.query
# => "a=a&b=c&b=d&b=e"

Array with Array values including repeated variables

uri.query_values = [['a', 'a'], ['b', 'c'], ['b', 'd'], ['b', 'e']]
uri.query
# => "a=a&b=c&b=d&b=e"

Array with Array values including multiple elements

uri.query_values = [['a', 'a'], ['b', ['c', 'd', 'e']]]
uri.query
# => "a=a&b=c&b=d&b=e"

Array with Array values having only one entry

uri.query_values = [['flag'], ['key', 'value']]
uri.query
