XML Schema

XmlSchema gem is a simple convertor utility for XML Schema (literal) datatypes to/from native Ruby objects.

Usage

$ require "xml_schema"

$ XmlSchema.datatype_of(true)  # => #<URI::HTTP:0x00000000dcff78 URL:http://www.w3.org/2001/XMLSchema#boolean>
$ XmlSchema.datatype_of(Time.now)  # => #<URI::HTTP:0x00000000dcff78 URL:http://www.w3.org/2001/XMLSchema#time>

$ XmlSchema.instantiate("55^^<http://www.w3.org/2001/XMLSchema#int>")  # => 55

XmlSchema also provides means to access and work with frequently used namespaces:

$ NS::OWL.uri  # => #<URI::HTTP:0x00000000dcff78 URL:http://www.w3.org/2002/07/owl>
$ NS::RDFS["hello"]  # => #<URI::HTTP:0x00000000dcff78 URL:http://www.w3.org/2000/01/rdf-schema#hello>

That's pretty much all there is to it.

Extras

This gem introduces LocalizedString to handle localized string literals.

$ s = LocalizedString.new("hello", :en)
$ s.lang  # => :en
$ XMLSchema.instantiate("hello@en")  # => <LocalizedString: "hello">

When compared to a String object, language is ignored and only the string content is compared. When compared to another LocalizedString, languages are also compared.

You can also initialize a LocalizedString as follows:

$ "bonjour".with_lang(:fr)  # => "bonjour"
