**********************************************************
** An unknown rdf namespace has been found and a random
** alias has been generated for it : '#{_alias}'
**
** Using a random alias is OK if you do not need to
** reference a namespace somewhere in your code.
**
** If, for example, you need to declare methods
** for elements of this namespace
** (for generating code for example),
** you will need a fix namespace alias.
**
** Run the following ruby code once in your ruby
** program to declare a new alias:
**
** YourCode.rb
**   require 'ontomde-core'
**   (...)
**   UriNamespace.instance.addAlias('yourAlias',
**       '#{ns.gsub(/\//,'\\\/')}'
**       )
