You can use it to retrieve metadata of Calconnect Standards from https://standards.calconnect.org, and access such metadata through the CcBibliographicItem object.

Add this line to your application’s Gemfile:

gem 'relaton-un'

And then execute:

$ bundle

Or install it yourself as:

$ gem install relaton-un

Usage

Configuration

Configuration is optional. The available option is logger which is a Logger instance. By default, the logger is Logger.new($stderr) with Logger::WARN level. To change the logger level, use RelatonUn.configure block.

require 'relaton_un'
=> true

RelatonUn.configure do |config|
  config.logger.level = Logger::DEBUG
end

Search for a standard using keywords

hits = RelatonUn::UnBibliography.search("TRADE/CEFACT/2004/32")
=> <RelatonUn::HitCollection:0x007fc4e6ec2018 @ref=TRADE/CEFACT/2004/32 @fetched=false>

item = hits[0].fetch
=> #<RelatonUn::UnBibliographicItem:0x007fc4e6ac3138
...

XML serialization

item.to_xml
=> "<bibitem id="TRADE-CEFACT-2004-32" type="standard" schema-version="v1.2.1">
      <fetched>2022-12-05</fetched>
      ...
    </bibitem>"

With argument bibdata: true it outputs XML wrapped by bibdata element and adds flavor ext element.

item.to_xml bibdata: true
=> "<bibdata type="standard" schema-version="v1.2.1">
      <fetched>2022-12-05</fetched>
      ...
