Overview

Generic, reflection-driven builder DSL: node methods are generated from each model's lutaml-model attribute metadata, so every current and future Newsmlg2 model is buildable without per-class builder code.

doc = Newsmlg2.build_news_item(guid: "...", lang: "en-GB") do |item|
item.item_meta do |meta|
  meta.item_class qcode: "ninat:text"
  meta.provider qcode: "nprov:acme" do |p|
    p.name "Acme News Agency"
  end
  meta.version_created "2026-08-30T12:00:00+00:00"
end
item.content_meta do |cm|
  cm.urgency 2
  cm.headline "Volcano erupts"
  cm.subject qcode: "medtop:20000962" do |s|
    s.name "Volcano"
  end
end
end
