Overview

Root container for a harmonized model. Source adapters build one of these; consumer adapters read from it.

Element identity is global within the document: every package, classifier, relationship, diagram, and diagram element has a unique id. References between elements are by id, so the document can be sharded cheaply (no need to walk a tree to resolve a reference).

def classifiers_in_package(package_id)
  classifiers.select { |c| c.package_id == package_id }
end

#index_by_id ⇒ Object

Flat lookup indexes, built lazily by consumers. Not serialized — they're derived from the element collections.
