def of_type(type_name)
  where(type: type_name)
end

#with_identifier(value) ⇒ Object

Exact match on the full identifier (use for any class of identifiers) ‘value’ is the cached value with includes the namespace (see spec) example Serial.with_identifier(‘MX serial ID 8740’)

def with_identifier(value)
  value = [value] if value.class == String
  t = Identifier.arel_table
  a = t[:cached].in(value)
  self.joins(:identifiers).where(a.to_sql).references(:identifiers)
end

#with_identifier_type_and_namespace_method(identifier_type, namespace_id, sorted = nil) ⇒ Object

!! Note that adding a sort also adds a where clause that constrains results to those that have numeric identifier.identifier
