reporting_period

[jfraschilla]

For the recent 10-Q filing for ticker COST, an example of a duration type from xbrl.reporting_periods is:

{'type': 'duration',
  'start_date': '2025-02-17',
  'end_date': '2025-05-11',
  'start_obj': datetime.date(2025, 2, 17),
  'end_obj': datetime.date(2025, 5, 11),
  'days': 83,
  'period_type': 'Period',
  'label': 'Period: February 17, 2025 to May 11, 2025',
  'context_ids': ['c-3','c-7','c-11','c-21','c-22','c-23','c-24','c-100','c-101','c-102','c-116','c-120','c-124','c-128'],
  'key': 'duration_2025-02-17_2025-05-11'
}

Notice that the period_type is 'Period'. Five of the entries with Type equal to duration have a period_type of 'Period' and one entry has a period_type of 'Annual'

If I look at the reporting_periods of 'Type'=='duration' for AAPL I get 'Quarterly', 'Semi-Annual', or 'Annual' which is what I am expecting to see for COST.

Is this a parsing issue?
