In response, we have:

• Archived the chained-price predecessors (Mil Ch. 2015 EUR) by renaming with an "_15" specifier, by marking the metadata as "discontinued", and by segregating in the catalog.
• Created replacements (Mil Ch. 2016 EUR), which have an unchanged start date. Properties are otherwise unchanged.
• We have also archived and replaced the corresponding current-price series, thereby enabling comparison of any other revisions (aside from the change in reference year) that may have been performed.

The active series reside in the historical catalog (Ireland » National Accounts » by Expenditure | by Value Add » Quarterly) and the predecessors under the associated "discontinued" node. They include, for example:

• NACSGVAT_15UQ.IIRL = [DISCONTINUED] National accounts: Production approach - Gross value added - All sectors, (Mil. Ch. 2015 EUR, NSA)
• NACSGVATUQ.IIRL    = Production approach - Gross value added - All sectors, (Mil. Ch. 2016 EUR, NSA)
• NACECGG_15UQ.IIRL  = [DISCONTINUED] By Expenditure - Net Expenditure by Central and Local Govt. on Current Goods and Services, (Mil. Ch. 2015 EUR, NSA)
• NACECGGUQ.IIRL     = By Expenditure - Net Expenditure by Central and Local Govt. on Current Goods and Services, (Mil. Ch. 2016 EUR, NSA)
• NALECI_15AQ.IIRL   = [DISCONTINUED] By Expenditure - Value of Physical Changes in Stocks, (Mil. EUR, SA)
• NALECIAQ.IIRL      = By Expenditure - Value of Physical Changes in Stocks, (Mil. EUR, SA)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" that accepts a mnemonic.
