In response, we have:

1. Archived predecessors (currency reference year 2010, 1975Q1 to 2019Q1) by renaming with an "_10" archive specifier, by marking metadata as discontinued, and by segregating in the catalog.
2. Created one-for-one replacements (currency reference year 2015) with an unchanged start date.
3. Recreated Moody's Analytics supplements as necessary.

Dataset properties:

• Framework: UN SNA 2008
• Industry classification: SSIC 2015
• Measurements: Millions of Singapore dollars at current prices (Mil. SGD) or chained year-2015 prices (Mil. Ch. 2015 SGDP)
• Adjustments: Seasonally adjusted (SA) or not (NSA)
• Native frequency: Quarterly
• Start date: Uniformly 1975Q1

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

• NACEEX_10AQ.ISGP = [DISCONTINUED] National accounts: Expenditure approach - Exports of goods and services, (Mil. 2010 SGD, SA)
• NAHECIAQ.ISGP    = Expenditure approach - Changes in inventories, (Mil. Ch. 2015 SGD, SA)
• NALSTOPAQ.ISGP   = Production approach - Taxes on products, (Mil. SGD, SA)

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

In addition, we corrected the mnemonic of one Moody's Analytics supplement, viz., constant-price statistical discrepancy.

• NAHESDAQ.ISGP » NALESD_10AQ.ISGP

Please be aware that

The corresponding annual series start at 1960.
