In response, we have:

1. Archived the predecessor indexes (2008=100, 1990Q1 to 2019Q1) by renaming with an "_08" specifier, marking metadata as "discontinued", and segregating in the catalog.
2. Created as-reported replacements (2015=100), which have standardized mnemonics.
3. Transplanted the global concept alias PPI.IHKG.

Active subset properties:

• Classification: Aggregates over HSIC V2.0
• Measurement: Fixed-base index relative to 2015 (Index 2015=100)
• Adjustments: 
• Not seasonally adjusted (NSA)
• Seasonally adjusted (SA)

The series reside in the historical catalog (Hong Kong » Prices » Producer Price Index » Base 2015).
