In response, we have:

1. Archived the predecessors (2010=100, January 1962 to July 2018) by renaming with an "_10" specifier, marking the metadata as "discontinued", and segregating in the catalog.
2. Created one-for-one replacements (2015=100, from January 1962).
3. Assigned standard mnemonics to the replacements.
4. Refurbished the catalog.

Dataset properties:

• Measurement: Fixed-base index relative to 2015 (Index 2015=100)
• Adjustment: Not seasonally adjusted (NSA), or calendar day and seasonally adjusted (CDASA)
• Frequency: Monthly
• Start: As early as January 1962
• Subject to revisions: Yes
• Lag: Two months

The series reside in the historical catalog (Germany » Trade » Foreign Trade » Price index and unit value index) and include, for example:

• TRIVAEX_10CM.IDEU = [DISCONTINUED] Foreign Trade: Export price index, (Index 2010=100, CDASA)
• TRIEXCM.IDEU      = Foreign trade: Export price index, (Index 2015=100, CDASA)
• TRIIMUM.IDEU      = Foreign trade: Import price index, (Index 2015=100, NSA)
• TRITTCM.IDEU      = Foreign trade: Terms of trade, (Index 2015=100, CDASA)

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.
