In response, we have archived the predecessors (2010=100, January 1975 to December 2017) by renaming with an "_10" specifier, by marking metadata as "discontinued", and by segregating in the catalog. The replacements (2015=100) have an unchanged start date. There are two presentations, seasonally adjusted (SA) or not (NSA). For each industry aggregate there are three indexes: production, shipment, and inventory.

The series reside in the historical catalog (South Korea » Industry » Industrial production index » ... » By production, shipment, inventory) and include, for example:

• IPIINMM_10AM.IKOR  = [DISCONTINUED] Inventory index: Mining and manufacturing, (Index 2010=100, SA)
• IPIINMMAM.IKOR     = Inventory index - Mining and manufacturing, (Index 2015=100, SA)
• IPIMFICT_10UM.IKOR = [DISCONTINUED] Production index - Information and communication technology manufacturing, (Index 2010=100, NSA)
• IPIMFICTUM.IKOR    = Production index - Information and communication technology manufacturing, (Index 2015=100, NSA)

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.

Please be aware that

The production index for mining (in NSA and SA terms) has been terminated by the source.

The "ICT manufacturing" aggregate is reported in NSA terms, but not SA.
