On 11 May, the source wrote (citation):

The Industrial Production & Turnover indices have been compiled with reference to base year 2015=100. The new series has been calculated using updated weights from the Census of Industrial Production 2015 and the rebased Wholesale Price Index 2015 = 100.

The corpus of series in this vintage has been reduced by the source. In the data table, the three NACE activity aggregates [10, 11], [20, 21] and [26, 27] are now marked as follows (citation):

.. indicates that the observation is missing or fall under the limit of discretion/uncertainty.

In response, we have:

1. Archived the predecessors (2010=100, January 2010 to February 2018) by renaming with an "_10" specifier, by marking metadata as "discontinued," and by segregating in the catalog.
2. Created replacements (2015=100) as possible; some categories have been terminated by the source. They start January 2015, there are two analytic variants (seasonally adjusted (SA) or not (NSA)), and the classification is NACE Rev. 2.
3. Assigned standardized mnemonics to the replacements.

The active IPI series reside in the historical catalog (Ireland » Industry » Industrial production index » 2015=100) and the predecessors under the associated "discontinued" node. They include, for example:

• SBJIPMMEG_10AM.IIRL = [DISCONTINUED] Industrial Production Index: Industries [05 to 35], (Vol.Index 2010=100, SA)
• IPJ105UM.IIRL       = Dairy products [105], (Vol. Index 2015=100, NSA)
• IPJ27AM.IIRL        = Electrical equipment [27], (Vol. Index 2015=100, SA)

And under (Ireland » Industry » Industrial turnover index » 2015=100):

• SBITN10UM.IIRL      = [DISCONTINUED] Industrial Turnover Index: Food products [10], (Index 2010=100, NSA)
• TNJMFPAM.IIRL       = Paper and paper products; printing and reproduction of recorded media [17; 18], (Index 2015=100, 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.

Please be aware that

By definition, industrial production is a volume index, i.e., adjusted to remove the effect of price changes.
