currently we only have triplified NAICS 2022 codes. There are some slight differences between those and earlier years of naics.
Other code years are: 2017, 2012, 2007, 2002, 1997.
Source for 2022 triplification: https://www.census.gov/naics/ also has other years.
NAICS assoc, census and bls also have crosswalk files:
The ontology would keep single instances for those codes that are shared, and just add the fio:ofYear tag.
However it would not currently support changing definitions / descriptions that use the same code identifier, so if that is important we may need to extend to support that.
There are some instances from us frs facilities that use a naics code that is not instantiated in our 2022 data. Some of those may be earlier codes now deprecated, others maybe inaccuracies.
