Motivation

Wikipedia and Wikidata have only very basic information on military ordnance (missiles, bombs, rockets, small arms munitions, tank and artillery rounds, etc) even though publications such as the Yellow Book and public NSN part information provides detail on exact variants of ordnance. For example, Wikipedia may have a page on a "Mk 82 bomb" but this is a highly conflated item which may include different variants of a bomb casing (with varying amounts of explosive) and with different guidance systems attached. Applying a DODIC code allows these variants to be listed out as separate Wikidata items, avoiding conflation of topics. --Dhx1 (talk) 06:29, 2 October 2024 (UTC)[reply]

Discussion

@Dhx1: your examples should have Wikidata items on the left, not string values, can you fix? ArthurPSmith (talk) 23:03, 3 October 2024 (UTC)[reply]
Examples changed to include existing items. --Dhx1 (talk) 02:23, 4 October 2024 (UTC)[reply]
ArthurPSmith, would you like to give your opinion? Regards, ZI Jony ^(Talk) 08:42, 10 October 2024 (UTC)[reply]
@Dhx1: Hmm, so you just added these items as examples? Do we actually have any existing items to which this identifier would apply? If not I don't see it as being very useful. ArthurPSmith (talk) 20:40, 14 October 2024 (UTC)[reply]
Wikidata currently only knows a few items (other than many I have added to date) for variants of US ordnance. However, English Wikipedia (others too) have extensively listed and provided some documentation of the often significant differences in variants, for example https://en.wikipedia.org/wiki/Tomahawk_(missile_family)#Variants has a list of variants most of which I have added Wikidata items for. The variants are also something which Wikimedia Commons cares about, for example, https://commons.wikimedia.org/wiki/Category:BGM-109_Tomahawk_Block_IV and https://commons.wikimedia.org/wiki/Category:BGM-109G_Gryphon versus https://commons.wikimedia.org/wiki/Category:BGM-109_Tomahawk or also https://commons.wikimedia.org/wiki/Category:AMRAAM-ER and https://commons.wikimedia.org/wiki/Category:CATM-120C and https://commons.wikimedia.org/wiki/Category:SLAMRAAM versus https://commons.wikimedia.org/wiki/Category:AIM-120_AMRAAM Dhx1 (talk) 21:59, 15 October 2024 (UTC)[reply]
Support OK, I guess the specific details are important for identification. I hope new items created based on this will be well structured and linked to their related items. ArthurPSmith (talk) 17:29, 18 October 2024 (UTC)[reply]

Comment If this is limited to ordnance, shouldn't ordnance be in the name of the property? AdamSeattle (talk) 04:04, 26 October 2024 (UTC)[reply]
Comment "DODIC" is the official name of the identifier that people interested in this property would search for. It is unhelpfully non-descriptive as many military acronyms are. Rather than the name being clear in purpose, the description of the property (which Wikidata controls) makes clear what this identifier achieves. Dhx1 (talk) 22:49, 28 October 2024 (UTC)[reply]
Comment Is the source pdf a complete list, if not how will other values be found? How many values are expected in total?
Comment It's an ever expanding list. There is a database YellowBook.sqlite as part of a now-defunct Android app YellowBook v2.1.0 (APK still available online on non-official app stores) which lists 5288 DODIC codes per query "SELECT COUNT(*) FROM (SELECT DODIC FROM MunitionsHazardClass GROUP BY DODIC);". Future changes would have to be obtained through means such as being mentioned in official budget papers for Army, Air Force, Navy, Marines, etc for the type of ordnance budgeted to be procured, or a new app or new PDF publication. --Dhx1 (talk) 22:46, 28 October 2024 (UTC)[reply]

Support proposer has a good plan. Vicarage (talk) 03:45, 29 October 2024 (UTC)[reply]
