improve MIC-wikidata alignment

[VladimirAlexiev]

I added MIC to Wikidata. Last update was maybe 1y ago. Spent a lot of time on matching existing exchanges. I think most items are ok, but I'm sure there are omissions and merges that still need to be done.

• Do you get your alignments skos:closeMatch wd:Qnnn directly from WD?
• Would you like to help with improving the situation in WD?
• Below is some info on ambiguous/duplicate codes, but I have a lot more files locally.
  • In particular, we need to check which current MIC codes are still missing from WD. A year ago they were COTC|ECHO|JSES|JSJX|LMEC|MIBG|NMRA|OTCN|TPSL|TSGI|XSWB|XZAP

Thanks, for the overview. I added some of the obvious ones, XVSE (Q7914256), XBSE (Q1003245), XLUS (Q111263892). But stopped there because items appear to need merging or scope clarification.

Lusaka Stock is now Lusaka Securities, for the same reason you cannot find the Zambian Commodity Exchange (ZAMACE), it got merged into LuSE, like years ago.

For XBSE there's Q93358786 as well as Q1003245. Here the question is how to proceed, BVB operates the spot market (equities, bonds) as well as a derivatives market (mic XBSD), so the uniqueness constraint makes no sense. I chose to put XBSE in Q1003245 because XBSE is also the operator of both segments.

I'm willing to help but there's not a lot of guidance on wd on how to reflect which resource covers what.

Oh, Oddo BHF is quite the same, they use ODDO for everything except OTC or RFQ trades, where they use ODOC.

[VladimirAlexiev]

• linked Zambian Commodity Exchange to Lusaka Stock Exchange
• merged Q93358786 to Q1003245 as "Stock exchange Bucharest, Romania and its main SPOT REGULATED MARKET"
• ODOC "ODDO CONTREPARTIE" should be split from ODDO "ODDO BHF", but I haven't done it.

@hroptatyr more important are the omissions. Total unique MICs in WD: https://w.wiki/5cRB : 1944. Total uses as main statement: https://www.wikidata.org/wiki/Property_talk:P7534 : 1948.

This should be compared to the total in the MIC distribution, which are:

• 2021-09: 2069
• 2021-11: 2469
• 2022-08: 2536

I've added these counts to https://www.wikidata.org/wiki/Property:P7534#P4876. So now https://www.wikidata.org/wiki/Property_talk:P7534 shows "1,948 out of 2,536 (77% complete)".

Would you like to help me match and import the new MIC records to WD, so we have 100% coverage again? I do this with OpenRefine. Actually I'll talk to some colleagues.

• data description: https://www.wikidata.org/wiki/Wikidata:Property_proposal/MIC
• Reconciliation sequence:
  • reconcile/add MIC_Market_Categories
  • reconcile col "MIC" by ID. For the ones not found:
  • reconcile by Name (maybe limiting to type "stock exchange" or "stock market".
  • For the ones found: make statements about "MIC code"
  • For the ones not found: (maybe I still have an OR project that does a lot of that)
  • reconcile country
  • reconcile city
  • assign a type: resolve MIC_MARKET_CAT to WD item, else if MIC=OPERATING then "stock exchange", else "stock market"
  • lowercase website
  • make WD create statements

[hroptatyr]

Oh certainly I would.
