What it claims
Version 2 of the External Perspective pack (CLM_Taxonomy_Domains_Regulatory_View_v2.pptx + .md, in 03 Credit Lifecycle/Industry Business Glossary/) adds Slide 3, answering two questions. (1) JBRC impact on a Credit Lifecycle Business Glossary: adopt the JBRC’s vocabulary — of its 37 published integrated-reporting terms only 3 match the 440-term Second Perspective glossary exactly (Data Dictionary, Taxonomy, Business Rule; all Core, Data Governance & Controls); 6 adjacent terms should be aligned to JBRC wording (Data Quality Rule, Data Lineage, Master Data, Reference Data, Calculation Logic, Business Glossary); ≈34 absent JBRC terms form an extension candidate set for Data Governance & Controls; NACE Code and Sector Classification terms must cite Rev. 2.1 (mandatory 1 Jan 2026); position the glossary as the bank-side semantic layer ready to map to BIRD/IReF and the coming common data dictionary (expert group H2 2026). (2) Indicative CDE view for a leading Irish retail bank (AIB/BOI), by the 14 taxonomy domains: total ≈100–190 CDEs, predominantly a subset of the 189 Core-tier terms; per-domain ranges anchored to Core counts (lower ≈ half Core, upper ≈ full Core, bands of 5), with flagged judgment adjustments — Risk Rating, Capital & Models raised (risk parameters near-all critical), Party & Customer raised (identifier-heavy; AnaCredit’s 89 attributes + 6 identifiers are the only identified additions beyond the 440 terms), Data Governance & Controls near-zero (governance artefacts, not data elements). External anchors: practitioner benchmark of ~10–15% of attributes per domain entering the CDE inventory (Finalyse); APRA’s 100-CRDE whole-bank pilot (2019). All figures flagged indicative; no supervisor prescribes a CDE count.
Notable quotes
- “CDEs are predominantly a subset of the existing glossary’s Core tier; the only identified additions are attribute-level counterparty/instrument identifiers.” (basis note)
What’s speculative vs. asserted
Asserted: the JBRC term-match results (programmatic exact-match against the workbook) and the JBRC document facts. Speculative/indicative: all CDE ranges and the ≈100–190 total [speculative — S-2026-08-21-paul-jbrc-cde-pack]; the 10–15% benchmark is practitioner-informed, not regulator-prescribed.
Topics this feeds
- CLM Data Taxonomy Governance — third slide of the External Perspective pack; extends the 13-Aug v1.
Open questions raised
- Whether the client adopts the ≈100–190 CDE range and the Core-tier-subset framing for scoping.
- Whether the ≈34 absent JBRC terms are added to the glossary’s Data Governance & Controls domain (extension) or held as a mapping reference only.
