--== 1. Overall analysis & review of the data model ==
--
--=== 1.1 Strengths of the current design ===
--
--* (((
--**Identity vs. version pattern**
--Using base entities plus version entities (CLAIM + CLAIM_VERSION, SCENARIO + SCENARIO_VERSION, etc.) is exactly how modern knowledge systems handle:
--
--* auditability
--* time evolution
--* re-evaluation triggers
--* federation and partial replication
--)))
--* (((
--**Scenario-centric reasoning**
--Separating //Claim// (what people argue about) from //Scenario// (interpretive frame) is very aligned with “truth landscape” style systems:
--
--* Scenarios explain //why people disagree//.
--* Verdicts are tied to specific scenario versions → avoids mixing incompatible assumptions.
--)))
--* **Evidence and verdicts as first-class entities**
--Evidence is explicit, linked to scenarios, and verdicts are per scenario. This matches good practice from fact-checking, scientific assessment panels, and trust graphs.
--* (((
--**Cluster level (CLAIM_CLUSTER)**
--Grouping related claims avoids duplication and lets you:
--
--* reuse scenarios across paraphrases
--* share embeddings / semantic search
--* keep the system scalable as the corpus grows.
--)))
--* (((
--**Explicit review layer (REVIEW_ACTION, roles, etc.)**
--Separating “data” from “who reviewed what” keeps the model clean, and is exactly what you want for:
--
--* governance
--* permissions
--* audit trails
--* future trust scoring per user / role.
--)))
--
------
--
--=== 1.2 Design decisions I’m locking in (based on our discussions) ===
--
--To make the model consistent and “state-of-the-art”, I will assume the following as //current intended design//:
--
--1. (((
--**Claims vs Scenarios**
--
--* CLAIM is the stable identity for “what people argue about”.
--* CLAIM_VERSION are individual phrasings / formulations / metadata.
--* (((
--SCENARIO belongs to a **CLAIM**, not to a specific CLAIM_VERSION.
--Rationale:
--
--* Many different phrasings share the //same// scenario.
--* You avoid duplicating scenarios per wording.
--)))
--* SCENARIO_VERSION holds detailed definitions, assumptions, boundaries, etc.
--)))
--1. (((
--**Version-specific reasoning**
--
--* **Verdicts** are always attached to SCENARIO_VERSION (not base SCENARIO).
--* **Evidence links** are between SCENARIO_VERSION and EVIDENCE_VERSION.
--→ This is what we agreed when we said //“SCENARIO_EVIDENCE_LINK should link the respective versions instead”//.
--)))
--1. (((
--**Clusters**
--
--* CLAIM_CLUSTER groups Claims (semantically close claims).
--* It is visible in **both diagrams** (Core Data Model and Data Use).
--)))
--1. (((
--**Review vs data**
--
--* (((
--All review happens **on versioned entities**:
--
--* CLAIM_VERSION
--* SCENARIO_VERSION
--* EVIDENCE_VERSION
--* SCENARIO_EVIDENCE_LINK_VERSION
--* VERDICT_VERSION
--)))
--* REVIEW_ACTION is the generic log of //who// did //what// on //which version//.
--)))
--1. (((
--**Users & roles**
--
--* USER has an attribute (or a linked entity) that distinguishes **technical users** from normal accounts.
--* We //keep// TECHNICAL_USER as a specialisation of USER (strictly technical accounts).
--* All human & technical accounts can hold roles via USER_ROLE_MEMBERSHIP.
--* (((
--Roles include:
--
--* READER
--* CONTRIBUTOR
--* TRUSTED_CONTRIBUTOR
--* REVIEWER
--* MODERATOR
--* SYSTEM_ADMIN / MAINTAINER
--* FEDERATION_OPERATOR
--* FEDERATION_ADMIN
--(all present in the Data Use ERD, but as rows of ROLE rather than separate entities).
--)))
--)))
--
------
--
--=== 1.3 Gaps / potential problems ===
--
--These are the main issues & missing areas I see:
--
--1. (((
--**Versioning text in chapter 5 is currently too thin (‘…’ placeholders)**
--
--* (((
--The spec does not yet //verbally// spell out:
--
--* the identity vs version pattern, systematically
--* how re-evaluation triggers are derived from version changes
--* how this aligns with federation (which versions are replicated where).
--)))
--)))
--1. (((
--**No explicit “provenance granularity” in the model**
--
--* (((
--EVIDENCE is a single entity. For more advanced use cases, you may later want:
--
--* EVIDENCE_SOURCE (the whole article/report/video)
--* EVIDENCE_FRAGMENT (specific paragraph/clip with its own reliability, quote, etc.)
--)))
--* For now, I’ll keep EVIDENCE/EVIDENCE_VERSION as is, but I’ll mention this as a possible extension.
--)))
--1. (((
--**Review target polymorphism**
--
--* (((
--REVIEW_ACTION can apply to multiple entity types. In the diagram this shows as multiple relationships:
--
--* CLAIM_VERSION → REVIEW_ACTION
--* SCENARIO_VERSION → REVIEW_ACTION
--* etc.
--)))
--* A more “pure” relational modeling would use a generic “subjectType + subjectId” or an intermediate “REVIEW_TARGET” table.
--* For readability, I’ll keep the simpler multi-edge representation and mention the polymorphism in text.
--)))
--1. (((
--**Federation details missing from core ERD**
--
--* There is no explicit FEDERATION_NODE / REPLICATION_LOG in the Data Model chapter.
--* This is ok for “core logical data model”, but I’ll add a short note that federation metadata is handled in the Federation chapter and via additional entities.
--)))
--1. (((
--**Automation / AKEL artifacts left implicit**
--
--* (((
--The Data Model chapter currently doesn’t describe:
--
--* AKEL task queues
--* extraction runs
--* model versions
--)))
--* That’s fine for now; I’ll just clarify that those belong to a “Processing / AKEL” submodel, not the core logical data model.
