-#  PERNOD RICARD DATA META MODEL - T-Box v1.1
+#  PERNOD RICARD DATA META MODEL - T-Box v1.2
 #  Owner: Bastien Gourdon - Data Governance Office
 #
-#  WHAT CHANGED vs v1.0
+#  WHAT CHANGED vs v1.1
 #  --------------------
+#  A. physicalizedIn -> storedIn. "Physicalized in" is jargon; the relation
+#     says where the data sits, and "stored in" says that to anyone.
+#
+#  B. hasSource MEANS ONE THING: the system that holds the authoritative data.
+#     It was drifting into a third meaning on Business Concepts and Metrics,
+#     where it named the DOCUMENT a record came from ("SODH back-doc v0.7").
+#     A business concept has no data source -- it has an owning domain, which
+#     is its authority, and a definition published in the glossary. The
+#     property is now forbidden on concepts by SHACL.
+#
+#  C. FIVE TERMS REMOVED OR DEPRECATED, none of them instantiated anywhere:
+#       Table                 deleted -- deprecated since v1.0, replaced by
+#                             BaseTable, and never used. A deprecation that
+#                             never ends stops meaning anything.
+#       constrainsRelation    derivable: constrainsField -> livesIn gives the
+#                             relation. An asserted edge redundant with an
+#                             existing path is a future divergence.
+#       MaterializedView      a class standing in for an attribute; being
+#                             derived is what dependsOn already says.
+#       approximateRowCount   volumetry with no identified use. queryCount30d
+#                             and lastQueriedOn carry the rationalisation case.
+#       hasVendor             marginal.
+#
+#  D. hasProductOwner drops from BLOCKING to a warning in the shapes. The SODH
+#     product owner is genuinely not appointed yet, and a blocking rule that
+#     cannot be satisfied truthfully forces invention -- the BR-004 lesson.
+#
+#  Environment and deployedIn stay, unused. Without them a DEV table and its
+#  PROD twin are indistinguishable and lineage pollutes silently on the first
+#  multi-environment harvest. Unused because nothing is harvested yet, not
+#  because they are useless.
+#
+#  WHAT CHANGED vs v1.0 (kept for reference)
+#  -----------------------------------------
 #  A. RELATIONS SIMPLIFIED AND GIVEN HONEST NAMES
 #     belongsToDomain + belongsToSubDomain  -> belongsTo (one property,
 #         scoped per class by SHACL; reusable if a domain family appears).

+SODH - data fixes v1.2
+=======================
+Four corrections found while reviewing the viewer.

+
+1. DATA DOMAIN OWNERS
+   Six named owners added, plus the hasDomainOwner link. Ownership was
+   readable only through the DGL until now, which conflates two roles: the
+   owner is accountable for the domain, the DGL runs its governance.
+
+2. hasSource CARRIED TWO MEANINGS
+   On a Data Element it named the system of origin (MDM Product, Group
+   Finance). On a Data Object it named the physical location (SODH Gold /
+   F_SELL_OUT). Same property, two concepts -- the defect we removed from
+   composedOf, still present one layer down. Split: physicalName holds the
+   relation name, hasSource holds the system. This is also what makes the
+   physical layer derivable: F_SELL_OUT plus 132 column names.
+
+3. METRIC UNITS ARE PLURAL
+   Five mother metrics compute elements in several units (9L and L, EUR and
+   LC and USD). A metric states every unit its variants are expressed in; a
+   Data Element states exactly one. Recomputed from the elements rather than
+   asserted, so the two can never drift.
+
+4. Sell Out Distribution -> Retail Distribution, matching the concept: sell
+   out counts units sold, distribution measures presence in store.

+WHAT IT DOES
+    1. physicalizedIn -> storedIn everywhere (no instances yet, done for
+       completeness so the term never appears again).
+    2. hasSource removed from every Business Concept. A concept has no source
+       of truth: its authority is its owning domain, its definition belongs in
+       the glossary. Asking which system defines it has no answer, because
+       every system that uses it would be a candidate.
+    3. hasSource on Metrics recomputed from the elements that implement them.
+       It said "SODH back-doc v0.7" -- the provenance of the record, not the
+       source of the data. Asserted rather than derived, by exception, because
+       "where can I get this metric" is a first-order question and the
+       derivation chain will have gaps until harvesting; a shape then checks
+       the assertion against the elements.
+    4. The SODH Data Product, its contract and its two interfaces.
+
+WHY THE PRODUCT OWNER IS EMPTY
+    Nobody is appointed. The field stays absent and the shape reports a
+    warning rather than a violation. Inventing a name to satisfy a blocking
+    rule is exactly how BR-004 produced padding in v0.6.
