tbox: v1.2 - physicalizedIn devient storedIn, hasSource ramene a un seul sens (systeme detenant la donnee faisant autorite) et interdit sur les Business Concepts. Table supprime, MaterializedView / constrainsRelation / approximateRowCount / hasVendor deprecies. shapes: controle que la source d'une metrique correspond a celle de ses elements, unite multiple sur Metric et unique sur DataElement, hasProductOwner en avertissement. instances: Data Product SODH avec contrat et deux interfaces, 6 proprietaires de domaine nommes, Sell Out Distribution devient Retail Distribution. generated: les deux viewers partagent desormais le meme moteur

# 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).

ONE MEANING ONLY. It had drifted into naming the document a record came from ("SODH back-doc v0.7"), and into packing a system and a relation into one string ("SODH Gold / F_SELL_OUT"). The relation belongs in physicalName; the document belongs nowhere -- provenance of a record is not a property of the thing it describes.
MUST NOT appear on a Business Concept: a concept has no data source. Its authority is its owning domain and its definition is published in the glossary. Enforced by SHACL.
On a Metric it is asserted rather than derived, by exception, because "where can I get this metric" is a first-order question and the derivation chain (computedBy, then the data object holding the element) will have gaps before harvesting. A shape checks the assertion against the elements.""" .
