# Iroko Framework — PROV-O Alignment  v1.3.0
# ==========================================================================
# Namespace: https://ontology.irokosociety.org/iroko#
# Requires:  iroko-core v1.3.0
#            iroko-agency v1.3.0
#            iroko-authority v1.3.0
#
# Reference-only alignment to PROV-O (http://www.w3.org/ns/prov#).
#
# STRATEGY: Subclass alignment only.
# • No owl:equivalentClass
# • No owl:imports
# • No semantic collapse
#
# Subclassing means:
#   Iroko classes remain sovereign — they are specializations of PROV
#   classes, not replacements. A SPARQL query over prov:Agent will
#   find iroko sacred agents and authorities. A query over iroko
#   classes finds only iroko resources. Neither overwrites the other.
#
# This file should be loaded OPTIONALLY for interoperability contexts.
# It is not required for the core framework to function.

# ===========================================================================
# AGENTS
# Sacred agents and ritual authorities are specializations of prov:Agent.
# ===========================================================================

iroko:SacredAgent
    rdfs:subClassOf prov:Agent .

# iroko:Authority extends iroko:RitualAuthority which is the Core stub.
# We align the Core stub to prov:Agent — everything that subclasses it
# (iroko:Authority and any tradition-specific authority subclasses)
# inherits the alignment transitively.
iroko:RitualAuthority
    rdfs:subClassOf prov:Agent .


# ===========================================================================
# ACTIVITIES (events)
# Ritual events are specializations of prov:Activity.
# ===========================================================================

iroko:RitualEvent
    rdfs:subClassOf prov:Activity .

# FieldworkEvent in Core — fieldwork is a prov:Activity
iroko:FieldworkEvent
    rdfs:subClassOf prov:Activity .


# ===========================================================================
# ENTITIES (claims, policies, knowledge graphs)
# ===========================================================================

# Assertions are provenance entities — claims with tracked provenance
iroko:Assertion
    rdfs:subClassOf prov:Entity .

# AccessPolicy nodes are provenance entities — governed artifacts
iroko:AccessPolicy
    rdfs:subClassOf prov:Entity .

# LineageKnowledgeGraph is a named graph — a prov:Entity by definition
# (already declared in Core; alignment restated here for completeness)
iroko:LineageKnowledgeGraph
    rdfs:subClassOf prov:Entity .

# DocumentaryEvidence — archival records are prov:Entity
iroko:DocumentaryEvidence
