    rdfs:comment "Status is four independent questions wearing one word: what does the advertiser want, may the entity serve, why not, and does it still exist. One provider answers all four with a single twelve-value enumeration whose members mix an advertiser's intent with a policy verdict, an unpaid invoice, a paused ancestor, and a deleted record. Because the answers are collapsed, the most common operational question in advertising, why is this ad not running, cannot be asked at all. This module separates the four and reifies the reason, so a hold names its kind and the resource it originated from. That last part is what makes an inherited pause traceable to the ancestor responsible rather than leaving an operator to walk the hierarchy by hand." ;

# --- Delivery state ----------------------------------------------------------

:DeliveryState
    a rdfs:Class ;
    rdfs:subClassOf prov:Entity ;
    rdfs:label "delivery state" ;
    rdfs:comment "The delivery situation of one advertising entity: advertiser intent, reported holds and lifecycle standing, and optional legacy provider permission in its producer scope. Omitted permission remains unknown; these states do not establish measured impressions or complete cross-provider eligibility." ;
    dcterms:description "Reified so the four independent answers stay separate and can carry provenance. A state is an observation about an entity at a point in time, not a property of the entity, which is why it can disagree with a later one without contradiction." .

:DeliveryIntent
    a rdfs:Class ;
    rdfs:subClassOf skos:Concept ;
    rdfs:label "delivery intent" ;
    rdfs:comment "What the advertiser wants the entity to do: run, or not run. Intent is a setting, and it is independent of whether delivery actually occurs." ;
    dcterms:description "Deliberately narrow. Archival and deletion are not intents: they describe whether the entity still exists, and folding them in means a query for everything the advertiser switched off silently returns records that are gone." .

:ServingState
    a rdfs:Class ;
    rdfs:subClassOf skos:Concept ;
    rdfs:label "serving state" ;
    rdfs:comment "Whether the provider lets the entity serve, independent of what the advertiser intends. Whether impressions are delivered is measured by advertising-measurement, not stated by a serving state." ;
    dcterms:description "Intending to run and not serving is the normal case in advertising operations, not an anomaly. A model with one status field cannot express it, which is why an entity under review, out of budget, or beneath a paused ancestor all report as though the advertiser had switched them off." .

:ServingHold
    a rdfs:Class ;
    rdfs:label "serving hold" ;
    rdfs:comment "A reported constraint preventing or restricting delivery, naming its kind and the resource it originated from. A hold alone is not an observation of actual serving or non-serving." ;
    dcterms:description "Reified because the reason determines who can act. A policy rejection is the advertiser's to appeal, an unpaid invoice is the account owner's to settle, an exhausted budget is a configuration change, and a paused ancestor is somebody else's entity entirely. Providers expose these as untyped string arrays or fold them into a status enumeration, so none of that is decidable today." .

:HoldKind
    a rdfs:Class ;
    rdfs:subClassOf skos:Concept ;
    rdfs:label "hold kind" ;
    rdfs:comment "The category of a serving hold, such as a policy review outcome, a billing problem, an exhausted allowance, or an ancestor that is paused." ;
    dcterms:description "A concept class rather than a fixed enumeration, because providers surface hold reasons at different granularities and profiles need to extend the scheme without minting parallel classes." .

:LifecycleState
    a rdfs:Class ;
    rdfs:subClassOf skos:Concept ;
    rdfs:label "lifecycle state" ;
    rdfs:comment "Whether the entity is live, archived out of the working set, or deleted." ;
    dcterms:description "Separate from delivery intent because it answers a different question. An archived entity is not one the advertiser paused; it is one removed from view whose historical metrics remain valid and must still be readable." .

No value establishes measured delivery or aliases the independent neutral eligibility or provider serving-report axes." ;

    skos:definition "The entity is eligible to serve, while the provider reports that delivery is restricted to part of what is set up: some markets, placements, assets or settings.

    rdfs:comment "Delivery is prevented by the setup of the entity where the hold originates, which may be an ancestor of the held entity: a required setting, targeting or asset is missing or misconfigured, or the entities beneath it are missing or all switched off. The remedy is a change to that setup, which the advertiser makes." ;
    skos:definition "A hold arising from how the originating entity, or the entities beneath it, are set up, rather than from review, payment, a spent allowance, the schedule or an ancestor that cannot serve." .

    rdfs:label "unclassified" ;
    rdfs:comment "Delivery is prevented for a reason the provider does not name, or names in terms no other hold kind covers. Who can act is unknown until the provider's own reason is read.
