:hospitalOS a owl:Ontology ;

    schema:description "Models the ten operating-model concept categories (Clinical Pathways, Terminology & Ontologies, Workflows/Processes, Knowledge Graph, Tasks & Workforce, Master Data, Policies & Governance, Decision Rights, Logistics & Resources, Performance & Quality) and the relations that answer: what is done, by whom, with what, in what sequence, and under what rules. The source framing states this layer spans roughly 30,000-60,000 tasks and thousands of concepts hospital-wide; entities.ttl instantiates one representative pathway at illustrative scale, not the full inventory. Workflow/sequencing terms (ClinicalPathway, WorkflowStep, hasStep, nextStep) are cross-referenced via owl:equivalentClass/owl:inverseOf to the P-Plan ontology (http://purl.org/net/p-plan#) for interoperability with plan/step-modeling tools outside this corpus."@en ;
