SystemCodeDisplay (en)DefinitionJSONXML
http://smart.who.int/base/CodeSystem/KGL1Classes  publicationPublicationA WHO normative publication: a guideline, guidance, recommendation summary, or classification. Metadata follows Dublin Core, which HealthInterventions already uses.
http://smart.who.int/base/CodeSystem/KGL1Classes  publication-sectionPublication sectionA chapter, annex or numbered section. Recommendations are located by section and page, which is what makes an extraction checkable.
http://smart.who.int/base/CodeSystem/KGL1Classes  recommendationRecommendationThe atomic normative statement. This is the node nothing in the WHO estate currently makes addressable.
http://smart.who.int/base/CodeSystem/KGL1Classes  remarkRemarkAn implementation consideration attached to a recommendation. Grounded: the BCG table's first annotationEntry carries exactly this — "Neonates born to women of unknown HIV status should be vaccinated as the benefits…" — clinical nuance that shapes the decision logic but is not the recommendation itself.
http://smart.who.int/base/CodeSystem/KGL1Classes  evidenceEvidenceThe body of evidence behind a recommendation, with its GRADE certainty rating.
http://smart.who.int/base/CodeSystem/KGL1Classes  populationPopulationPICO P.
http://smart.who.int/base/CodeSystem/KGL1Classes  interventionInterventionPICO I. The clinical or public-health action, distinct from health-intervention, which is the DAK-facing component.
http://smart.who.int/base/CodeSystem/KGL1Classes  comparatorComparatorPICO C. Frequently absent in WHO recommendations; absence is recorded rather than invented.
http://smart.who.int/base/CodeSystem/KGL1Classes  outcomeOutcomePICO O.
http://smart.who.int/base/CodeSystem/KGL1Classes  health-interventionHealth interventionWhat a recommendation is about, and the hinge to L2. Corresponds to the DAK component smart-base defines as HealthInterventions — today `id`, `description[x]` and `reference 1..* DublinCore`, i.e. a bibliographic citation with no recommendation behind it. This class is what that citation should resolve to.
http://smart.who.int/base/CodeSystem/KGL1Classes  scheduleScheduleA normative delivery schedule. Grounded: the BCG table cites "WHO recommendations for routine immunization – summary tables", which IS a schedule publication — the single most-cited L1 source in the immunization DAK.
http://smart.who.int/base/CodeSystem/KGL1Classes  schedule-entrySchedule entryOne row of a schedule: which intervention, for whom, when, how many doses. This is the granularity a decision table actually consumes — the BCG rules turn on dose count, age and interval since a live vaccine.
http://smart.who.int/base/CodeSystem/KGL1Classes  indicatorIndicatorA programme indicator defined normatively at L1. Distinct from the DAK's ProgramIndicator component, which is its L2 expression; that model already carries `references 0..* id` pointing at health intervention ids.
http://smart.who.int/base/CodeSystem/KGL1Classes  terminology-codeTerminology codeA code in an external terminology — ICD-10, ICD-11, SNOMED CT, ATC, or a WHO classification such as CDHI. CROSS-REFERENCE ONLY. It records system, code and display, and asserts NOTHING about the terminology: no hierarchy, no subsumption, no synonyms, no post-coordination. The terminology has its own authority, its own release cycle and its own tooling, and a partial copy here would be wrong within one release. Resolve meaning against the terminology server, not against this graph.
http://smart.who.int/base/CodeSystem/KGL1Classes  citationCitationA citation string exactly as it appears in an L2 or L3 artefact, together with what it was resolved to. Grounded directly in the BCG table, where every rule's annotationEntry[1] reads "WHO recommendations for routine immunization – summary tables (March 2023) (1)" — a citation that no tool can currently follow. This class is where that string becomes a link, and where the fact that resolving it was a judgement gets recorded.
http://smart.who.int/base/CodeSystem/KGL1Classes  external-artifactExternal artefactAn L2 or L3 artefact addressed by canonical URL — a BPMN process, a DMN decision table, a FHIR PlanDefinition. Deliberately opaque: it carries an IRI and a free-text kind, and this graph asserts nothing about its internal structure. That opacity is the boundary. The L2 and L3 subgraphs model those artefacts properly; L1 only needs to point.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
