Overview

Knowledge Graph entities connect through relationships. Thematically connected entities and relationships are grouped into categories like Standards and Learning components.

Entities by dataset category

Dataset category	Entities
Standards	`StandardsFramework`, `StandardsFrameworkItem`
Learning components	`LearningComponent`
Curriculum	`Course`, `LessonGrouping`, `Lesson`, `Activity`, `Assessment`, `Material`, `ClassroomMaterial`, `GlossaryTerm`, `InstructionalRoutine`
Instructional practices	`LearnerModel`, `Factor`, `Strategy`

All relationships share a common property set.

Dataset category	Relationships
Standards	`hasChild`, `supports`, `hasEducationalAlignment`, `hasStandardAlignment`
Learning components	`supports`
Learning progressions	`buildsTowards`, `relatesTo`
Curriculum	`hasPart`, `hasEducationalAlignment`, `usesRoutine`, `uses`, `hasDependency`, `hasReference`, `references`, `mutuallyExclusiveWith`
Instructional practices	`hasFactor`, `hasStrategy`, `interactsWithFactor`, `targetsFactor`, `relevantToStandard`

Controlled vocabularies used across the Knowledge Graph are documented in Enums and formats.
