Curriculum

Schema last updated September 23, 2025.

About

Our Curriculum datasets align to Learning Commons’ K-12 curriculum ontology. You can query Knowledge Graph for curriculum data in a standardized way, without losing the distinctiveness of the original instructional design.


Content elements	Instructional materials that teachers and students engage with The instructional content preserves the original curriculum’s hierarchy and sequencing.
Metadata	Contextual information that supports instructional decisions, sequencing, and coherence Metadata is inferred from the content and makes instructional dependencies explicit. Use metadata to analyze how concepts build over time.

Key characteristics


Interoperability	Different curricula datasets can integrate seamlessly with other learning platforms and datasets.
Scalability	Additional curricula in the future will follow the same structure, ensuring coherence across instructional materials.
AI-enhanced instruction	Developers can query the data in a structured way, allowing AI-driven tools to provide more context-aware and pedagogically sound recommendations.

Data relationship diagram

Data model diagram: Curriculum entities (Course, LessonGrouping,
Lesson, Activity, Assessment, Material) and relationships
(hasEducationalAlignment, usesRoutine, hasDependency, and
references)

Diagram description

Example:

Course is the root (e.g., Illustrative Mathematics Grade 2)
LessonGrouping is a unit or module (e.g. Unit 3: Adding and Subtracting within 100)
- LessonGrouping -> hasEducationalAlignment -> StandardsFrameworkItem (e.g., 2.NBT.B.5)
- LessonGrouping -> hasPart -> Lesson OR Material
- LessonGrouping -> references -> GlossaryTerm
Lesson is a single session (e.g., Lesson 1: How do we count collections?)
- Lesson -> hasEducationalAlignment -> StandardsFrameworkItem
- Lesson -> hasPart -> Activity OR Assessment
- Lesson -> references -> GlossaryTerm
- Activity -> usesRoutine -> InstructionalRoutine (e.g., Number Talks)
- Assessment -> mutuallyExclusiveWith -> Assessment (equal alternatives)

See Entities for all possible nodes and Relationships for all possible edges.
