The Knowledge Graph includes the following `LearnerModel`s: * Math PK-2 * Math 3-6 * Math 7-10 * Literacy PK-3 * Literacy 4-6 * Literacy 7-12 * Portrait of a Learner PK-3 * Portrait of a Learner 4-8 * Portrait of a Learner 9-12 | Property | Description | Type | Cardinality | | :--------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :------------------------------------------------------------------------------------------------------- | :---------- | | `academicSubject` | Academic subject | [`AcademicSubjectENUM`](/knowledge-graph/graph-reference/value-and-format-standards#academicsubjectenum) | 1 | | `attributionStatement` | Textual credit that acknowledges the source or creator of a work, included when required by the content’s license (e.g., Creative Commons BY); the statement specifies how the creator should be attributed in accordance with the license terms. | `String` | 1 | | `author` | Author of content | `String` | 1 | | `content` | Materials that make up a learner model along with additional information (if available) | `String` | 0..1 | | `description` | Description of the item | `String` | 0..1 | | `gradeLevel` | Specifies the educational grade for which the curriculum component is intended | [`Array of GradeLevelENUM`](/knowledge-graph/graph-reference/value-and-format-standards#gradelevelenum) | 0..n | | `identifier` | Identifier of the item, either as textual strings or as URL (URI) links | `String` | 1 | | `license` | License document that applies to this content, typically indicated by URL | `String` | 1 | | `name` | Name of the item | `String` | 0..1 | | `provider` | Service provider, service operator, or service performer | `String` | 1 | ### `Factor` Characteristic that influences learning or performance `Factor`s span 2 categories: * Context (e.g., background, environment, access to resources, attention, working memory) * Skills (e.g., decoding, fluency, algebraic reasoning) `Factor`s may connect to other factors and can be linked to instructional strategies. | Property | Description | Type | Cardinality | | :--------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :------------------------------------------------------------------------------------------------------- | :---------- | | `academicSubject` | Academic subject | [`AcademicSubjectENUM`](/knowledge-graph/graph-reference/value-and-format-standards#academicsubjectenum) | 1 | | `attributionStatement` | Textual credit that acknowledges the source or creator of a work, included when required by the content’s license (e.g., Creative Commons BY);
