ROC Data Model

The Repository Organized Curriculums (ROC) data model consists can be used to curriculum alignment data including curriculum standards, content correlations (content-standard links), and standards crosswalks (standard-standard links).

The summary section provides a condensed overview of all objects, with more details provided in following sections.

Summary

The following list contains all the different types of objects in the ROC data model. For each model, we provide links to the model definition (Django model class), auto-generated “rocdocs”, schema notes, and an example.

• Jurisdiction: a country or an organization that publishes curriculum data. model, rocdocs, example.

• Vocabularies and terms: are used to represent constants within each a jurisdiction (e.g. academic subjects, and grade levels)

  • ControlledVocabulary: model, rocdocs, example.

  • Term: model, rocdocs, example.

• Standards:

  • StandardsDocument: model, schema, rocdocs, example.

  • StandardNode: model, schema, rocdocs, example.

• Content:

  • ContentCollection: schema, model, rocdocs, example.

  • ContentNode: schema, model, rocdocs, example.

The ROC data model can also represent the following types of relations:

• TermRelation: model, rocdocs.

• ContentNodeRelation: model, rodocs.

• Content correlations: model, rodocs, example.

  • ContentStandardNodeRelation: schema, model, rocdocs, example.

• Standards crosswalks: model, rocdocs, example.

  • StandardNodeRelation: schema, model, rocdocs, example.

Prior work

The Repository of Organized Curriculums (ROC) data model is heavily inspired by the following prior work:

• ASN schema for curriculum standards and content correlations

• CASE schemas for curriculum standards

• LRMI specifications for content correlations

• Studio and Kolibri data model for content collections (channels) and content nodes
