Subject Management Business Rules

Please note that this page and related pages are being developed as part of the CIM Courses Project and are subject to change.

This page is intended to specify the business rules as they relate to Subject Management systems. These rules were developed as part of the CIM Courses Project.

*Please note that the term "must" is used intentionally to denote rules that must be followed and will be enforced by the API. Conversely, the term "should" is used to denote "soft" business rules that should be generally followed by are not enforced at the API level. In general, business rules of this type are handled via front-end validations.

Notes:

  1. CIM feed processing doesn't enforce that a value is present, but if it is present, it must be one of the allowed values.
  2. Validation enforced with a user prompt before save.
  3. Validation enforced by adding the attribute to the JSON before sending to the API
  4. This is a calculated value, rather than a user-supplied one. The calculation adheres to the rules.
