Educationrequirement

We use Drools in the educationrequirement module to implementing requirement rules. Requirement rules are defined in the Requirement_rule entity. These are generally things like age verification, presence checks or verifying a student has attended all mandatory modules of a course. A few base rules used to set the final status can be found in the ConclusionRules.drl file.

a rough overview how we build our knowledge base and start the evaluation

Facts

A summary for the available facts in the educationrequirement context. See the integration handbook for detailed documentation.

EntityFact

This used to work with entities in Drools. It’s possible to access the values of the entity and to resolve to other entities. An EntityFact of the Requirement being evaluated, the Schooling or Registration where the evaluation was started and the User they belong to will always be inserted into the knowledge base at the start.
