All Implemented Interfaces:

ValidationRule<TincanManifest>

public class LaunchUrlRequiredRule
extends Object
implements ValidationRule<TincanManifest>

Validates that an xAPI package has a launch URL.

According to xAPI specification, at least one activity must have a launch attribute that serves as the entry point for the learning experience.

This rule defers validation when the activities list is null or empty, as that is handled by ActivitiesRequiredRule.
