• Updated curriculum schema to version 2.0.0, modifying the structure to establish a 1:1 relationship with persons and an array of resources.
• Removed the "personId" property from the curriculum schema.
• Added "resources" array within the curriculum schema to hold resource objects with "resourceId" and "topicId" properties.
• Updated the configuration file to version 2.0.0 and removed the index on "personId" accordingly.
• Updated the test data in curriculum.json to reflect the new schema structure, ensuring each curriculum object contains an array of resources.

• Removed 'personId' field from the curriculum-2.0.0.json schema as '_id' will serve as the personId.
• Adjusted required properties, considering auto-save features.
• Introduced 'type' attribute for resource objects, distinguishing between 'topic' and 'adhoc'.
• Defined attributes based on resource type: 'resourceId' and 'topicId' for 'topic' type, and 'name' and 'link' for 'adhoc' type.
• Ensured all resource objects include 'review' and 'roadmap' properties.
• Enumerated roadmap values as 'completed', 'now', 'next', and 'later'.
• Researched and implemented the 'oneOf' construct for complex data structures in the JSON schema.
• Generated additional test data aligning with Topics and People datasets.
