When modeling data in a JCR, what should the model primarily utilize?

When modeling data in a Java Content Repository (JCR), the primary focus is on using IDs. This approach is essential because IDs uniquely identify each node within the repository, facilitating efficient data retrieval and manipulation. Utilizing IDs allows for a structured way to manage content, ensuring that every piece of data can be referenced and accessed consistently.

IDs can be hierarchical and often reflect the structure of the repository, enabling relationships between nodes to be modeled efficiently. This is crucial in systems like AEM (Adobe Experience Manager), where content and resources might require referencing in multiple contexts.

In contrast, using text descriptions, visual representations, or numeric values may supplement the information within the JCR but do not provide the same level of uniqueness and structural clarity as IDs do. These alternatives might enhance understanding or offer context but are less effective for the foundational elements of data modeling in JCR. The unique identification feature of IDs is paramount in ensuring integrity and accessibility in content management systems.
