What defines incremental changes in the context of metadata?

Incremental changes in the context of metadata refer specifically to modifications that build upon existing data rather than completely altering or removing it. This concept encompasses the idea of enhancing or expanding the current state without starting over from scratch.

When you make an addition to an existing file, you're acknowledging its current structure and functionality while improving it by integrating new elements. This aligns perfectly with the concept of incremental changes, as it allows for ongoing development and refinement without disruption to the existing framework.

In contrast, a complete replacement of the existing file fundamentally changes everything, which does not reflect the nature of incremental improvements. Similarly, deleting parts of a file detracts from its content, while restructuring an entire file implies a comprehensive overhaul rather than incremental adjustment. Each of these alternatives fails to illustrate the idea of gradual enhancement central to the definition of incremental changes.
