Datum is a concept of a reference point in architecture. In user interfaces, web and app alike, we also have a concept of datum. It manifests itself as a technological fabric (the reference point of how HTML is laid out), basic design principles (grid), and stylistic choices for a particular project (symmetry, contrast, key visual elements).
Datum is critical for building:
- grounding from technology (using the technology to render it, like web or native) and design (grid, rhythm) perspective
- establishing reference points (headers, title bar, navigation)
- guiding attention (key visuals, contrast)
In the end, notes are meaningless without the musical scale lines.
