| CUE merges the concepts of values and types. |
| Below is a demonstration of this concept, |
| showing respectively |
| some data, a possible schema for this data, |
| and something in between: a typical CUE constraint. |
| |
| {{< blocks/sidebyside >}} |
| <div class="col"> |
| <i>Data</i> |
| {{< highlight go >}} |
| moscow: { |
| name: "Moscow" |
| pop: 11.92M |
| capital: true |
| } |
| {{< /highlight >}} |
| </div> |
| |
| <div class="col"> |
| <i>Schema</i> |
| {{< highlight go >}} |
| municipality: { |
| name: string |
| pop: int |
| capital: bool |
| } |
| {{< /highlight >}} |
| </div> |
| |
| <div class="col"> |
| <i>CUE</i> |
| {{< highlight go >}} |
| largeCapital: { |
| name: string |
| pop: >5M |
| capital: true |
| } |
| {{< /highlight >}} |
| </div> |
| {{< /blocks/sidebyside >}} |
| |
| In general, in CUE one starts with a broad definition of a schema, |
| describing all possible instances, |
| and then narrows down these definitions for particular use cases |
| until a concrete data instance remains. |
