Cardinality

Which means cardinality in mapping UBL + SK?

⚠ Machine-translated answer, not yet manually reviewed. For the exact wording, see the Slovak original.

Short answer

Cardinality says how many times an indication or group can in XML occur. For example, 0.1 means not more than once, 1.1 is mandatory once and 0..n is repeatable. In Slovak mappings, a distinction should be made between basic UBL Cardinality, rules EN 16931/Peppol and Slovak additions. However, cardinality itself does not replace business rules or the legal meaning of the figure.

0. 1

Optional not more than once

Data may be missing or given once.

1. 1

Mandatory once

The indication must be given if the rule applies.

0.n

Repeatable

The group may be repeated as necessary.

Business rules

Cardinality reads with context.

Conclusion

Cardinality is a technical navigation in a data model; correct e-invoice created only by combining cardinality, business rules, Slovak requirements and true content.
