CDS Metrics API
API Metrics de CDS
CDS Metrics API is the part of the Curb Data Specification used to exchange curb-use sessions and aggregate measures with common definitions. It supports interpretation of activity over time, but comparisons still require compatible zone boundaries, reporting intervals, data coverage, and the chosen version’s calculation rules and fields.
Understanding the term
Metrics can summarize incomplete observations without repairing them. Publish coverage and quality limitations alongside aggregates so that a precise-looking value is not mistaken for complete ground truth.
An implementation should document its version, identifiers, time conventions, geographic accuracy, and supported fields. Test representative exchanges between the actual participating systems, including exceptions and updates. Assign responsibility for correcting discrepancies between published information, legal records, and the street. Collect only information needed for a defined purpose and apply suitable access and retention controls. A successful technical exchange does not by itself prove that the data is current, legally authoritative, or suitable for enforcement.
