Traffic Light Extension Reference

This page gives an overview over the configuration of the traffic light extension. The extension shows a traffic light with either a green, yellow or red light, based on the evaluation of provision of metadata for each metadata record. Extension users can can configure which fields - depending on metadata record type - are evaluated; if weights for these fields should be included in the evaluation; and at which limits the traffic light switches color.

Weights enabled:


Traffic Light Color Value Ranges

The evaluation of the metadata provision always yields a value between 0 and 1. Depending on this value the traffic light either shows a green, yellow or red light. If no weights are applied, this value resolves to the percentage of filled metadata fields that are inculded in the calculation.

Green Light: 0.8 ≤ value ≤ 1
Yellow Light: 0.3 ≤ value < 0.8
Red Light: 0 ≤ value < 0.3

Evaluated Metadata Fields

Users of the extension can - for each metadata record type in the catalog - specify which metadata fields (and possibly with which weight) are evalauted with this extension, e.g., all optional metadata fields.
