Standard / ISO19115-3 / Quality report / Index descriptive results (#…

…8594)

ISO19115-3 adds possibility to provide descriptive results (and not only conformance and quantitative results). Properly index them in order to render them in measure table in record view (#7180)

This metadata element is used to describe the main sources of random and systematic error in the statistical outputs, and provide a summary assessment of all errors with special focus on the impact on key estimates. The bias assessment can be in quantitative or qualitative terms, or both. It should reflect the producer's best current understanding (sign and order of magnitude) including actions taken to reduce bias. Revision aspects should also be included here if considered relevant.</gco:CharacterString>
