ISO Quality Scope

How ISO Does It

ISO 19115 includes a Scope object that allows the specification of what elements in a dataset are described by some other object. This scope can be specified using the ScopeCode list, which is required, a spatial and temporal extent (optional), and a Description that provides more detail.

DQ_Scope
+ level: MD_ScopeCode
+ extent [0..1] : EX_Extent
+ levelDescription [0..*] : MD_ScopeDescription

EX_Extent
describes the spatial and temporal extent of the quality section.

MD_ScopeDescription
+ attributes : Set<GF_AttributeType>
+ features : Set<GF_FeatureType>
+ featureInstances : Set<GF_FeatureType>
+ attributeInstances : Set<GF_AttributeType>
+ dataset : CharacterString
+ other : CharacterString

ESIP Response

Ken Casey - All datasets we handle are like this. Exploring "Rich Inventory" and want to track results in a structured way, i.e. ISO 19115
Deborah Smith - some datasets, currently don't do
Jeff Arnfield - particularly with respect to the station metadata we receive / manage
Henry - the data quality varies, but we do not say it
Daniel Jacob
Ed Armstrong - Data quality can vary dramatically. Some users want the "bad" data.
Gao Chen, Kleb - NASA LARC - We need both data/measurment uncertainty and measurement consistency.
