Uncertainty elements as stand-alone elements
At the moment the metadata models for uncertainty statements can only be used within the context of si:real, si:complex or si:list elements.
From various interested users of the D-SI data model, feedback was received that re-using the uncertainty models as stand-alone elements would be an advantage: E.g.:
- Semantic based data structures like RDF or Turtle can build up data by interconnecting data types from different domains.
- Advanced uncertainty statements based on fundamental uncertainty models
- Stand-alone covariance matrix (issue #17 (closed))
Suggested Changes
Adding the uncertainty related root elements
- si:expandedUnc
- si:coverageInterval
- si:ellipsoidalRegion
- si:rectangularRegion
- si:covarianceMatrix
In addition, to further improve re-use of the element outside XML, each of the uncertainty elements is provided through a stand-alone type definition:
- si:expandedUncType
- si:coverageIntervalType
- si:ellipsoidalRegionType
- si:rectangularRegionType
- si:covarianceMatrixType
