CLOSED: NetCDF Uncertainty Conventions Email Discussion List
This mailing list is intended to encourage broad community input into an OGC discussion paper, netCDF Uncertainty Conventions (netCDF-U) 1.0. The intention is to use the email list to open the discussion to participants beyond the OGC member institutions.
The discussion paper proposes a set of conventions for managing uncertainty information within the netCDF classic (also known as netCDF3) data model and format.
The main mechanism for modeling uncertainty in netCDF-U files consists of annotating the netCDF data variables with uncertainty-related semantics based on the Uncertainty Markup Language (UncertML) dictionary.
The netCDF-U Conventions are applicable to data encoded in the netCDF3 format, with possible limitations, depending on conflicting conventions to which a given netCDF dataset may also be compliant. (A netCDF data set may be compliant with more than one convention.)
The netCDF-U Conventions are designed to be fully compatible with the netCDF Climate and Forecast Conventions (netCDF-CF), the de-facto standard for much of the data in the Fluid Earth Science community.
This discussion paper may relate to other OGC standards that make use of the netCDF3 data format, in particular the netCDF Encoding Format Extension of the Web Coverage Service Interface standard.
In addition, the work described in the paper may have implications for future OGC standards work directed at communicating geospatial data provenance and uncertainty in contexts other than netCDF.
