The ToolsUI program handles all features of the enhanced data model. However, some of these features have not yet been extensively tested, due to lack of widespread use in the community. All of the features are also handled in the netCDF-Java library, also referred to as the Common Data Model (CDM) library, on which toolsUI is built. The IDV uses the CDM for data access, so it can handle data that is accessible through the CDM. However, some of the hooks are not there yet for handling data in forms supported by the enhanced data model but not provided yet by data providers. One of the problems is lack of conventions, such as the CF conventions, for best practices on how to use the enhanced data model for representing geoscience data. When there are multiple ways to represent some category of data, it is difficult to write software that understands all those different representations. Sometimes it's necessary to just choose one of many equivalent ways to represent data, to make it practical to adapt software to handle it. But developing conventions depends on data providers making use of the enhanced model to develop best practices and discover tradeoffs in various representations. The best practices have not yet crystallized from the fluid of experience providing and accessing data that uses the enhanced model. I've written about these issues in a white paper on "Developing Conventions for netCDF-4": http://www.unidata.ucar.edu/software/netcdf/papers/nc4_conventions.html If you begin making available data that uses the enhanced data model, you may become instrumental in establishing conventions for its use. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: WKW-744101 Department: Support netCDF Priority: Normal Status: Closed
