Hyrax by OPeNDAP logo OPeNDAP is pleased to announce Hyrax 1.6.2!

New Feature Summary:

  • Hyrax Directory Page (Index) Upgrades:
  • Webstart Viewer Links: Webstart column now contains links to external viewers for the dataset and supports the ability to add new ones
  • Server Context Customization: Renaming the opendap.war file to foobar.war results in the server context (root URL) becoming foobar --- for example, becomes
  • THREDDS Catalogs: Static THREDDS catalogs support inherited metadata for datasetScan elements.
  • RDF: Hyrax now supports transformations from the DDX response to RDF for semantic processing
  • Geogrid Function Additions
    • Multiple calls to geogrid() function are now supported in the constraint expression.
    • Supports optional arguments to designate coordinate dimensions on which to operate
  • NcML Module: Initial support for joinExisting aggregations on granules with explicitly listed join dimension sizes (i.e. ncoords attribute is required). This allows aggregations to be specified two ways:
    • Explicit lists of netcdf elements with ncoords attribute
    • Hyrax Extension: scan element allows specification of ncoords for the case where all granules have the same dimension size.
    [Please also see: Wiki documentation for the NcML Module].
  • HDF4 Handler: Improved support for HDF-EOS and common visualization tools such as IDV and Panoply (aka support for the COARDS conventions). See the README for more complete information.
  • Maintenance bug fixes and minor updates in other handlers. Please see individual handler pages for specifics.
