What is OPeNDAP?
- OPeNDAP: Open-source Project for a Network Data Access Protocol
- OPeNDAP is a framework that simplifies all aspects of scientific data networking.
- OPeNDAP provides software which makes local data accessible to remote locations regardless of local storage format. OPeNDAP also provides tools for transforming existing applications into OPeNDAP clients (i.e. enabling them to remotely access OPeNDAP served data).
OPeNDAP in Tetherless World
Tetherless has been working with the developers of the next generation OPeNDAP that utilizes a flexible software framework for distribution of information, including but not limited to current OPeNDAP data response objects DAS, DDS, DataDDS, ASCII, Info, and HTML (the old .das, .dds, .dods, .ascii, .info, and .html extensions on the DAP URLs.)
The new framework incorporates a new stand-alone back end server (the BES) that responds to requests made by clients to create data views, access data views (das, dds, etc...), constrain data, aggregate data. The framework is a modular design which allows data providers to implement new data handlers easily, dynamically loading data modules into the BES, new data views, new aggregation methods, new reporting mechanisms, new transmission methods, new ways of providing data catalogs, and more.
Announcements
- 2009/07/08 Hyrax 1.5.2 Update - This update from 1.5.1 includes fixes for the attribute values shown in the DDX response - extraneous double quotes are that were added for the DAS print representation are no longer included in the DDX response. NetCDF Fileout fix: The 1.5.2 release includes an important fix for the netcdf fileout feature. The software was not bulding correct files from HDF4 data sets and was instead reusing dimensions in ways that made for some very confusing data files! It now works correctly.
- 2009/05/18 Hyrax 1.5.1 Update - This update includes a new version of libdap (3.9.3) that's binary-compatible with 3.9.2 and hdf4_handler 3.7.13. This update includes a fix for cached attribute objects and cache conrol for the hdf4 handler. You only need this update if the error with HDF4 attributes was a problem you need solved. Source code and both 32- and 64-bit Hyrax 1.5 binary packages (RPMs) for CentOS 5.2 are now available.
- 2009/04/27 Hyrax 1.5.0 Source code and Binaries for Hyrax 1.5.0 are now available.
- 2008/04/14 Hyrax 1.4.1 An update for Hyrax 1.4 is now available. This update fixes a memory error in the 1.4.0 version. You only need to update the BES for this update.
- 2008/02/29 Hyrax 1.4.0 Source code and Binaries for Hyrax 1.4.0 are now available. This release includes bug fixes for issues found in version 1.3.1 plus changes that have greatly increased response speeds and made the server easier to integrate with the look and feel of existing web sites.
