Release 1.8.3 of Hyrax is for the HDF5 handler rewrite. The HDF Group, under a grant from NASA, have completed a major rewrite of the HDF5 handler for Hyrax. The new software no longer uses compile-time switches; instead it now uses a small set of run-time options. This means one binary distribution is all anyone needs and everyone can experiment with the new features. In short, the new features enable the software to read many more HDF5 files than before and to render them as CF-compliant data.

We have released an updated version of the loaddap command. This update fixes a few problems with recent versions of Matlab and includes tests that work without an extra, third-party, testing framework. Go to loaddap to get the new release or download to see all of our software downloads.

Announcing the first beta release of the OPeNDAP WCS Service

This service supports WCS 1.1 and is designed to be used in conjunction with one or more Hyrax data servers. The Hyrax servers may be either local or remote to the WCS service.

The WCS services uses semantic web technologies to create mappings between DAP data sets and WCS Coverages.

Hyrax 1.8.2 Update

We have pushed out an update for the Hyrax 1.8 release with fixes for the front end component of the server. All you need to do for this update is grab the OLFS package a Web ARchvie (war) file and drop it into tomcat's webapps directory; no need to restart the server. Get the update from the Hyrax 1.8 release page (where there is more information about the fixes) or here.

Matlab 2012a Includes Built-in Support for OPeNDAP!

Matlab 2012a was released on March 1 and includes the netcdf 4.1.2 library with OPeNDAP support turned on! This means that any OPeNDAP-served dataset that can be read with common netcdf applications (Panoply, Ferret, GrADS, IDV, …) can now be read using Matlab. 

I have released a bug fix update for the HDF5 Handler. This update includes fixes for the new H5.IgnoreUnknowTypes option and some (rare) uses of the varying length string type.

Released OLFS-1.9.1 - 

I just updated the current OLFS release for Hyrax 1.8.0. We found a couple of small issues in the OLFS-1.9.0 code and wanted to push a patch out right away. This does not affect the overall Hyrax version. If you have already downloaded Hyrax-1.8.0 you only need to update your OLFS distribution to the 1.9.1 package to get the full benefit of this upgrade. The downloads are available here.

We are almost ready to freeze the code base for the upcoming release of Hyrax 1.8.0.

So far the WCS code is still getting qualified and small bugs are being fixed everywhere...

Since moving from the old web site to this one we often get messages from people that say link X is now broken. In almost all cases link X looks like www.opendap.org/someplace/page.html and you've probably noticed that Drupal pages don't end in .html. For example, I got a message that www.opendap.org/download/hyrax.html was broken. The fix for this is to alias the broken URL to the correct Drupal node.

Making an alias

I've made a number of additions to the web site, particularly by adding modules that provide custom behavior. At the same time, I'd like to try using a blog to document the new features.
