On 8 May 2012 we presented a one-day course on server functions at NASA's Langely Research Center in Newport New, VA. The course covered how server functions work and how to write them. The class was built around a virtual machine running openSUSE Linux 12.1 that uses Vmware Fusion, Workstation or Player. With the virtual machine you get a complete development environment including Eclipse and a pre-compiled copy of Hyrax 1.8.2 - all ready to run.
Two presentations covering the DAP2 as it relates to the Open Geospatial Consortium (OGC). The first presentation covers the DAP2 data model and shows how it realtes to the OGC Abstract specification for Architecture. The second presentation relates the DAP2 data model to the OGC abstract specifaction for Coverages.
Presented at the 2012 OGC Technical Committee meeting in Austin, TX
This short set of four slides is a brief introduction to the WCS interface (aka Service End Point) that we developed as part work funded by NOAA under the IOOS program. The interface supports version 1.1.2 of teh WCS specification and uses semantic web technology to implement an extensible and scable framework for metadata translation.
These slides were presented at the eResearch 2011 meeting in Melbourne, Australia. The workshop covered both using a web browser as an OPeNDAP client as well as application-clients like Matlab and other tolls. Also covered are some issues relating to clients like configuration of the .dodsrc file to enable certificate-based authentication. There are four sets of slides included here that were used for this 1/2 day workshop.
The Paper: "Serving unstructured grids using OPeNDAP: Using server-side operations to subset and subsample data", by Christopher Barker and James Gallagher, was presented on Nov. 8th 2011 at the Twelfth International Conference on Estuarine and Coastal Modeling in St. Augustine, Florida. The paper described background and use-cases for accessing unstructured grid model data and work OPeNDAP is doing on developing server-side processing to support community needs.
Poster: "OPeNDAP's Server4: Building a High Performance Data Server for the DAP Using Existing Software" From the Fall 2006 AGU meeting in San Francisco.
This poster describes the design of OPeNDAP's new Data Server. This is the powerpoint file used to make the poster, so it's large. However, it will print well, so it's worth a look if you missed the meeting. The same poster is available as a PDF file.
This is the report from the first workshop (Sept 29 - Oct 1 1993) held when be began the development work that has ultimately lead to the formation of OPeNDAP (and DAP2, DAP4, Hyrax, et cetera). It's an interesting document from several persepectives, particularly for the things that have remained largely constant for nearly twenty years in the often fast-changing world of the web. Note that teh original design did not make use of the web infrastructure - that was not folded into the design until 1994, when NCSA's Mosaic browser really gained traction.
