Abstract:
The OPeNDAP Data Access Protocol (DAP) is a protocol for requesting and
transporting data across the web. DAP 2.0 uses HTTP to frame the requests and
responses.
OPeNDAP has developed a software framework that simplifies all aspects of
scientific data networking, allowing simple access to remote data. Local data
can be made accessible to remote locations regardless of local storage format
by using
... servers. Existing, familiar data analysis and visualization
applications can be transformed into clients (i.e., applications able to access
remote served data).

OPeNDAP C++ 3.6 includes these major enhancements:
* Libdap 3.6 is now required by the new data handlers.
* Libdap removed old iostream methods, and others marked as
deprecated in the previous versions.
* Dap server no longer includes its own copy of the Perl
HTML::Parser module. The FilterDirHTML code now uses the current
distribution's version of the Filter.pm module.
* In dap server, dap_asciival filter now uses a new variant of the
Response class which reads and stores the version number correctly.
* In dap server, the web interface of help text is changed, and it
now uses a web page stored at the opendap web site.
