VHO Perl Module

The VHO-perl-0.9.3 Perl module provides access to the VHO API, the module takes care of setting up a connection to the Middleware and provides access to the functions of the Middleware. It allows application developers to have direct access to the API functionality and not have to re-create setup and function calls for each application. It also provides access to the most recent VHO WSDL file which completely describes the VHO service and the search types and data contained in it.

An example perl script employs the above mentioned Perl module to query and download the data.

VHO Java Code

VHO Java Code version 1.0.0 provides a Java implementation of the VHO API. It includes documentation and example use cases.

VHO General Analysis Package (VHOGAP)

The VHOGAP IDL save file (.sav) can be run with a licensed IDL version or with the free IDL Virtual Machine. It implements the VHO API along with plotting and data analysis routines. Users do not need to have data on their systems as the application will use the API to obtain the data from the VHO. Additionally, this application allows users to write their own pluggins and add their own analysis routines.
