VOClient: Access the VO from Your Desktop

(version 1.0.0)

Access the VO from your desktop.

VOClient is package that lets you directly access services in the VO outside of a web browser. ¬†With the VOClient command-line tools you can carry out interactive VO research from a Unix (Mac or Linux) terminal. ¬†This includes discovering archives and catalogs through queries to the VAO Registry, searching and downloading images, spectra, and catalog records, and displaying datasets in other VO-compatible tools running on the desktop. ¬†You can use these same tools to create shell scripts that can customize your access to the VO. ¬†VOClient’s C-based libraries can also be used to create new VO tools or to enhance existing software with VO capabilities. The next release will include updated libraries with improved support for C/C++ software development as well as modules for Python scripting.
