History

The Goddard Earth Science Data and Information Services Center (GES DISC) developed Giovanni to easily explore, inter-compare, and analyze data using only a Web browser. Giovanni employs scientifically valid algorithms and a rich schema for describing data parameters, a combination that provides users with scientifically meaningful results. This, sometimes subtle, distinction is often overlooked in other online data visualization and analysis tools. The current version of Giovanni, version 3, evolved from the successes of previous versions that emphasized a simple interface, rapid image rendering, and scientifically valid processing that correctly accounted for the algorithms employed (including underlying assumptions). Based on Common Gateway Interface (CGI) Perl scripts, HyperText Markup Language (HTML) templates, and GrADS (Grid Analysis and Display System) scripts, the early versions of Giovanni were enormously successful and deployments at the GES DISC quickly proliferated. Although successful, the architecture was based on old technology. The costs to maintain and extend Giovanni for new science driven requirements and for supporting standard interfaces and protocols became too great. As a result, a radical departure for a new Giovanni architecture was undertaken. The result was Giovanni, version 3. Giovanni is based on a services oriented architecture (SOA) supported by a workflow management system. It is designed to be extensible with respect to new science requirements and interoperable with standard protocols and data formats.
