Objectives

Augment Giovanni, the Goddard online tool for data access, visualization and analysis, with semantic web technologies and ontologies to support data inter-comparisons from different sensors or models.

Data provenance (i.e. the essential data parameter details, quality and production caveats) will be added to enable researchers to make valid data comparisons and draw quantitative conclusions on specific analysis (e.g. ocean fertilization due to acid rain).

In the resulting Giovanni framework, the dataset variable characteristics and related quality can be encoded so that inter-comparison rules can be derived

Approach

• Capture scientist knowledge (rulesets) of the science & data quality characteristics
• Encode this knowledge so a computer can retrieve it
• Present only the safe comparisons, or the caveats for speculative comparisons
• Provide user-tunable quality screening
• Generate the Giovanni workflow and record the associated provenance
