PDS4: Meeting Big Data Challenges Via a Model-Driven Planetary Science Data Architecture and System

Abstract:

Big science data management entails cataloging, processing, distribution, multiple ways of analyzing and interpreting the data, long-term preservation, and international cooperation of massive amount of scientific data. PDS4, the next generation of the Planetary Data System (PDS), uses an information model-driven architectural approach coupled with modern information technologies and standards to meet theses challenges of big science data management. PDS4 is an operational example of the use of an explicit data system architecture and an ontology-base information model to drive the development, operations, and evolution of a scalable data system along the entire science data lifecycle from ground systems to the archives. This overview of PDS4 will include a description of its model-driven approach and its overall systems architecture. It will illustrate how the system is being used to help meet the expectations of modern scientists for interoperable data systems and correlatable data in the Big Data era.
