OGC 'apps to the data' architecture successfully applied: The Earth System Grid Federation (ESGF) Compute Challenge

The OGC Engineering Report OGC 19-003: Earth System Grid Federation (ESGF) Compute Challenge has now been published using the information gained from the Earth System Grid Federation extension to OGC Testbed-14, which successfully concluded in June, 2019. 

The T-14 ESGF extension demonstrated impressively how the ‘applications to the data’ architecture, developed in Testbed-13 and Testbed-14, is applicable to climate simulation data processing and analysis. The architecture builds on Web Processing Service profiles and metadata models to allow application developers to make their applications available to the community via Docker containers.

The Art of Discovery: Data, Services, and Applications

Discovery is an art, at least if the desired object is more complex than a simple blog web-page such as this one. Here we are talking about discovery of Earth Observation (EO) products, services providing on-demand processing capabilities, and applications that are not deployed yet but waiting in an application store for their ad-hoc deployment and execution. 

Instead of processing ever-increasing amounts of data locally, these applications are transferred to where the data resides. But how to discover these applications? How to understand what data an application can be applied to? How to chain applications? How to combine applications with already deployed services that provide data and data processing capabilities? All these aspects are now in focus of OGC Testbed-15.
