Objectives and Needs#
The overall objective is to make it easier to find data through the CEOS Connected Data Assets which are CEOS-ARD compliant among the many collections available. The goal is to achieve this by better specifying this quality information in the collection metadata available in the CEOS Connected Data Assets. The recommendations can be applied by Data Producers to better describe their collections and will allow the CEOS Connected Data Assets to refine the filtering capabilities available to Data Consumers when searching for compliant data holdings.
Use Cases#
Below is an initial set of use cases. Not all of these use cases are applicable currently as this may require a refactoring of CEOS-ARD Product Family Specifications into multiple conformance classes. The use cases refering to compliance classes are a placeholder for a future evolution.
