Quality Distinctions:

As mentioned above, the quality of Earth science datasets can be broken down into high-level categories, hereby referred to as Science and Product. These distinctions were formally defined by the ESIP Information Quality Cluster (IQC), in close collaboration with the DQWG, and are well described in the following publication: http://dlib.org/dlib/july17/ramapriyan/07ramapriyan.html

More succinctly, these are defined as follows:

• Science Quality - Pertains to the data quality lifecycle/management phase that involves artifacts related to the defining, development, and validation of a particular version of dataset.

• Product Quality - Pertains to the data quality lifecycle/management phase that involves artifacts related to the production, assessment, and delivery of a particular version of a dataset. For the purpose of the DQWG, we have also included the ESIP IQC’s additional information quality categories (i.e., Service and Stewardship) within the “Product” category. For our specific purposes, Product Quality is therefore extended to also include artifacts originating from data quality lifecycle/management phases relating to maintenance, preservation, dissemination, enabling use, and providing users with support/services.
