The value of any data at NCI is considered at the Data Collection and SubCollection level, including funding arrangements for the storage allocations for each of the underlying data Subcollections.



Hierarchy Definitions

There are several definitions that are fundamental to how the data catalogue and data directories at NCI are organised: Dataset, Data Subcollection, Data Collection, Data Category and Dataset Granules. While there are a variety of definitions for the terms used that available from other sources, we use those listed below primarily because NCI’s focus is on programmatic access to data.
