2 Definition​

Grouping of environmental data or products sharing common characteristics, represented by a single metadata record and consisting of one or more granules; also referred to as a dataset.

Notes​

Note that in these definitions of “collection” and “granule” that a collection is the minimum citable unit of data, akin to a journal article. This approach helps align data citation and publication with the much more mature practices surrounding journal article publication. In this alignment, granules can be thought of as the words in that article. This functional definition allows for flexibility as well; just as current science domains have their own standards for what qualifies as a minimally citable body of work that can go into a single journal article, different data domains across NOAA can do the same and determine what makes sense to go into one of their collections. If NOAA should ever reach a more detailed definition, adjustments can be made to align the collection metadata with that new definition.
