What is a data product?
In the broadest sense products are data, from raw data to derivative results to high level knowledge summaries spanning entire scientific information domain.
EarthScope/USArray data product levels:0: Raw continuous and event-segmented data1: Quality controlled data2: Products derived from data using accepted methods3: Products needing technical analysis & interpretation4: Products integrating geological/geophysical data

The IRIS DMS data product effortMission: produce level 2 data products and manage products at all levels to provide:
Stepping stones (pre-processing) for further research
Insight into the data for selection and E&O Direct interpretation for confirmation, etc. Bridges to other disciplines, exporting seismological observations
Community guidance via a Data Products Working Group
