ISO Aggregation
How ISO Does It
The ISO AggregateInformation object provides a powerful mechanism for grouping multiple metadata records into sets based on a number of relationships described by the AssociationType and InitiativeTypeCodes. Note that the sets are identified by MD_Identifiers which suggests that they could have metadata records of their own.

ESIP Response
- KB - GIS Bounding Environmental Observations, etc., Imagery Collections
- Tyler Stevens - GCMD DIF has "Parent"/"Child" relationships in metadata
- Jeff Arnfield - station metadata is often hierarchical, nested, or draws on other components. Our data products or datasets often involve aggregation
- James - OPeNDAP servers (really DAP Servers in general) need to support aggregation in several ways. We have use cases, part. tiles, and time series
- Ed Armstrong - Instruments > Missions > Campaigns
- Henry - aggregation from daily to monthly
- Rudy Husar
