Metadata standards are useful because they let us make meaningful connections between datasets.
Difficult to document dataset – currently at IRI user has to follow a series of links to find out about districts and related information
Would be nice if
Latter are local but solid; former are standard and possibly hazy
Given a dataset following one metadata standard, how do we make connections to datasets following a different standard?
Example: climate division outlines associated with climate division data are conceptually
Where location is a geometry (multipolygon)
This becomes nested sequences in OpenDAP
with some attributes
Point, LineString, Polygon, MultiPoint, MultiLineString,MultiPolygon,GeometryCollection
