DataCollection

vd
An extension to the core resource metadata (VOResource) that provides
a convention for describing data collections and their services in
a single resource (of type DataCollection2). It is leverages the
definitions in the VODataService extension.
A logical grouping of data which, in general, is composed of one
or more accessible datasets. A collection can contain any
combination of images, spectra, catalogs, or other data. All
access to the data, either via services or direct download, are
described here.
(A dataset is a collection of digitally-encoded data that
is normally accessible as a single unit, e.g. a file.)
This is intended to supercede the use of the resource types
DataCollection and DataService, as well as most uses of
CatalogService.
