The Catalog and Archive Service is a software component that
provides an extensible way to catalog and archive data. Products
can be inserted into the archive along with cataloging metadata.
Products, which are treated as collections of files by the
service, maintains versions of each released product and can
retrieve arbitrary versions. The service also provides the
capability of launching an open-ended set of triggered processing
rules that can validate data and metadata, derive products, run
analysis algorithms, and so forth.
