The file management component of a Catalog and Archive Service. This component purposefully separates data stores and metadata stores as standard interfaces, and provides some out of the box backend implementations of them (including one based on the javax.sql.DataSource interface). This component provides everything that you need to catalog, archive and manage files, and directories, and their associated metadata.

There is a newer version: 1.9.1
