Documents are stored in any format as well as in more than one document format. The archive can handle related fields; the administrator decides what fields to use for each document.
Users can also view and search the archive through a configurable, extendable subject hierarchy . The software automatically performs data integrity checks. Some "stub" routines let individual sites add their own integrity checks.
Documents are submitted through a Web-based interface, and uploaded as files, in a compressed bundled file (such as a .zip file), or automatically mirrored from another site by specifying a URL.
Users subscribe either as authors or readers, via the Web or email. Authors have associated metadata. Submitted papers are entered directly or through a moderation process. This is done through the Web, as is most normal maintenance.
