NAME

EPrints::Repository - Single connection to a specific EPrints Repository

User Comments


DESCRIPTION

This module is really a Repository, REALLY. The name is up to date and everything :-)

EPrints::Repository represents a connection to the EPrints system. It connects to a single EPrints repository, and the database used by that repository.

Each Repository has a "current language". If you are running in a multilingual mode, this is used by the HTML rendering functions to choose what language to return text in.

The Repository object also knows about the current apache connection, if there is one, including the CGI parameters.

If the connection requires a username and password then it can also give access to the EPrints::DataObj::User object representing the user who is causing this request. See current_user().

The Repository object also provides access to the XHTML class which contains many methods for creating XHTML results which can be returned via the web interface.
