BExIS 2.5.0

With this release of the BExIS data management application the security system has been altered and extended following a number of user requests. Most importantly, the system now provides single sign-on authentication using the Lightweight Directory Access Protocol (LDAP). So users are now able to register with the system using existing credentials from their home organization, for example.

The security system is now based on the more common User/Group model instead of the User/Role model. This is primarily a name change. Upon another user request, permissions on dataset can now be specified more fine-grained (Create, View, Update, Delete, Download, Grant).

Another new feature of this release is that BExIS 2 now provides an export function for metadata. With this feature metadata structures are transformed into XML files comforming either to the EML or ABCD standard. This function is primarily designed for data managers and administrators who want to make selected datasets available for data discovery by external portals. This feature was developed through the German Federation for the Curation of Biological Data (GFBio).

In order to reduce the effort of setting up a new BExIS 2 instance the application is now shipped with a basic set of units and data types taken from the National Center for Biomedical Ontology.

Besides these new features, extensive testing has been conducted on all components, resulting once more in number of bugs and improvements being identified and fixed.
