The OpenXRI server-logic library contains the business logic for the OpenXRI server web application. Among other things, it can be used to manage the contents of an XRI authority resolution server, e.g. in order to register new i-names, modify XRDs, etc.
See the OpenXRI Server User Manual PDF in the Sourceforge repository.
The OpenXRI server-logic library is packaged as a .jar file for inclusion in other projects.
