The DLF's "ILS Discovery Interfaces"

I thought this would be of interest to our group:

"In 2007-2008, the Digital Library Federation (DLF) convened a Task Group to recommend standard interfaces for integrating the data and services of the Integrated Library System (ILS) with new applications supporting user discovery. This page gives access to the group's recommendation, related materials, and information on followup activities."

The Task Group's official recommendation, An API for effective interoperation between integrated library systems and external discovery applications, (revision 1.1) was released in December 2008.
