Interoperability indicates the ability of different systems to work together (inter-operate). In information technology, it describes how effective systems or services are in exchanging information, thus facilitating functionality in one or more interoperating systems. (derived from http://en.wikipedia.org/wiki/Interoperability)
The Interoperability Working Group promotes the ability of Ex Libris systems to interoperate with each other and with third party systems, whether these are from other vendors or built by customers.
There is a mailing list for discussion on Interoperability called UB-INTEROPERABILITY-DISCUSS-L.
You can subscribe to the mailing list as long as your institution uses at least one Ex Libris product. Details on subscribing process are available at:
The working body and other information is available here.
