Web site. In particular, the Starlink open source software framework offers the tools to develop Message interoperability solutions. Currently, Starlink has been successfully used to dynamically generate CONNECTors directly between middleware protocols such as: CORBA to XML-RPC, and Service Location Protocol to Bonjour; it has also been used to build bridges between heterogeneous application systems eg a Flickr client application built using XML-RPC interoperating with the Picasa REST API. CONNECT has illustrated the possibilities of emergent solutions. However, the inherent openness and probability of such solutions raise important challenges, especially when deployed at Internet scale. Here it must be reliably able to produce correct mediators and also be secure against malicious threats, which are other areas of active research in CONNECT.
