Reuters Holdings Plc’s Tibco Inc is expected to begin offering its core Tib middleware technology free over the Internet from this week, aiming to establish it as the de facto middleware standard. It aims to challenge the likes of Marimba Inc and PointCast Inc, licensing its technology to software and content creators that want to use it commercially to distribute their wares on the Internet. Tibco is also expected to name its first partners, including Microsoft Corp, which is likely to use the software in its Viper server for handling Web transactions. Palo Alto, California based Tibco’s Tib technology enables subject- based, rather than address-based, interchange of information between applications and is used in publish and subscribe communications middleware, including both real-time messaging and message queuing for secure delivery. It comes integrated with Tibco’s own Corba 2.0 compliant Common Object Request Broker. Tibco develops a host of end-to-end software on top of Tib. Further details were not forthcoming, as the company said that it was still all top secret.
